Surgical management and outcomes of coronary artery involvement secondary to acute type A aortic dissection: a retrospective cohort study. J Thorac Dis 2023; 15:6436-6446. [PMID: 38249883 PMCID: PMC10797399 DOI: 10.21037/jtd-23-990] [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: 06/22/2023] [Accepted: 10/20/2023] [Indexed: 01/23/2024]
Abstract
Background Coronary artery involvement (CAI) remains a fatal comorbidity in the context of acute type A aortic dissection (ATAAD). We evaluated the impact of CAI on the perioperative and short-term outcomes of patients with ATAAD who underwent total arch replacement (TAR) and frozen elephant trunk (FET) implantation and shared our surgical management experience with the involved coronary artery. Methods In this retrospective cohort study, a total of 204 patients with ATAAD between June 2019 and December 2021 were enrolled and divided into the CAI group (n=67) and the non-CAI group (n=137). The characteristics of CAI lesions were described according to the Neri classification. Univariable and multivariable analyses were used to identify independent risk factors for in-hospital mortality. Survival analysis was performed using the Kaplan-Meier method and compared using the log-rank test. Results Patients in the CAI group had a longer intraoperative duration of cardiopulmonary bypass (CPB) and cross-clamp, and experienced longer mechanical ventilation time and intensive care unit stays postoperatively. Regarding perioperative outcomes, the prevalence rates of new-onset continuous renal replacement therapy requirement (23.9% vs. 10.2%, P=0.01) and in-hospital mortality (17.9% vs. 7.3%, P=0.02) were higher in the CAI group. Coronary artery malperfusion (CAM) was an independent risk factor for in-hospital mortality. Short-term survival analysis was similar between the two groups (P=0.146). Conclusions For patients with ATAAD undergoing TAR and FET implantation, concomitant CAI may complicate surgery and increase in-hospital morbidity and mortality. CAM secondary to CAI was identified as an independent risk factor. However, short-term survival after hospital discharge was comparable between the two groups. Coronary ostium repair is quick and operable for both type A and type B lesions, while optimal management still warrants further investigation.

Reconstruction and Validation of Arterial Geometries for Computational Fluid Dynamics Using Multiple Temporal Frames of 4D Flow-MRI Magnitude Images. Cardiovasc Eng Technol 2023; 14:655-676.

Abstract
PURPOSE Segmentation and reconstruction of arterial blood vessels is a fundamental step in the translation of computational fluid dynamics (CFD) to the clinical practice. Four-dimensional flow magnetic resonance imaging (4D Flow-MRI) can provide detailed information of blood flow but processing this information to elucidate the underlying anatomical structures is challenging. In this study, we present a novel approach to create high-contrast anatomical images from retrospective 4D Flow-MRI data. METHODS For healthy and clinical cases, the 3D instantaneous velocities at multiple cardiac time steps were superimposed directly onto the 4D Flow-MRI magnitude images and combined into a single composite frame. This new Composite Phase-Contrast Magnetic Resonance Angiogram (CPC-MRA) resulted in enhanced and uniform contrast within the lumen. These images were subsequently segmented and reconstructed to generate 3D arterial models for CFD. Using the time-dependent, 3D incompressible Reynolds-averaged Navier-Stokes equations, the transient aortic haemodynamics was computed within a rigid wall model of patient geometries. RESULTS Validation of these models against the gold standard CT-based approach showed no statistically significant inter-modality difference regarding vessel radius or curvature (p > 0.05), and a similar Dice Similarity Coefficient and Hausdorff Distance. CFD-derived near-wall hemodynamics indicated a significant inter-modality difference (p > 0.05), though these absolute errors were small. When compared to the in vivo data, CFD-derived velocities were qualitatively similar. CONCLUSION This proof-of-concept study demonstrated that functional 4D Flow-MRI information can be utilized to retrospectively generate anatomical information for CFD models in the absence of standard imaging datasets and intravenous contrast.

Abstract
Aortic dissection (AD) is a severe cardiovascular condition that could have negative consequences. Our study employed a prospective design and examined preoperative, perioperative, and postoperative data to evaluate the effects of gender on various medical conditions. We looked at how gender affected the results of aortic dissection (AD). In contrast to female patients who had more systemic hypertension (p=0.031), male patients had higher rates of hemopericardium (p=0.003), pulmonary hypertension (p=0.039), and hemopericardium (p=0.003). Dobutamine administration during surgery significantly raised the mortality risk (p=0.015). There were noticeably more women patients (p=0.01) in the 71 to 80 age group. Significant differences in age (p=0.004), eGFR at admission (p=0.009), and eGFR at discharge (p=0.006) were seen, however, there was no association between gender and mortality. In conclusion, our findings highlight that gender may no longer be such an important aspect of aortic dissection disease as we previously thought, and this information could have an important contribution for surgeons as well as for anesthesiologists involved in the management of acute aortic dissection.

