Segment selection for fusion and artificial disc replacement in the hybrid surgical treatment of noncontiguous cervical spondylosis: a finite element analysis. Front Bioeng Biotechnol 2024; 12:1345319. [PMID: 38633668 PMCID: PMC11021715 DOI: 10.3389/fbioe.2024.1345319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 03/15/2024] [Indexed: 04/19/2024] Open
Abstract
Introduction: The treatment of skip-level cervical degenerative disease (CDD) with no degenerative changes observed in the intervening segment (IS) is complicated. This research aims to provide a reference basis for selecting treatment approaches for noncontiguous CDD. Methods: To establish accurate finite element models (FEMs), this study included computed tomography (CT) data from 21 patients with CDD (10 males and 11 females) for modeling. The study primarily discusses four cross-segment surgical approaches: upper (C3/4) anterior cervical discectomy and fusion (ACDF) and lower (C5/6) cervical disc arthroplasty (CDA), FA model; upper CDA (C3/4) and lower ACDF (C5/6), AF model; upper ACDF (C3/4) and lower ACDF (C5/6), FF model; upper CDA (C3/4) and lower CDA (C5/6), AA model. An initial axial load of 73.6 N was applied at the motion center using the follower load technique. A moment of 1.0 Nm was applied at the center of the C2 vertebra to simulate the overall motion of the model. The statistical analysis was conducted using STATA version 14.0. Statistical significance was defined as a p value less than 0.05. Results: The AA group had significantly greater ROM in flexion and axial rotation in other segments compared to the FA group (p < 0.05). The FA group consistently exhibited higher average intervertebral disc pressure in C2/3 during all motions compared to the AF group (p < 0.001); however, the FA group displayed lower average intervertebral disc pressure in C6/7 during all motions (p < 0.05). The AA group had lower facet joint contact stresses during extension in all segments compared to the AF group (p < 0.05). The FA group exhibited significantly higher facet joint contact stresses during extension in C2/3 (p < 0.001) and C6/7 (p < 0.001) compared to the AF group. Discussion: The use of skip-level CDA is recommended for the treatment of non-contiguous CDD. The FA construct shows superior biomechanical performance compared to the AF construct.

Combination of neuroendoscopic hematoma evacuation and endovascular coil embolization for a ruptured anterior choroidal artery aneurysm in patients with moyamoya disease: illustrative cases. JOURNAL OF NEUROSURGERY. CASE LESSONS 2024; 7:CASE23677. [PMID: 38467048 PMCID: PMC10936939 DOI: 10.3171/case23677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Accepted: 02/02/2024] [Indexed: 03/13/2024]
Abstract
BACKGROUND The treatment strategy for hemorrhagic moyamoya disease (MMD) due to a ruptured aneurysm at the distal portion of the anterior choroidal artery remains controversial. The authors successfully treated the ruptured aneurysm with neuroendoscopic hematoma evacuation, followed by endovascular coil embolization. OBSERVATIONS The authors encountered two patients with massive hemorrhagic MMD whose MMD had already been diagnosed and who had a periventricular anastomosis due to a ruptured aneurysm of the distal portion of the anterior choroidal artery involving the periventricular anastomosis. In both cases, neuroendoscopic hematoma evacuation was performed for hemorrhagic MMD in the acute phase, followed by endovascular coil embolization of the ruptured aneurysm in the chronic phase. In both endovascular treatments, the patient's condition was stabilized by hematoma evacuation, allowing a detailed preoperative evaluation of the anatomical findings of the vessel and functional findings of intraoperative neurophysiological monitoring using continuous monitoring of motor evoked potentials to preserve motor function. LESSONS Combination therapy can be useful for hemorrhagic MMD in patients with diagnosed MMD with a periventricular anastomosis. Additionally, a preoperative understanding of the vascular construction and intraoperative neurophysiological monitoring will aid in the successful coil embolization of aneurysms at the distal portion of the anterior choroidal artery with hemorrhagic MMD.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE Examine the clinical evidence for the use of osteobiologics in hybrid surgery (combined anterior cervical discectomy and fusion (ACDF) and total disc replacement (TDR)) in patients with multilevel cervical degenerative disc disease (DDD). METHODS PubMed and Embase were searched between January 2000 and August 2020. Clinical studies investigating 18-80 year old patients with multilevel cervical DDD who underwent hybrid surgery with or without the use of osteobiologics were considered eligible. Two reviewers independently screened and assessed the identified articles. The methodological index for non-randomized studies (MINORS) tool and the risk of bias (RoB 2.0) assessment tool were used to assess risk of bias. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to evaluate quality of evidence across studies per outcome. RESULTS Eleven studies were included. A decrease in cervical range of motion was observed in most studies for both the hybrid surgery and the control groups consisting of stand-alone ACDF or TDR. Fusion rates of 70-100% were reported in both the hybrid surgery and control groups consisting of stand-alone ACDF. The hybrid surgery group performed better or comparable to the control group in terms of adjacent segment degeneration. Studies reported an improvement in visual analogue scale for pain and neck disability index values after surgery compared to preoperative scores for both treatment groups. The included studies had moderate methodological quality. CONCLUSIONS There is insufficient evidence for assessing the use of osteobiologics in multilevel hybrid surgery and additional high quality and controlled research is deemed essential.

Sagittal sequence and clinical efficacy of cervical disc replacement and hybrid surgery in the treatment of cervical spondylotic myelopathy: a retrospective study. Front Surg 2024; 10:1265349. [PMID: 38249309 PMCID: PMC10797051 DOI: 10.3389/fsurg.2023.1265349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Accepted: 11/13/2023] [Indexed: 01/23/2024] Open
Abstract
Background Hybrid surgery (HS) combines anterior cervical discectomy and fusion (ACDF) with cervical disc replacement (CDR) is gradually being more frequently implemented, but there are few studies reporting the safety and effectiveness of hybrid surgery in three levels cervical spondylotic myelopathy. Methods The clinical and radiographic data of patients with three-segment cervical spondylosis, who underwent CDR, ACDF and HS in our hospital from February 2007 to February 2013 were analyzed. The Visual Analog Scale (VAS), Japanese Orthopedic Association (JOA) and Neck Disability Index (NDI) were used to evaluate the clinical efficacy post surgery. Cervical spine x-rays were conducted to assess ROM, CL, T1S and relevant outcomes. Results A total of 94 patients were included in the study: 26 in the CDR group, 13 in the HS1 group, 31 in the HS2 group, and 24 in the ACDF group. Most patients in the CDR group were younger. There was no difference in the follow-up duration, blood loss volume or surgery time (P > 0.05). Four groups reported improvements in JOA and NDI scores compared to baseline. There was no significant difference in the final JOA, final NDI or recovery rate among the 4 groups. The final ROM was smaller in the ACDF group than in the other 3 groups. There was no difference among the four groups in the final UROM, final LROM or their changes. There was no difference in the final T1S, final SVA or their change among the four groups. All groups showed similar changes in CL and T1S-CL. Conclusions There was no difference in the clinical outcomes of ACDF, CDR, or hybrid surgery. CDR can better preserve the mobility of the cervical spine. Neither CDR nor hybrid surgery was significantly advantageous over ACDF in restoring the sagittal sequence in patients with three-level CSM.

Abstract
PURPOSE To report the performance of surgical treatment (ST), hybrid treatment (HT), and endovascular treatment (ET) for patients with acute limb ischemia (ALI). METHODS This is a retrospective, comparative study of all consecutive patients with ALI treated in 2 tertiary centers between April 2010 and April 2020. Amputation and/or death (amputation-free survival; AFS) was the primary composite endpoint. Mortality, major amputation, and reintervention during follow-up were additionally analyzed. Proportional hazards modeling was used to identify confounders, results are presented as hazard ratio (HR) and 95% confidence intervals (CIs). RESULTS In total, 395 patients (mean age=71.1±13.6 years; 51.1% female) were treated during the study period. Surgical treatment was preferred in 150 patients (38%), while 98 were treated by HT (24.8%) and 147 by ET (37.2%). Rutherford class IIa was the most common clinical presentation in the ET group (50.3%), whereas Rutherford IIb was most common in the ST (54%) and HT (48%) groups (p<0.001). Significantly, more patients presented with a de novo lesion in the ST and HT groups (79.3% and 64.3%, respectively) compared with ET (53.7%; p<0.001). Median follow-up was 20 months (range=0-111 months). In the multivariate analysis, ET showed significantly better AFS during follow-up compared with ST (HR=1.89, 95% CI=1.2-2.9, p<0.001) and HT (HR=1.73, 95% CI=1.1-3.1, p<0.001). Mortality during follow-up was also significantly lower after ET compared with ST (HR=2.21, 95% CI=1.31-3.74, p=0.003) and HT (HR=2.04, 95% CI=1.17-3.56, p=0.012). Endovascular treatment was associated with lower amputation rate compared with ST (HR=2.27, 95% CI=1.19-4.35, p=0.013) but was comparable with HT (HR=2.00, 95% CI=0.98-4.06, p=0.055). Reintervention rates did not differ significantly between the groups (ET vs ST: HR=1.52, 95% CI=0.99-2.31, p=0.053; ET vs HT: HR=1.3, 95% CI=0.81-2.07, p=0.27). CONCLUSION Endovascular treatment for ALI was associated with improved AFS and comparable reintervention rates compared with open surgical and hybrid therapy. CLINICAL IMPACT Treatment of acute lower limb ischemia remains a challenge for clinicians with high morbidity and mortality rates. Endovascular revascularization is considered first line treatment for many and hybrid treatments are becoming more common, however data is limited to either old trials, small series or with short follow-up. We present herein our 10-year experience with all available devices and techniques for open surgical, endovascular and hybrid acute limb ischemia treatments and compare their outcomes.

Abstract
PURPOSE To compare the mid-term outcomes of endovascular and hybrid procedures in treating aortic arch pathologies with an unfavorable proximal landing zone, and analyze the different indications of the 2 methods. METHODS We collected the clinical data from 59 patients with complex aortic arch pathologies who underwent endovascular or hybrid surgery from March 2018 to April 2020 at a single center. Among the patients, 45 were treated by branched or fenestrated surgery and 14 by hybrid surgery. The clinical data of preoperative, perioperative, and postoperative results were retrospectively analyzed and compared. The main study indexes were the branch patency rate and endoleakage rate during the follow-up period. The secondary study indexes included the operation success rate, operative time, hospital expenses, complication incidence, freedom from reintervention rate, mortality, etc. RESULTS The operation success rate of all the groups was 100%. The hospital expenses of the hybrid group were lower than those of the endovascular group (p<0.05). The operative time of the hybrid group was longer than that of the endovascular group (p<0.05). The incidence of anatomic variants in the hybrid group was 28.6%, which was significantly higher than that in the endovascular group (2.2%, p=0.011). However, there were no significant differences in operative bleeding, ventilator use duration, and treatment time in intensive care units between the 2 groups (p>0.05). Follow-up was conducted for a period of 12 to 34 months. Four patients of the hybrid group experienced numbness of the upper limb (28.57%); the proportion was higher than the endovascular group (0%, p=0.002). There were no significant differences in the occurrence of endoleaks, retrograde aortic dissection, target lesion, secondary operation, branch patency rate, paraplegia, cerebral apoplexy, renal failure, or other complications in either group (p>0.05). The mortality of the endovascular group was 6.67% (3/45). Overall cumulative survival at 1 year was 100% in the hybrid group and 93.3% in the endovascular group. There was no statistical difference in the increase of the true lumen between the 2 groups for vascular remodeling (p>0.05). CONCLUSION The hybrid surgery costs less and proves more suitable for treating variants of the aortic arch. The endovascular treatment still has limitations due to anatomical conditions.

Hybrid surgery management challenges of a Behcet's disease patient with recurrence of aortic aneurysms: a case report. Front Cardiovasc Med 2023; 10:1097129. [PMID: 37719979 PMCID: PMC10502721 DOI: 10.3389/fcvm.2023.1097129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Accepted: 07/28/2023] [Indexed: 09/19/2023] Open
Abstract
Background Behcet's disease is a vasculitis of unknown origin that can involve multiple organs or tissues. Aneurysm or pseudoaneurysm, also one of the complications of Behcet's disease, is usually accompanied by a poor prognosis. Surgery is usually accompanied by a high risk of complications, such as the recurrence of anastomotic pseudoaneurysms and blockage of the target vessel. Using hybrid surgery, we successfully treated a complex and recurrent abdominal aortic pseudoaneurysm in a patient with BD. Methods We report a 32-year-old female diagnosed with Behcet's disease with recurrent thoracoabdominal aortic aneurysm. Adequate immunotherapy was given during the perioperative period. The splanchnic artery branches were reconstructed, and the aneurysm was sequestered with endovascular repair. The patient recovered uneventfully and was discharged from the hospital 8 days after hybrid surgery. At the 60-month follow-up, no aneurysm was observed, the stent had no displacement or internal leakage, and the reconstructed blood vessels were unobstructed. Conclusion Hybrid surgery could be a feasible and effective strategy for BD aneurysms. Adequate preoperative and postoperative immunotherapy with arterial anastomosis away from the diseased artery may be the key to success.

Debranching abdominal aortic hybrid surgery for aortic diseases involving the visceral arteries. Front Cardiovasc Med 2023; 10:1219788. [PMID: 37522078 PMCID: PMC10374220 DOI: 10.3389/fcvm.2023.1219788] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 06/15/2023] [Indexed: 08/01/2023] Open
Abstract
Objective Aortic diseases involving branches of the visceral arteries mainly include thoracoabdominal aortic aneurysm (TAAA), aortic dissection (AD) and abdominal aortic aneurysm (AAA). The focus of treatment is to reconstruct the splanchnic arteries and restore blood supply to the organs. Commonly used methods include thoracoabdominal aortic replacement, thoracic endovascular aortic repair and hybrid approaches. Hybrid surgery for aortic disease involving the visceral arteries, consisting of visceral aortic debranching with retrograde revascularization of the celiac trunk and renal arteries and using stent grafts, has been previously described and may be considered particularly appealing in high-risk patients. This study retrospectively analyzed recorded data of patients and contrasted the outcomes with those of a similar group of patients who underwent conventional open repair surgery. Methods Between 2019 and 2022, 72 patients (52 men) with an average age of 61.57 ± 8.66 years (range, 36-79 years) underwent one-stage debranching abdominal aortic hybrid surgery. These patients, the hybrid group, underwent preoperative Computed Tomographic Angiography (CTA) and had been diagnosed with aortic disease (aneurysm or dissection) involving the visceral arteries and were at high risk for open repair. The criteria used to define these patients as high-risk group who are in the need of hybrid treatment were American Society of Anesthesiologists (ASA) class 3 or 4. In all cases, we accomplished total visceral aortic debranching through a previous visceral artery retrograde revascularization with synthetic grafts (customized Y or four-bifurcated grafts), and aortic endovascular repair with one of two different commercially produced stent grafts (Medtronic® and Lifetech®). In some cases, we chose to connect the renal artery to the artificial vessel with a stent graft (Viabahn) and partly or totally anastomosed. We analyzed the results and compared the outcomes of the hybrid group with those of a similar group of 46 patients (36 men) with an average age 54.15 ± 12.12 years (range, 32-76). These 46 patients, the conventional open group, were selected for having had thoracoabdominal aortic replacement between 2019 and 2022. Results In the hybrid group, 72 visceral bypasses were completed, and endovascular repair was successful in all cases. No intraoperative deaths occurred. Perioperative mortality was 2.78%, and perioperative morbidity was 9.72% (renal insufficiency in 1, unilateral renal infarction in 5, Intestinal ischemia in 1). At 1-month postoperative CTA showed 2 endoleaks, one of which was intervened. At follow-up, there were unplanned reoperation rate of 4.29% and 5 (7.14%) deaths. The remaining patients' grafts were patent at postoperative CTA and no endoleak or stent graft migration had occurred. In the conventional open group, 1 died intraoperatively, 4 died perioperatively, perioperative mortality was 10.87% and complications were respiratory failure in 5, intestinal paralysis/necrosis in 4, renal insufficiency in 17, and paraplegia in 2. At follow-up, 5 (12.20%) patients presented with synthetic grafts hematoma 4 (9.76%) patient died, and 6 (14.63%) patients required unplanned reoperation intervention. Conclusion Hybrid surgery is technically feasible in selected cases. For aortic diseases involving the visceral arteries, the application of hybrid abdominal aorta debranching can simplify the operation process, decrease the risks of mortality and morbidity in high-risk and high-age populations and decrease the incidence of various complications while achieving ideal early clinical efficacy. However, a larger series is required for valid statistical comparisons, and longer follow-ups are necessary to evaluate the long-term efficacy of hybrid surgery.

Abstract
A pseudoaneurysm of the profunda femoris artery (PFA) is a rare disease induced by femoral trauma, proximal femoral fracture, or iatrogenic causes associated with orthopaedic surgery. Recently, transcatheter arterial embolism was reported as an effective treatment for profunda femoris artery pseudoaneurysm. This report presents the case of an 85-year-old male who underwent artificial head replacement for a left femoral neck fracture and was hospitalized with a peri-stem fracture four years later. Conservative treatment was conducted with a brace, though the swelling and pain in his left thigh increased one week after his hospital admission. Contrast-enhanced computed tomography (CT) led to a diagnosis of a left profunda femoris artery pseudoaneurysm, and the patient underwent emergency transcatheter arterial embolism and surgical hematoma removal. Since the emergency surgery, the patient's course has been good, and he has been undergoing rehabilitation.

Abstract
Anterior cervical discectomy and fusion (ACDF) has long been the standard surgical treatment for cervical degenerative disc disease (DDD); however, cervical artificial total disc replacement (cTDR) has gained increasing recognition in recent years due to its ability to maintain a natural range of motion and lower the rate of adjacent segment disease. Although cTDR is only approved for one or two levels in the United States, it has been used for three or more levels in other countries. We present a case of a 59-year-old male patient who underwent three-level cTDR (C4-C7) in Germany and presented 10 years later with progressive paracervical pain and worsening dysphagia. Magnetic resonance imaging (MRI) and computed tomography (CT) scan showed hardware loosening, progressive loss of bone around the device, and a cyst ventral to C4-C5 with mass effect on the hypopharynx. The patient was successfully treated with posterior cervical fusion and showed improvement in neck pain. This case underscores the significance of long-term follow-up and thoughtful consideration when selecting an appropriate treatment modality for patients afflicted with cervical DDD.