J Cardiothorac Surg 2022; 17:184. [PMID: 35982501 PMCID: PMC9389841 DOI: 10.1186/s13019-022-01946-z] [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: 01/11/2022] [Accepted: 08/15/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Perioperative coagulopathy and intractable bleeding are severe complications in acute type A aortic dissection (ATAAD) repair surgery. Mediastinal packing with delayed sternal closure (DSC) is a commonly adapted technique to stabilize the hemorrhagic tendency. This retrospective study aims to investigate the early and late outcomes and risk factors in patients who underwent DSC procedure during ATAAD repair surgery. METHODS This study investigated 704 consecutive patients who underwent ATAAD repair at this institution between January 2007 and September 2020. These patients were dichotomized into the DSC (n = 109; 15.5%) and primary sternal closure (PSC) groups (n = 595; 84.5%). The clinical features, surgical information, postoperative complications, 5-years cumulative survival, and freedom from reoperation rates were compared. A multivariate logistic regression analysis was used to identify the independent risk factors for patients who underwent DSC. RESULTS The DSC group showed a higher rate of hemopericardium and preoperative malperfusion, and was associated with longer cardiopulmonary bypass and aortic clamping times and a higher rate of intraoperative extracorporeal membrane oxygenation (ECMO) support. The DSC group showed higher blood transfusion volumes and rate of reexploration for bleeding after surgery. However, the in-hospital mortality rates (17.4% vs. 13.3%; P = 0.249), 5-year survival rates (66.9% vs. 68.2%; P = 0.635), and freedom from reoperation rates (89.1% vs. 82.5%; P = 0.344) were comparable between the DSC and PSC groups. Multivariate analysis revealed that hemopericardium, preoperative malperfusion, and intraoperative ECMO support were risk factors for implementing DSC. CONCLUSIONS DSC is an efficient life-saving technique to stabilize patients with intractable bleeding after undergoing ATAAD repair surgery, which leads to acceptable short- and long-term outcomes. Patients who were at risk for intractable bleeding should have early decision-making for implementing DSC.

Transfusion in Root Replacement for Aortic Dissection: STS Adult Cardiac Surgery Database Analysis. Ann Thorac Surg 2022; 114:2149-2156. [PMID: 35452664 DOI: 10.1016/j.athoracsur.2022.03.068] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 03/09/2022] [Accepted: 03/22/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND Transfusion in acute aortic syndromes has been studied in a limited fashion. We sought to describe contemporary transfusion practice for root replacement in acute (Stanford) type A aortic dissection (ATAAD). METHODS The STS Adult Cardiac Surgery Database was interrogated to identify patients who underwent primary aortic root replacement for ATAAD (July 2014 - June 2017). Patients (n = 1558) were stratified by type of root replacement. Multivariate regression was used to determine those variables associated with transfusion and postoperative morbidity. RESULTS Transfusion was required in 90.5% of cases (n = 1410). Operative mortality for all patients was 17.3% (261 deaths). Intraoperative red blood cell (RBC) transfusion portended reduced short-term survival (odds ratio {OR} 2.00, p = 0.025). Massive postoperative transfusion was associated with prolonged ventilation (OR 13.47, p < 0.001), sepsis (OR 4.13, p < 0.001), and new dialysis-dependent renal-failure (OR 2.43, p < 0.001). Females were more likely to require transfusion (OR 3.03, p < 0.001), as were patients who had coronary bypass (OR 1.57, p = 0.009), and those in shock (OR 2.27, p < 0.001). Valve-sparing aortic root replacement (VSARR) was associated with reduced transfusion requirements vs. composite roots. Institutional case volume was not appreciably correlated with transfusion. CONCLUSIONS Most patients undergoing root replacement for aortic dissection require blood products. Composite root replacement is associated with a greater likelihood of transfusion than a valve-sparing operation. Transfusion independently foreshadows greater operative mortality.