Abstract
Objective Although endovascular recanalization is considered a more effective treatment for chronic internal carotid artery occlusion (CICAO), the success rate of complex CICAO remains inadequate. We present hybrid surgery (carotid endarterectomy combined with carotid stenting) for complex CICAO and explore the influential factors and effects of hybrid surgery recanalization. Methods We retrospectively analyzed the clinical, imaging, and follow-up data of 22 patients with complex CICAO treated by hybrid surgery at the Zhongnan Hospital of Wuhan University from December 2016 to December 2020. We also summarize the technical points related to hybrid surgery recanalization. Results A total of 22 patients with complex CICAO underwent hybrid surgery recanalization. There were no postoperative deaths in all patients after hybrid surgery recanalization. Nineteen patients successfully underwent recanalization with a success rate of 86.4% and three cases with a failure rate of 13.6%. Patients were divided into success and failure groups. Significantly different radiographic classification of lesions was observed between the success group and the failure group (P = 0.019). The rates of CICAO with reverse ophthalmic artery blood flow in the internal carotid artery (ICA) preoperatively were 94.7% in the success group and 33.3% in the failure group (P = 0.038). Three cases of hybrid surgery recanalization failure were transferred for EC-IC bypass and had good neurological recovery. Postoperative average KPS scores of the 19 patients were improved compared to the preoperative ones (P < 0.001). Conclusion Hybrid surgery for complex CICAO is safe and effective with a high recanalization rate. The recanalization rate is related to whether the occluded segment surpasses the ophthalmic artery.

Abstract
Purpose To study and compare the clinical outcomes of endovascular therapy with those of hybrid surgery in the treatment of Trans-Atlantic Inter-Society Consensus II (TASC II) D aortoiliac occlusive disease (AIOD). Patients and Methods Patients with TASC II D-type AIOD who underwent their first surgical treatment at our hospital between March 2018 and March 2021 were enrolled and followed up to evaluate the improvement in symptoms, complications, and primary patency. The Kaplan-Meier method was used to compare the differences in primary patency between the treatment groups. Results In total, 132 of 139 enrolled patients (94.96%) achieved technical success following treatment. The perioperative mortality rate was 1.44% (2/139), and postoperative complications occurred in two patients. Among the patients who successfully underwent surgery, 120 underwent endovascular treatment (110 patients with stenting and 10 patients with thrombolysis before stenting), 10 underwent hybrid surgery, and 2 underwent open surgery. The follow-up data were compared between the endovascular and hybrid groups. At the end of the follow-up period, the patency rates in the hybrid and endovascular groups were 100% and 89.17% (107/120), respectively. The endovascular group achieved primary patency rates of 94.12%, 92.44%, and 89.08% at 6, 12, and 24 months postoperatively, respectively, whereas the primary patency rate remained at 100% in the hybrid group, with no significant variation between the endovascular and hybrid groups (P = 0.289). The endovascular group was further divided into a stent subgroup (110 patients) and a thrombolysis/stent subgroup (10 patients), and no prominent variation was noted in the primary patency between the two subgroups (P = 0.276). Conclusion Although open surgery is the gold standard treatment for TASC II D-type AIOD, endovascular and hybrid treatments are feasible and effective. Both methods showed good technical success and early to midterm primary patency rates.

Abstract
Recanalization of chronic occluded internal carotid arteries has the potential to provide significant benefits for patients in the future, but the procedure is technically challenging. Therefore, this study aimed to identify a better method to predict the success of recanalization for patients with chronic internal carotid artery occlusion. The study's overall success rate was 73.77%. The multivariate logistic regression analysis revealed that two factors were independent predictors of successful recanalization: the continuous low signal lumen in the occluded segment of the internal carotid artery on the MRI image without contrast (OR: 15.9; 95% CI: 2.67-94.63) and the architecture of the clinoid segment of the internal carotid artery on the MRI image with contrast (OR: 11.97; 95% CI: 2.44-58.79). Based on the model coefficient, the researchers established an MRI score system. The MRI score system's area under the curve (AUC) in predicting successful recanalization was 0.916 (95% CI: 0.815 to 0.972; p < 0.001) with a sensitivity of 83.33% and a specificity of 72.22%. Compared to the previous score system based on the DSA morphology, the MRI system had a similar sensitivity and a better specificity. Therefore, the continuous low signal lumen in the occluded segment of the internal carotid artery on the MRI image without contrast and the architecture of the clinoid segment of the internal carotid artery on the MRI image with contrast were identified as independent predictors for successful recanalization in patients with chronic internal carotid artery occlusion (CICAO).

Abstract
OBJECTIVE Accessory renal artery (ARA) is a common variant of renal vessels. Currently, there are some controversies about reconstruction strategy and few cases reported in the literature. Individualized treatment should be carried out according to preoperative renal function evaluation and technical level. METHODS In this paper, a 50-year-old male patient was reported, who developed a dissecting aneurysm after thoracic endovascular aortic repair (TEVAR) and needed further intervention. Imaging showed that the left kidney was supplied by bilateral renal artery (false lumens), and there were left renal malperfusion complicated with abnormal renal function. RESULTS Autologous blood vessels were used to successfully reconstruct ARA with during hybrid surgery. Renal perfusion and renal function recovered rapidly after operation. There was no abnormality in renal indexes after 3 months follow-up. CONCLUSION It is beneficial and necessary to reconstruct ARA for patients with renal malperfusion or abnormal renal function before operation.

Abstract
The accuracy of the Newtonian model used in retrograde visceral revascularization (RVR) of hybrid surgery for thoracoabdominal aortic aneurysm (TAAA) hemodynamic simulation remains unclear. Noting that an appropriate blood viscosity model is a significant factor to capture hemodynamic changes in numerical studies. Therefore, both Newtonian and non-Newtonian blood viscosity models were adopted in this study to investigate the importance of hemodynamics when non-Newtonian blood property was accounted for in a patient-specific RVR simulation. The results revealed that disturbed flow and unfavorable WSS distribution can be observed in the anastomosis region under both blood viscosity models due to the retrograde flow pattern in the RVR model. However, although the non-Newtonian blood model has negligible effect on flow pattern and pressure drop, there were of significance quantitative and qualitative difference of local normalized helicity and wall shear stress distribution under pulsatile flow condition. In particular, the unfavorable WSS indicators distribution was better matched with a patient-specific follow-up report when non-Newtonian blood viscosity was accounted for. To conclude, the use of a Newtonian blood model is a reasonable approximation to obtain the general features of the flow field under steady flow condition. However, to study the hemodynamic parameters within retrograde flow under pulsatile flow condition, a non-Newtonian model may be more appropriate.

Hybrid uniportal robotic-assisted thoracoscopic surgery using video-assisted thoracoscopic surgery staplers: technical aspects and results. Ann Cardiothorac Surg 2023; 12:34-40. [PMID: 36793988 PMCID: PMC9922775 DOI: 10.21037/acs-2022-urats-140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 12/13/2022] [Indexed: 01/01/2023]
Abstract
Background The clinical efficacy of robot-assisted thoracic surgeries has been explored by numerous recent studies. Nonetheless, since current standard robotic systems (da Vinci Xi system) were intended for multiportal surgical processes and robotic staplers were still unavailable in the developing world, obstacles still remain concerning the feasibility of uniportal robotic surgeries. Methods A hybrid uniportal robotic-assisted thoracoscopic surgery (RATS) modality utilizing video-assisted thoracoscopic surgery (VATS) staplers was investigated in Shanghai Pulmonary Hospital. Clinicopathological characteristics and perioperative outcomes concerning patients receiving hybrid uniportal RATS between August 2022 and September 2022 were collected. Results A total of 40 patients were included in this study. Most of the patients (23/40, 57.5%) received hybrid uniportal RATS lobectomies. One conversion from uniportal RATS to biportal process was encountered due to extensive adhesions discovered intraoperatively. The median procedural duration was 76 min [interquartile range (IQR), 61-99 min], and the median blood loss volume was 50 mL (IQR, 50-50 mL). A median stay length of three days (IQR, 2-4 days) was recorded. Eleven patients (27.5%) developed Clavien-Dindo grade I-II postoperative complications, while no grade III-IV complications were observed. Aside from this, none of the patients were readmitted or died within 30 days post-surgery. Conclusions The feasibility of hybrid uniportal RATS procedures using VATS staplers has been preliminarily validated. For early-stage non-small cell lung cancer patients, such a procedure might clinical efficacy comparable to that of uniportal RATS utilizing robotic staplers.

Abstract
BACKGROUND The cervical paraspinal muscle (CPM) has an essential role in positioning, stabilizing and directing the cervical spine. However, information is lacking regarding the influence of CPM on outcomes following anterior cervical surgery. This study aims to evaluate the association of fatty infiltration (FI) of CPM with postoperative outcomes in patients undergoing hybrid surgery (HS) and analyze the relationship between FI and cross-sectional area (CSA) of CPM. METHODS A retrospective analysis was performed on 110 consecutive patients undergoing continuous 2-level HS. According to Goutallier classification of multifidus FI, the patients were divided into normal, moderate, and severe groups. Image J software was employed to outline and analyze CPM. Clinical outcomes and radiographic parameters were collected and evaluated for relevant comparisons. RESULTS Visible FI was identified in 69.1% of patients (76/110), with a propensity in elderly patients (p = 0.053). No statistically significant differences were presented among the three groups regarding pre- and postoperative clinical evaluation scores. The cervical lordosis was significantly higher in the normal group before surgery (p = 0.029). Likewise, the sagittal vertical axis (SVA) was significantly higher in the severe group than the normal group at the final follow-up (p = 0.046). The function spine unit angle and disc angle of arthroplasty levels were significantly lower in the severe group than the normal group at follow-ups. Moreover, after correction according to vertebral body area, no statistically significant relationship existed between CSA ratio and FI grade. CONCLUSION CPM degeneration is common and age-related in patients with cervical disc degenerative disease. More importantly, there was a significant positive correlation between severe FI of CPM and postoperative sagittal balance disorder, particularly in C2-7 SVA and segmental alignment of arthroplasty level. Meanwhile, FI of CPM appears to have no impact on clinical outcomes and reveals small correlations to CSA.

Abstract
Treatment of multilevel atherosclerotic lesions of the lower limb arteries is an acute problem in modern medicine. There is no a single treatment algorithm. Hybrid technologies are one of the possible treatment options. There are reasonable assumptions that these technologies can at least partially solve this problem. Minor trauma is an undoubted advantage of hybrid technologies. Therefore, these approaches are advisable in severe patients with various comorbidities and contraindications for traditional methods. Therefore, analysis of hybrid methods is of great interest for cardiovascular surgeons. Hybrid method is now recognized as one of the most effective and minimally traumatic treatment for patients with atherosclerotic lesions of the lower extremities.

Abstract
OBJECTIVE Present the feasibility, applicability, clinical effectiveness, and results of complicated Shamblin II or III carotid body tumors treated with a two-stage hybrid surgical approach. MATERIALS AND METHODS Retrospective, observational, cross-sectional, descriptive study of the successful treatment of 16 cases of difficult Shamblin II or III carotid body tumors, consisting of a two-stage surgical approach. We conducted a retrospective, observational, cross-sectional, descriptive study of a series of patients with complicated Shamblin II or III carotid body tumors, which we treated with a two-stage hybrid surgical procedure, in which we first placed a carotid endoprosthesis and 45 days later performed surgical resection of the tumor, following our originally published technique. This study was conducted from February, 2007 to November, 2019, in a third level care centre. RESULTS We treated 16 patients with a mean age of 50.5 years. All resided at more than 2000 meters above sea level. In all 16 a complete resection was performed. The average duration of surgery was 103.9 min, the average intraoperative bleeding was 69 ml. There were three cases of neuropraxia. The ansa cervicalis nerve had to be sectioned in three cases and there was permanent upper laryngeal nerve injury in two cases. There were no permanent cerebrovascular injuries from placement of the endoprostheses. One patient developed transient cerebral ischaemia (TIA) with no long-term sequelae. There were two cases of asymptomatic late occlusion of the endoprostheses. The average initial volume of the tumors was 54.4 cc. The average tumor volume 35 days after implant of the endoprosthesis was 30.9 cc. SYMPTOMS Presence of tumors in the neck in all cases and two cases of dysphagia. CONCLUSION This two-stage hybrid technique allowed for the complete resection of difficult Shamblin II or III carotid body tumors, with one case of TIA and two with permanent upper laryngeal nerve injuries and without mortality.

Abstract
Background: To compare the efficacy of anterior cervical discectomy and hybrid fusion (ACDHF) with short-segment plate plus self-locking, stand-alone intervertebral cages versus traditional anterior cervical discectomy and fusion (ACDF) with long-segment plate for multilevel cervical spondylotic myelopathy (MCSM). Methods: All the patients were randomly divided into two groups. 30 cases underwent ACDHF with short-segment plate and self-locking stand-alone cages (hybrid group), while the other 30 cases received ACDF with long-segment plate (control group). In patients meeting the inclusion and exclusion criteria, operation time, blood loss, postoperative drainage volume, length of stay (LOS), visual analogue scale for neck pain (VASNP) scores, Japanese Orthopaedic Association (JOA) score, and the cervical lordosis before and after the operation (5 days, 3, 6, 12 months after operation and final follow-up) were evaluated. The postoperative complications were analyzed as well. Results: All operations were performed uneventfully with followed-up. Compared with ACDF, ACDHF showed a shorter operation time, less intraoperative blood loss and postoperative drainage (p < 0.05). There were no significant difference in LOS between two groups (p ˃ 0.05). Both approaches significantly improved the JOA scores, VASNP scores and the cervical lordosis (p < 0.05). Based on Bazaz grading system, hybrid group had a lower incidence of dysphagia than control group in follow-up periods of 5 days, 3 and 6 months (p < 0.05). Conclusion: ACDF and ACDHF are both effective methods of restoring cervical lordosis following MCSM, but hybrid surgery minimizes intraoperative injury and postoperative dysphagia, making it a viable treatment option for the disorder.

Abstract
To compare the differences among constructs with one-level cervical disc arthroplasty (CDA) and two-level anterior cervical discectomy and fusion (ACDF). A retrospective study was conducted involving patients who underwent one-level CDA and two-level ACDF between June 2012 and July 2020. According to the different locations of CDA and ACDF, we divided the constructs into three types: type Ⅰa: CDA-ACDF-ACDF; type Ⅰb: ACDF-CDA-ACDF; type Ⅰc: ACDF-ACDF-CDA. The differences of clinical and radiological outcomes were evaluated. Fifty-three patients were included with 29 in type Ⅰa group, 11 in type Ⅰb group, and 13 in type Ⅰc group. After surgery, all groups showed significant improvement in apanese Orthopedic Association, Neck Disability Index, and Visual Analog Scale scores (p < 0.001). Range of motion (ROM) of the total cervical spine in type Ⅰc group decreased significantly compared with those in type Ⅰa and type Ⅰb groups (p < 0.05). No significant differences in ROM of the arthroplasty segment and the variations in ROM of the superior adjacent segment were observed among the three groups. The fusion rates of the superior ACDF segments were significantly higher at 6 and 12 months postoperatively than those of the inferior ACDF segments (p < 0.05). The clinical outcomes were similar among constructs concerning different locations of CDA and ACDF in three-level hybrid surgery. ROM of the cervical spine in type Ⅰc group decreased significantly compared with that in type Ⅰa and type Ⅰb groups. The fusion rates of superior ACDF segments were higher at early time points after surgery than those of inferior ACDF segments.

Abstract
Introduction and aims. In recent decades health care changes have accelerated enormously. Previously, by learning an effective procedure, the doctor could guarantee his patients the highest level of care for many years. Nowadays, due to the dynamics of development, the renewal cycles of the methods have been shortened, without continuous learning and training, it is already inconceivable to provide the up-to-date care required by patients. Patients and methods. Instead of vascular replacements with prosthetic grafts, which played an important role in vascular reconstructions, the primacy of endovascular techniques has become decisive. It can be significant for aortic aneurysms that can be operated with high invasiveness. The learning of catheter techniques by vascular surgeons made it possible to treat more successfully those limb-threatening cases, which are often associated with extensive vascular involvement, through the so-called hybrid operations. In addition to the increasing prevalence of diabetes worldwide, the higher proportion of critical limb ischemia and the highlighted pathogenic role of multi-resistant bacteria in the disease caused the marginaliation of the use of previously preferred prosthetic grafts. The effectiveness of the treatment of graft infections, which thus become less frequent, is improved by the use of homografts and negative pressure therapy. An effective method of preventing stroke is carotid endarterectomy, the morbidity of which is reduced by the introduction of locoregional anaesthesia allowing direct neuromonitoring. Results/conclusions. Although the acquisition and implementation of new methods has posed a continuous challenge for our specialists and doctors over the past 10 years, our achievements have made our department one of the leading vascular surgery centres in the country.

Abstract
Background Hemodynamic changes caused by hybrid surgery for brain arteriovenous malformations (bAVM) are usually related to long-term lesions from "blood stealing". There are currently no viable low-cost, noninvasive procedures for assessing cerebral perfusion in the operating room. This study aims to investigate the use of intraoperative laser speckle contrast image (LSCI) software in AVM surgery. Methods In Zhongnan Hospital of Wuhan University, 14 patients who underwent surgery with LSCI were collected. To analyze the hemodynamic features of AVM and the influence on the peripheral cortex of AVM embolization and resection, we assessed the transit time between feeding arteries and drainage veins by intraoperative digital subtraction angiography (DSA). Meanwhile, LSCI was performed at pre-embolization, post-embolization, and after complete resection of bAVM. Results In this study, the transit time of bAVM before and after embolization was compared, the transit time before embolization was significantly shorter than that after embolization (p < 0.05). We also got good visualization of relative CBF, in addition, to flow imaging in the cortical vasculature round bAVM with LSCI. The flux of post-surgery was significantly higher than pre-embolization (p < 0.01). Conclusion Hemodynamic variable assessment plays an important role in the resection of AVM in the hybrid operative room and LSCI can be used to visualize and evaluate cortical cerebral blood flow to detect pathological hyperperfusion in real-time with a good spatial-temporal resolution in a sensitive and continuous, non-invasive mode.

Abstract
Cervical fusion has been a standard procedure for treating abnormalities associated with the cervical spine. However, the reliability of anterior cervical discectomy and fusion (ACDF) has become arguable due to its adverse effects on the biomechanics of adjacent segments. One of the drawbacks associated with ACDF is adjacent segment degeneration (ASD), which has served as the base for the development of dynamic stabilization systems (DSS) and total disc replacement (TDR) devices for cervical spine. However, the hybrid surgical technique has also gained popularity recently, but its effect on the biomechanics of cervical spine is not well researched. Thus, the objective of this FE study was to draw a comparison among single-level, bi-level, and hybrid surgery with dynamic cervical implants (DCIs) with traditional fusion. Reductions in the range of motion (ROM) for all the implanted models were observed for all the motions except extension, compared to for the intact model. The maximum increase in the ROM of 42% was observed at segments C5–C6 in the hybrid DCI model. The maximum increase in the adjacent segment’s ROM of 8.7% was observed in the multilevel fusion model. The maximum von Mises stress in the implant was highest for the multilevel DCI model. Our study also showed that the shape of the DCI permitted flexion/extension relatively more compared to lateral bending and axial rotation.

Abstract
Objectives To demonstrate the feasibility and preliminary outcomes of a novel hybrid technique combining percutaneous microwave ablation and wire-assisted wedge resection for patients with multiple pulmonary metastases using intraoperative imaging. Methods We describe our technique and present a retrospective case series of 4 patients undergoing iCART at our institution between August 2018 and January 2020. Procedures were performed in a hybrid operating suite using the ARTIS Pheno cone beam computerized tomography scanner (Siemens Healthineers, Erlangen, German). Patient information included past history of malignancy as well as lesion size, depth, location, and histology result. Surgical complications and length of stay were also recorded. Results Five procedures were performed on 4 patients during the study period. One patient underwent bilateral procedures 4 weeks apart. All patients underwent at least 1 ablation and 1 wedge resection during the combined procedure. Patient ages ranged from 40 to 66 years and the majority (75%) were men. All had a past history of cancer. Lesions were treated in every lobe. Size and depth ranged from 6 to 24 mm and 21 to 33 mm, respectively, for ablated nodules and 5 to 27 mm and 0 to 22 mm, respectively, for the wedge resected nodules. Three procedures were completed uniportal and operative time ranged from 51 to 210 minutes. All cases sustained <10 mL blood loss. There were 2 intraoperative pneumothorax, 1 prevented successful completion of the ablation. One patient required a prolonged period of postoperative physiotherapy and was discharged on day 6. The other patients were discharged on postoperative day 2 or 3. All 5 histology specimens confirmed metastatic disease. Conclusions Our hybrid approach provides a minimally invasive and comprehensive personalized therapy for patients with multiple pulmonary metastases under a single general anesthetic. It provides histology-based diagnosis whilst minimizing lung tissue loss and eliminating the need for transfer from radiology to operating theatre. Emergence of ablation as a treatment for stage 1 non–small cell lung cancer and the expansion of lung cancer screening may widen the application of iCART in the future.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES Although cervical disc arthroplasty (CDA) has become a well-established and effective treatment for symptomatic cervical degeneration, many patients with multilevel disease are not good candidates for CDA at all levels. For such patients, hybrid surgery (HS)-a combination of adjacent anterior cervical discectomy and fusion (ACDF) and CDA-may be more appropriate. Given the novelty of HS and the relative dearth of studies adequately assessing short-term perioperative complications, this current study sought to assess the short-term morbidity profile of HS, differences in operative duration, length of stay (LOS), and readmission and reoperation rates and reasons relative to a 2-level ACDF cohort. METHODS All patients who underwent HS and 2-level ACDF were identified between 2011 and 2018 using a large, prospectively collected registry. Baseline patient characteristics and postoperative complications were compared using bivariate and/or multivariate analysis. RESULTS A total of 390 patients undergoing HS were identified. Two-level procedures were the most common (74.9%). Patients undergoing HS were more likely to be younger, male, and have fewer comorbidities. There were no differences between HS and 2-level ACDF in rates of any postoperative complication, transfusion, readmissions, and operative duration. However, HS had a decreased LOS (0.5 days), relative to a 2-level ACDF. HS patients had low rates of reoperation (1.28%) with 1 case for hematoma evacuation and another for revision CDA. CONCLUSIONS This study represents one of the largest cohorts of patients undergoing HS reported to date. Patients undergoing HS are not at increased risk of perioperative complications relative to a 2-level ACDF and may benefit from shorter LOS.

Abstract
The article is a review of literature dedicated to simultaneous open and endovascular (hybrid) operations in treatment of patients with chronic ischaemia of lower limbs. Despite good results of endovascular interventions, in many situations involvement of arteries below the inguinal fold and multilevel lesions are arguments in favour of performing an open operation. On the other hand, open multilevel interventions are accompanied by an increased risk of complications and mortality. Hybrid interventions appear to be a safe and efficient alternative combining advantages of two methods of treatment and making it possible to achieve an optimal outcome with a minimal surgical wound. Also discussed herein are the problems of terminology, indications for, techniques and results of treatment, providing a historical background, followed by analysing problem spots of using this technique and trends of development.

Short-term effectiveness and safety of an anatomy-conforming hybrid surgery protocol for thoracoabdominal aortic aneurysms. ANNALS OF PALLIATIVE MEDICINE 2021; 10:8762-8771. [PMID: 34488365 DOI: 10.21037/apm-21-1569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Accepted: 07/26/2021] [Indexed: 11/06/2022]
Abstract
BACKGROUND Thoracoabdominal aortic aneurysms (TAAAs) are one of the most complex aortic aneurysms to treat. Traditional open surgery for TAAAs is highly invasive and total endovascular treatment still has many limitations. Hybrid surgery offers a viable option for TAAA patients, but currently it often alters the original hemodynamics. Therefore, we have developed and applied a hybrid surgery protocol for anatomically suitable TAAA patients. Here we analyzed the short-term outcomes of these patients and evaluated the effectiveness and safety of this procedure. METHODS A new method was used to perform the required artificial revascularization of the abdominal aorta and its branches. A new visceral debranching and reconstruction approach was used to complete an anatomy-conforming open surgery. Finally, a new vascular access was used for the endovascular operation to complete the implantation of stent-grafts. The clinical data of 10 patients with TAAAs treated at our center with the anatomy-conforming hybrid technique during the period from May 2018 to June 2020 was retrospectively analyzed. The intraoperative and 30-day postoperative key indicators, including survival rates and complications, were analyzed. RESULTS The hybrid surgery was smoothly performed in all 10 patients. One patient died from non-aortic causes (sepsis/infectious toxic shock) 30 days after surgery, yielding a case-fatality rate of 10.0% (1/10). Two patients (2/10) experienced serious complications within 30 days postoperatively, including multi-organ failure due to infection in one patient and lower limb ischemia in another patient who went on to develop permanent paraplegia. No endoleak after stent implantation was noted and the blood supply of each reconstructed visceral artery was good. CONCLUSIONS Based on the short-term outcomes, the anatomy-conforming hybrid surgical protocol is safe and effective in treating TAAA patients.

Hybrid Surgery to Manage Aortic Arch Pathology. ACTA ACUST UNITED AC 2021; 57:medicina57090909. [PMID: 34577832 PMCID: PMC8471267 DOI: 10.3390/medicina57090909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/25/2021] [Accepted: 08/26/2021] [Indexed: 11/29/2022]
Abstract
Background and Objectives: Aortic arch disease is still a high-risk surgical challenge despite major advances both in surgical and anesthesiological management. A combined surgical and endovascular approach has been proposed for aortic arch disease treatment to avoid hypothermia and circulatory arrest in high-risk patients. Materials and Methods: Between June 2004 and June 2021, 112 patients were referred to our department for aortic arch surgery; 38 (33.9%) patients underwent supra-aortic debranching and endovascular treatment. Of these, 21 (55%) patients underwent type I aortic arch hybrid debranching procedure and in 17 (45%) patients a type II aortic arch hybrid debranching procedure was performed. None of the patients were emergent. Results: No intra-operative deaths were recorded. In the type I aortic arch hybrid debranching patients’ group, one patient died at home waiting the endovascular step, one developed ascending aortic dissection and another one developed a pseudoaneurysm at the site of the debranching at follow-up. In the type II aortic arch hybrid debranching patients’ group, left carotid artery branch closure was detected at follow-up in one patient. Thirty day/in-hospital rates of adverse neurological events for both the surgical and endovascular procedures were 3% for minor stroke, with no permanent neurological deficit and 0% for permanent paraplegia/paraparesis. In 100% of the cases, the endovascular step succeeded and the type Ia endoleak rate was 0%. Conclusions: Hybrid arch surgery is a valuable option for aortic arch aneurysm treatment in patients with high surgical risk. The choice of aortic arch debranching between type I or type II is crucial and depends on anatomic and clinical patient characteristics. Further larger scale studies are needed to better define the advantages of these techniques.

Abstract
OBJECTIVE The aim of the study was to evaluate the outcome of first line hybrid treatment in patients with chronic limb threatening ischemia (CLTI) and to evaluate possible predictors of primary patency (PP) loss and limb clinical improvement (LCI). METHODS This was a retrospective non-randomized study. All patients underwent one-stage hybrid common femoral artery (CFA) endarterectomy combined with an inflow and/or outflow endovascular revascularization procedure. Demographic, clinical, and lesion characteristics for each patient were reported. Primary patency analysis was performed using Kaplan-Meier life tables, and univariate and multivariate analysis was used to assess possible predictors of PP loss and clinical improvement. RESULTS Complete data were obtained from 132 patients. Patients were divided into two groups according to their Rutherford's category (RC), group 1 (Rutherford 4) and group 2 (Rutherford 5 and 6). Technical success was 98%. The overall surgical peri-operative complication rate was 8%. At a mean follow-up of 32 ± 23 months, the rate of major adverse limb events (MALE) was 30%; only the rate of major amputation between two groups was significant statistically different (p = .006). Group 1 had significantly lower amputation rate at 36 months (p = .01). The presence of high iliac peripheral artery calcium scoring system (PACCS) grade (HR 9.43, 95% CI 2.40-36.9, p = .001), the poor run-off of leg vessels (HR 0.15, 95% CI 0.02-0.92, p = .04), and undergoing CFA endarterectomy combined with outflow endovascular revascularization procedure (HR 4.25, 95% CI 1.07-16.89, p = .04) were independent predictors of PP loss, while severe iliac artery stenosis (OR 0.09, 95% CI 0.02-0.32, p = <.001) and the presence of pre-operative patent leg vessels (OR 8.03, 95% CI 2015-29.95, p = .002) were the significant independent predictors of LCI. CONCLUSION The use of hybrid first line approach in patients with CLTI is a safe and feasible technique. From the analysis of the current study, it is clear that any effort should be made to achieve as many patency leg vessels as possible in order to obtain better and longer lasting clinical outcomes.

Risk Factors for High-Grade Heterotopic Ossification After Total Disc Replacement: A Single-Center Experience of 394 Cases. Neurosurgery 2021; 89:852-861. [PMID: 34382657 DOI: 10.1093/neuros/nyab298] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 06/09/2021] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Heterotopic ossification (HO) is a common complication following total disc replacement (TDR). High-grade HO is a clinically relevant complication, however, only a few studies have evaluated risk factors for high-grade HO. OBJECTIVE To evaluate potential risk factors for HO and high-grade HO and their impact on clinical outcomes. METHODS We retrospectively reviewed patients who underwent TDR or hybrid surgery (HS) with Prestige-LP (Medtronic), Discover (Depuy), and Prodisc-C (Synthes). Clinical outcomes were assessed using Japanese Orthopaedic Association, Visual Analogue Scale, and Neck Disability Index scores. Radiological variables, including preoperative ossification, global and segmental range of motion (ROM), HO, and adjacent segment degeneration (ASD) were reviewed. RESULTS A total of 394 patients were evaluated. HO and high-grade HO occurred in 67.77% and 11.17% patients, respectively. Preoperative ossification was significantly associated with the occurrence of HO (P < .001, OR: 3.507, 95%CI: 2.211-5.562) and high-grade HO (P = .019, OR: 2.176, 95%CI: 1.137-4.166). The ROM of replacement levels and C2-7 were significantly lower in the high-grade HO group compared to those without high-grade HO: (3.80° vs 10.18°, P < .001) and (42.81° vs 54.00°, P < .001), respectively. The incidence of ASD was significantly higher in patients with high-grade HO than those without high-grade HO (22.73% vs 11.14%, P = .048). CONCLUSION Preoperative ossification was identified as a potential risk factor for HO and high-grade HO. Patients with high-grade HO had limited ROM of replacement levels and the cervical spine and had a high incidence of ASD compared to those without high-grade HO.

Concomitant Embolization and Microsurgical Resection of a Giant, Hypervascular Skull Base Meningioma: 2-Dimensional Operative Video. Oper Neurosurg (Hagerstown) 2021; 21:E97-E98.

Abstract
Some skull base tumors can be extremely hypervascular, incorporating multiple vascular territories and demonstrating arteriovenous shunting. Devascularization is a critical step undertaken early in meningioma surgery, necessary before the debulking that is required in skull base tumors. While devascularization can often be achieved with appropriate approach selection, bony drilling, and microsurgical cautery, preoperative embolization of meningiomas has an invaluable role in selected cases.1,2 Embolization, however, does have added risk, magnified in large tumors by the potential infarction with subsequent edema that can potentially lead to acute deterioration and neurosurgical emergency. Hence, to achieve devascularization of an extremely vascular tumor, embolization and surgical resection should be performed concomitantly, as one operation, in which embolization might be the first stage, or might be performed after the craniotomy flap is raised, if necessary.3 Naturally, this requires the multifaceted neurosurgical expertise of embolization and microsurgical resection, and the facility to perform such. We present a case of a giant, hypervascular, radiation-induced, skull base meningioma with internal and external carotid artery supply in a young patient with deteriorating vision in his only eye. Selective embolization of the internal maxillary, middle meningeal, and middle cerebral artery blood supplies was performed. Microsurgical interruption of the ethmoidal artery blood supply was then performed. This hybrid approach safely and effectively devascularized the tumor and allowed for a complete resection of this high-risk tumor4 while minimizing risk to the ophthalmic artery and optic nerve. The patient was consented for surgery.

Abstract
INTRODUCTION Concurrent stenting of complex iliac lesions during infrainguinal bypasses can increase the complexity of a case and impact outcomes. OBJECTIVE Our aim was to evaluate the effect of inflow stenting of TASC-II C, D iliac lesions on femoropopliteal bypass patency. METHODS A retrospective observational cohort study of patients who underwent femoropopliteal bypass with TASC-II C, D iliac artery stenting (hybrid group) or without inflow lesions (non-hybrid group) was conducted. After propensity score matching, 120 patients were included in the non-hybrid group and 60 patients in the hybrid one. The median follow-up was 432 (193; 1313) days in the hybrid group and 472 (196; 1376) days in the non-hybrid group (p = 0.94). RESULTS No significant differences were found between the groups in 30-day morbidity and serious adverse events. At 3 years, primary and secondary bypass patency for the hybrid group and non-hybrid group were 62.2% versus 59.9% (p = 0.36) and 63.7% versus 64.3% (p = 0.077), respectively. The primary patency of the iliac stents in patients of the hybrid group was 95% at 3 years. The estimated hazard ratio for primary patency for hybrid versus non-hybrid was 0.77, with 90% CI: 0.50-1.21; the noninferiority upper bound being 1.31, which corresponds to a 10% additive noninferiority margin for probabilities. The 3 years of freedom from amputation in patients with chronic limb-threatening ischemia was 94.1% and 75.0% in the hybrid and non-hybrid groups, respectively (p = 0.09). CONCLUSION The outcomes of the femoropopliteal bypass in hybrid surgery supplemented with stenting of TASC-II C, D iliac lesions was similar to femoropopliteal bypass with intact inflow arteries.

Abstract
Presented herein is a review of the literature dedicated to the method of visceral debranching, i. e., switching of the visceral and renal branches of the abdominal aorta to its intact portion, using synthetic vascular prostheses as the first stage of hybrid surgical treatment of thoracoabdominal aortic aneurysms prior to endovascular aortic aneurysm repair. This is accompanied and followed by describing the history of the problem, operative technique, results of studies, as well as the data from registries and meta-analyses. Also discussed are the main complications of the method and measures of their prevention. We conclude that hybrid surgery of the thoracoabdominal portion of the aorta is a promising method in a particular cohort of patients, especially those at high surgical risk of 'open' aortic surgery.

Abstract
Managing type B aortic dissection (TBAD) involving Kommerell's diverticulum (KD), aberrant right subclavian artery (ARSA), and isolated left vertebral artery (ILVA), is extremely challenging. As treatment, we described a one-stage hybrid technique combined with thoracic endovascular aortic repair (TEVAR) with open surgery through a supraclavicular incision. A 57-year-old man with TBAD and the three anomalies successfully underwent hybrid TEVAR. A side-to-side artificial bypass between the ARSA and the right common carotid artery was established through a right supraclavicular incision before TEVAR. The release of the stent-graft was designed from the distal aortic ostium to the left common carotid artery (LCCA) to cover the ILVA, ARSA, and left subclavian artery (LSA). Then, the ILVA and LSA were transposed to the LCCA through a left supraclavicular incision. Intraoperative angiography confirmed complete false lumen exclusion and KD, with all branches patent and without endoleaks. Computed tomography angiography 7 days and 1 year postoperatively demonstrated well-perfused ARSA, LSA, and ILVA, and a fully expanded stent-graft with no endoleaks, migration, disconnection, or stenosis. TBAD involving KD, ARSA, and ILVA in one case is rare. This is the first report to treat this pathology with a one-stage supraclavicular hybrid procedure.

Abstract
OBJECTIVE To present our experience in the treatment of severe patients with mega aorta syndrome. MATERIAL AND METHODS There were 49 patients with mega aorta syndrome for the period from May 2015 to March 2021. All patients underwent total aortic replacement from sinotubular junction (with staged aortic root repair, if necessary) to abdominal aorta bifurcation. All surgeries were elective. All patients were divided into two groups: group I (n=33; 67.3%) - staged replacement, group II (n=16; 32.7%) - one-staged replacement of the aorta via thoracophrenolumbotomy. The primary endpoints were mortality, perioperative parameters and complications. We also analyzed long-term freedom from aortic redo surgery and survival rate. RESULTS Both groups were comparable by pre-, intra- and postoperative parameters. The interval between surgeries for staged approach was 7.1±2.3 months. Rehabilitation time considering two stages was longer in group I (13±2 vs. 5.5±1.1 months, p=0.0001). Between-stage mortality rate was 12% (n=4). Intraoperative mortality was absent in both groups. In-hospital mortality was 3% and 12% (p=0.25), overall mortality with between-stage interval - 10.2% and 12% (p=1.000), respectively. The follow-up period was similar (18±22.7 (range 1-71) and 23.3±19.1 (range 1-51) months, respectively (p=0.63)). In group I, 1-year, 3-year and 5-year survival rate considering between-stage mortality was 89% (95% CI 78-100%), 77.1% (95% CI 60.1-98.8%), 77.1% (95% CI 60.1-98.8%), respectively. In group II, 1-year and 3-year survival rate was 86.5% (95% CI 70.5-100%), plog-rank=0.88. Overall freedom from redo surgery was 92.9% (95% CI 80.3-100%) vs. 90.9% (95% CI 75.4-100%), plog-rank=0.072. CONCLUSION One-stage total aortic replacement via thoracophrenolumbotomy is safe surgical treatment for mega aorta syndrome, especially in young patients with low surgical risk. Favorable outcomes may be expected in specialized centers with extensive experience in aortic surgery. Compared to staged approach, total aortic replacement eliminates the risks of between-stage aortic rupture. Therefore, it is a worthy alternative to other methods.

Abstract
Here, we report a case of an infectious pseudoaneurysm at the root of the innominate artery, compressing the trachea, that resulted in massive hemorrhage due to rupture of the innominate artery. The patient, a 31-year-old man, had complained of persistent fever for 40 days and severe dyspnea for 1 week. Contrast-enhanced computed tomography imaging of neck and thorax showed a pseudoaneurysm originating from the root of the innominate artery that was severely compressing the main trachea. A hybrid surgery strategy was applied. We first implanted a covered stent in the root of the innominate artery. Then, we performed a left-to-right carotid−carotid bypass with a great saphenous vein graft. Finally, we performed a median thoracotomy in which both the pseudoaneurysm and the previously implanted covered stent were successfully extracted. The patient lost strength in the right upper limb muscle on postoperative day 2 but recovered to baseline strength after 3 months. A hybrid surgical technique may represent a practical solution for such conditions.

Abstract
Background: Anterior cervical discectomy and fusion (ACDF) still represent the mainstream surgical approach in the treatment of degenerative cervical Degenerative Disc Disease (DDD), being a loss of mobility at the treated segment and adjacent segment diseases well-known complications. To overcome those complications, hybrid surgery (HS) incorporating ACDF and cervical disk arthroplasty is increasingly performed for DDD. Methods: We retrospectively reviewed the clinical, surgical, and outcome data of 62 consecutive patients (male/female, 29/37) harboring cervical disk herniation with or without osteophytes, with radiculopathy with or without myelopathy, who underwent a cervical discectomy on two or more levels with the anterior approach with at least one disk prosthesis along with cage and plate or O Profile screwed plate. Results: All the patients improved regardless of the cervical construct used. No significant relationship between different kind of prostheses as well as their surgical level, the number and the site of the cages (screwed and/or plated) was found out concerning immediate stability, dynamic prosthesis effectiveness, and clinical improvement in all the patients up to the maximum follow-up. Conclusions: Although the optimal surgical technique for cervical DDD remains controversial, HS represents a safe and effective procedure in selected patients with multilevel cervical DDD, as demonstrated by biomechanical and clinical studies and the present series. Some technical aspects should be considered when dealing with this procedure, like the drilling of the endplate, and some radiological findings have to be detected because potentially predictive of future misplacement.

Abstract
OBJECTIVES To compare the efficacy and prognosis of one-stop hybrid surgery using the elephant trunk procedure for treatment of complex Stanford type B aortic dissection. METHODS We retrospectively analyzed patients who underwent surgical treatment from January 2014 to July 2019. The patients were divided into those who underwent the elephant trunk procedure (n = 10) and those who underwent one-stop hybrid surgery (n = 10). The cardiopulmonary bypass time, mechanical ventilation time, length of hospital stay, and red blood cell usage were compared between the two groups. All patients' 3-month postoperative aortic computed tomography angiography (CTA) findings were also reviewed. RESULTS The cardiopulmonary bypass time, mechanical ventilation time, and length of hospital stay were significantly shorter and red blood cell usage was significantly lower in the one-stop hybridization group. The aortic cross-clamp time was not significantly different between the two groups. Aortic CTA review after hybrid surgery showed that the true lumen of the descending aorta was almost completely restored at 3 months. CONCLUSION One-stop hybrid surgery effectively alleviated the occlusion of the aortic dissection, prevented the need for additional surgery, and expanded the indications for covered-stent endovascular repair.

Abstract
Objective For carotid artery stenosis with a large amount of vulnerable plaque in a wide range, we performed a hybrid surgery combining carotid endarterectomy (CEA) and carotid artery stenting (CAS), and report the results of treatment. Methods Surgical treatment for carotid artery stenosis in 216 patients was performed between January 2016 and June 2018. Of these, 15 patients were treated in a hybrid operating room because both CEA and CAS were judged to be risky. We treated these patients with preparation of stenting for remote lesions far from the CEA arterial incision. The perioperative treatment results were retrospectively examined. Results Of the 15 patients treated in a hybrid operating room, 10 were stented after CEA. All these cases were treated by retrograde stent placement in the proximal common carotid artery (CCA). Treatment was completed in all patients, and no cerebral infarction, myocardial infarction, or death was observed in the perioperative period. There were no cases of additional neurological events during the follow-up period, but asymptomatic restenosis was observed in one patient. Conclusion Hybrid surgery combining CEA and CAS was considered to be an effective treatment for carotid artery stenosis with a large amount of vulnerable plaque.

Abstract
Objective: This work aims to present our experience of patients with complex cerebral aneurysm treated with a hybrid approach: superficial temporal artery–middle cerebral artery (STA–MCA) bypass in combination with endovascular exclusion of the aneurysm. Method: Patients with aneurysms deemed unclippable and uncoilable were included. All patients were treated with a hybrid approach. After STA–MCA bypass, the parent artery was temporarily occluded. If the intraoperative motor evoked potential (MEP) and somatosensory evoked potential (SEP) waveforms remain normal and last for 30 min, the aneurysm and te parent artery will be embolized permanently with detachable balloons or coils. Results: A total of 20 patients with 22 aneurysms were included in this study. There were 13 women and 7 men, with an average age of 42.5 years. Intraoperative angiography showed the good patency of all the STA grafts, and neither SEP nor MEP abnormalities were detected. After the parent artery and the aneurysm were occluded, the intraoperative angiography showed an immediately successful exclusion of the aneurysm in 20 aneurysms and immediate contrast stasis in two. All patients recovered uneventfully without ischemic or hemorrhagic complication. Angiography at 6-month follow-up showed the total obliteration in 20 aneurysms. Two aneurysms showed residuals and were recoiled. All STA grafts showed a good patency, and the mean graft flow was 124.2 ml/min. Conclusion: STA–MCA bypass in combination with endovascular exclusion is an appropriate option for patients with complex cerebral aneurysms that are not amenable to direct surgical clipping or endovascular embolization.

A modified frozen elephant trunk hybrid device to facilitate supra-aortic trunk anastomosis. J Card Surg 2020; 36:371-373. [PMID: 33225461 DOI: 10.1111/jocs.15208] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 10/09/2020] [Accepted: 10/22/2020] [Indexed: 11/30/2022]
Abstract
Reimplantation of the supra-aortic vessels can be challenging with Thoraflex Hybrid. A device modification made the vessel lengths more appropriate and the position of the neo-vessels in the chest avoided malpositioning and kinking and facilitated sternum closure; this may improve operating times as well as allowing complete and continuous cerebral trivascular perfusion and corrects positioning of the intrathoracic vessels.

Abstract
Objective: This study aims to evaluate the chronological size changes of the prosthetic graft in the aortic arch, which is used as a landing zone for a subsequent stent grafting in hybrid aortic surgery. Materials and Methods: Eighty-five patients who underwent total aortic arch replacement followed by computed tomography follow-up for at least 30 months after the surgery were included in the study. Results: Prosthetic grafts used were Hemashield (Maquet, Rastatt, Germany), J-Graft (Japan Lifeline Inc., Tokyo, Japan) and Triplex (Terumo, Tokyo, Japan). There was an initial increase in diameter compared to package size after implantation (Hemashield, 1.04±0.035 vs. J-Graft, 1.06±0.027 vs. Triplex, 1.04±0.023, p=0.13). Significant difference in graft dilation ratio was observed in Triplex (1.18±0.062) at long-term compared to Hemashield (1.07±0.052, p<0.001) and J-Graft (1.10±0.071, p<0.001). Multivariate analysis showed that age (r=0.002; 95% confidence interval [CI], 0.0001–0.0037; p=0.035), knitted-type prosthesis (r=0.089; 95% CI, 0.0610–0.1163; p<0.0001), and prevalence of cerebral vascular disease (r=0.038; 95% CI, 0.0030–0.0732; p=0.034) were independently associated with graft dilation after surgery. Conclusion: Prosthetic graft selection and appropriate sizing of the stent graft should be considered for each individual undergoing hybrid aortic surgery to maintain sufficient oversizing of the stent graft.

A Treatment Option for Symptomatic Chronic Complete Internal Carotid Artery Occlusion: Hybrid Surgery. Front Neurosci 2020; 14:392. [PMID: 32410953 PMCID: PMC7199050 DOI: 10.3389/fnins.2020.00392] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2019] [Accepted: 03/30/2020] [Indexed: 11/13/2022] Open
Abstract
Background Internal carotid artery occlusion (ICAO) is a relatively uncommon but important cause of transient ischemic attack and cerebral infarction. The majority of cases of symptomatic ICAO requires surgical treatment. In this study we performed an investigation of the efficacy and safety of hybrid surgery which is a surgical method for symptomatic chronic complete ICAO. Methods Fifty-five patients with symptomatic chronic ICAO treated by hybrid surgery from 2016 to 2019 were included. We recorded and analyzed the patients’ clinical characteristics, angiographic data, recanalization rate, complications, and outcomes. Catheter angiography or computed tomography angiography was used to assess the patency of the recanalized ICA during follow-up. Results The total success rate of recanalization was 78.2% (43/55). The occlusions were significantly shorter in the success than failure group (5.40 ± 1.50 vs. 7.56 ± 0.99 cm, respectively; P < 0.001). The median duration of ICA occlusion was significantly shorter in the success than failure group (90 vs. 200 days, respectively). The success rates of distal ICA recanalization at the petrous segment or below, cavernous segment, and clinoid segment or above were 100, 33.3, and 14.3%, respectively (P < 0.001). Multivariate analysis showed that the level of distal ICA reconstitution was the only factor affecting the recanalization success rate. Periprocedural complications included hyperperfusion syndrome (n = 1) and laryngeal nerve injury (n = 1). ICA reocclusion occurred in one patient (2.3%). Significant postoperative improvement in symptoms was observed in the success group, with a median modified Rankin scale score of 0 at the 3-month follow-up compared with before recanalization (median, 1) (P<0.001). Conclusion Hybrid surgery might be safe and effective for patients with symptomatic chronic complete ICAO. The level of distal ICA reconstitution is a predictor of successful recanalization in hybrid operations.

Optimization of Three-Level Cervical Hybrid Surgery to Prevent Adjacent Segment Disease: A Finite Element Study. Front Bioeng Biotechnol 2020; 8:154. [PMID: 32195235 PMCID: PMC7064443 DOI: 10.3389/fbioe.2020.00154] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Accepted: 02/14/2020] [Indexed: 12/23/2022] Open
Abstract
Hybrid surgery (HS) allows surgeons to tailor fusion and arthroplasty in the treatment of multiple-level cervical disc degeneration. However, the decision making of selecting either ACDF or ADR for each level in three-level HS remains controversial and has not been fully investigated. This study was aimed to optimize three-level cervical hybrid constructs by systematically investigating their biomechanical properties and their effect on adjacent levels. A finite element model of cervical spine (C2–C7) was developed, and eight C3–C6 surgical models including six HS were constructed. The range of motion (ROM) in flexion, extension, lateral bending, and axial rotation under 2.0 Nm moments with 30 N follower load were simulated. The von Mises stress, strain energy at the adjacent intervertebral disc (IVD) and force at the adjacent facet were calculated. The ROM of the hybrid constructs and adjacent levels was close to that of the intact spine. HS with arthroplasty performed at C5-6 had better performance in terms of ROM reduction at the inferior adjacent level (C6-7). Moreover, C-D-D and 3ADR had best performance in reducing the von Mises stress and strain energy at C6-7. All HS reduced the facet burden at both C2-3 and C6-7 levels. However, the major drawback of HS revealed here is that the effect of C6-7 protection is at the cost of increased C2-3 IVD burden. In conclusion, we recommend C-D-D and 3ADR for patient with C3–C6 disc degeneration without predisposing C2-3 condition. C-C-D could be a good alternative with a lower medical cost. This analysis guides the decision making in three-level cervical HS before future cadaver studies or human clinical trials.

Abstract
To investigate the outcomes and reliability of hybrid surgery (HS) versus anterior cervical discectomy and fusion (ACDF) for the treatment of multilevel cervical spondylosis and disc diseases.Hybrid surgery, combining cervical disc arthroplasty (CDA) with fusion, is a novel treatment to multilevel cervical degenerated disc disease in recent years. However, the effect and reliability of HS are still unclear compared with ACDF.To investigate the studies of HS versus ACDF in patients with multilevel cervical disease, electronic databases (Medline, Embase, Pubmed, Cochrane library, and Cochrane Central Register of Controlled Trials) were searched. Studies were included when they compared HS with ACDF and reported at least one of the following outcomes: functionality, neck pain, arm pain, cervical range of motion (ROM), quality of life, and incidence of complications. No language restrictions were used. Two authors independently assessed the methodological quality of included studies and extracted the relevant data.Seven clinical controlled trials were included in this study. Two trials were prospective and the other 5 were retrospective. The results of the meta-analysis indicated that HS achieved better recovery of NDI score (P = 0.038) and similar recovery of VAS score (P = 0.058) compared with ACDF at 2 years follow-up. Moreover, the total cervical ROM (C2-C7) after HS was preserved significantly more than the cervical ROM after ACDF (P = 0.000) at 2 years follow-up. Notably, the compensatory increase of the ROM of superior and inferior adjacent segments was significant in ACDF groups at 2-year follow-up (P < 0.01), compared with HS.The results demonstrate that HS provides equivalent outcomes and functional recovery for cervical disc diseases, and significantly better preservation of cervical ROM compared with ACDF in 2-year follow-up. This suggests the HS is an effective alternative invention for the treatment of multilevel cervical spondylosis to preserve cervical ROM and reduce the risk of adjacent disc degeneration. Nonetheless, more well-designed studies with large groups of patients are required to provide further evidence for the benefit and reliability of HS for the treatment of cervical disk diseases.

Abstract
Purpose: To investigate the utilization of local anesthesia or peripheral nerve block with monitored anesthesia care (LPMAC) and its impact on the perioperative outcomes of hybrid lower extremity revascularization (LER) compared with general anesthesia (GA). Materials and Methods: A search of the ACS-NSQIP database between 2005 and 2017 identified 9430 patients who underwent hybrid LER for peripheral artery disease. Excluding 449 ineligible cases left 8981 hybrid LER patients for analysis. The patients were dichotomized based on the anesthetic technique: 8631 (96.1%) GA and 350 (3.9%) LPMAC. The GA patients were matched 3:1 based on propensity scores to patients in the LPMAC group based on gender, age, race, functional status, transfer status, chronic obstructive pulmonary disease (COPD), dialysis status, American Society of Anesthesiologists (ASA) class, emergent surgery, preoperative sepsis, indication, and type of open and endovascular procedure. Outcomes including complications, mortality, procedure time, and hospital length of stay were compared between the matched groups (801 GA vs 267 LPMAC). Results: Comparing the unmatched groups, those treated under LPMAC were older (72.7±9 vs 68±8.4 years, p<0.001) and had higher rates of COPD (24.3% vs 17%, p=0.001), dialysis dependence (8.1% vs 4.2%, p=0.002), preoperative sepsis (6.6% vs 4.2%, p=0.029), and ASA class ≥IV (29.1% vs 24.1%, p=0.036) than in the unmatched GA cohort. In the matched comparison, LPMAC was associated with lower overall morbidity (25.5% vs 32.3%, p=0.042) and shorter operating time (202.7±98 vs 217.7±102 minutes, p=0.034) compared with GA. The rate of myocardial infarction was lower (1.1% vs 2.4%) and ventilator use for >48 hours was less frequent (0.4% vs 2.6%) for LPMAC patients, though statistical significance was not reached. There was no difference in mortality or hospital length of stay. Conclusion: LPMAC is an infrequent anesthetic technique for hybrid LER and is primarily used for patients with a high burden of comorbidities. LPMAC is associated with reduced overall morbidity and operating time. Further studies are needed to identify which patients undergoing hybrid LER benefit most from LPMAC.

Abstract
A safe technique for entry incisions and closure in stage 5 retinopathy of prematurity (ROP) surgery is being described. Three 23G clear corneal incisions are made which allow for safe and snug entry of 25G calibrated infusion and 25G instruments for performing lensectomy, membrane removal and vitrectomy. At the end of surgery, air is injected and corneal entries are hydrated for sutureless closure. The technique was performed in 50 eyes of 36 children with stage 5 ROP. The hybrid technique ensured safe entry and exit with stable anterior chamber during surgery. None of the cases developed retinal breaks during surgical entry nor had any complications such as hypotony, flat anterior chamber, hyphaema or corneal edema in post operative period. Clear corneal entry using 23G incisions for 25G instrument access is a safe and effective technique for performing lensectomy and vitrectomy with sutureless closure in cases with stage 5 ROP.