A Novel Sutureless Integrated Stented (SIS) Graft Prosthesis for Type A Aortic Dissection: A Pilot Study for a Prospective, Multicenter Clinical Trial. Front Cardiovasc Med 2022; 8:806104. [PMID: 35211519 PMCID: PMC8860904 DOI: 10.3389/fcvm.2021.806104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Accepted: 12/06/2021] [Indexed: 11/21/2022] Open
Abstract
Aims Various kinds of surgical strategies and prostheses have been advocated to improve short-term and long-term outcomes in type A aortic dissection (TAAD). Large-scale repair of the pathological aorta is hard to generalize due to complex procedures. We aimed to investigate the performance, effectiveness and safety of a novel Sutureless Integrated Stented (SIS) graft prosthesis in TAAD patients undergoing total arch replacement (TAR) and frozen elephant trunk (FET) implantation surgery. Methods All patients admitted to Fuwai Hospital were prospectively screened. Urgent or scheduled surgery was arranged for eligible patients. The primary endpoint was operative mortality. Key secondary endpoints included stroke, spinal cord injury, unexpected aortic reoperation, and 1-year survival. Discharged patients were followed up with computed tomography angiography and transthoracic echocardiography at 3 months, 6 months, and 1 year after surgery. Performance, effectiveness and safety analyses were performed in those patients. Results Between August 1 and September 3, 2020, ten TAAD patients were enrolled in this study and successfully implanted with the SIS graft prosthesis. The median (IQR) age was 56.50 (43.75, 66.75) years (range from 31 to 75), and seven patients were male (70.0%). All patients underwent ascending aorta replacement + TAR + FET and additional procedures when necessary. The median (IQR) operation time, cardiopulmonary bypass time and cross clamp time were 270.50 (218.50, 312.50), 110.00 (88.00, 125.75), 69.50 (51.25, 82.75) min, respectively. Of note, the median (IQR) circulatory arrest time was 9.00 (8.00, 9.00) min (range from 4 to 12). The median (IQR) lowest nasopharyngeal temperature was 26.75 (25.98, 27.67) °C. Follow-up was 100% completed. During the 1-year follow-up, no patients died, no severe adverse events occurred, and rate of freedom from aortic reintervention was 100%. Conclusions The SIS graft prosthesis was implanted in a novel sutureless way, which simplified the surgical procedure, shortened the circulatory arrest time and avoided deep hypothermia. The preliminary clinical outcomes and follow-up outcomes demonstrated the effectiveness and safety of this prosthesis. A large-scale trial is being conducted to further assess these findings.

Incidence- and In-hospital Mortality-Related Risk Factors of Acute Kidney Injury Requiring Continuous Renal Replacement Therapy in Patients Undergoing Surgery for Acute Type a Aortic Dissection. Front Cardiovasc Med 2021; 8:749592. [PMID: 34888362 PMCID: PMC8650701 DOI: 10.3389/fcvm.2021.749592] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 09/27/2021] [Indexed: 02/05/2023] Open
Abstract
Background: Few studies on the risk factors for postoperative continuous renal replacement therapy (CRRT) in a homogeneous population of patients with acute type A aortic dissection (AAAD). This retrospective analysis aimed to investigate the risk factors for CRRT and in-hospital mortality in the patients undergoing AAAD surgery and to discuss the perioperative comorbidities and short-term outcomes. Methods: The study collected electronic medical records and laboratory data from 432 patients undergoing surgery for AAAD between March 2009 and June 2021. All the patients were divided into CRRT and non-CRRT groups; those in the CRRT group were divided into the survivor and non-survivor groups. The univariable and multivariable analyses were used to identify the independent risk factors for CRRT and in-hospital mortality. Results: The proportion of requiring CRRT and in-hospital mortality in the patients with CRRT was 14.6 and 46.0%, respectively. Baseline serum creatinine (SCr) [odds ratio (OR), 1.006], cystatin C (OR, 1.438), lung infection (OR, 2.292), second thoracotomy (OR, 5.185), diabetes mellitus (OR, 6.868), AKI stage 2-3 (OR, 22.901) were the independent risk factors for receiving CRRT. In-hospital mortality in the CRRT group (46%) was 4.6 times higher than in the non-CRRT group (10%). In the non-survivor (n = 29) and survivor (n = 34) groups, New York Heart Association (NYHA) class III-IV (OR, 10.272, P = 0.019), lactic acidosis (OR, 10.224, P = 0.019) were the independent risk factors for in-hospital mortality in patients receiving CRRT. Conclusion: There was a high rate of CRRT requirement and high in-hospital mortality after AAAD surgery. The risk factors for CRRT and in-hospital mortality in the patients undergoing AAAD surgery were determined to help identify the high-risk patients and make appropriate clinical decisions. Further randomized controlled studies are urgently needed to establish the risk factors for CRRT and in-hospital mortality.

[PMID: 34674651 PMCID: PMC8529736 DOI: 10.1186/s12872-021-02324-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 10/14/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To investigate the risk factors for mortality in patients with acute kidney injury requiring continuous renal replacement therapy (AKI-CRRT) after cardiac surgery. METHODS In this retrospective study, patients who underwent AKI-CRRT after cardiac surgery in our centre from January 2015 to January 2020 were included. Univariable and multivariable analyses were performed to identify the risk factors for in-hospital mortality. RESULTS A total of 412 patients were included in our study. Of these, 174 died after AKI-CRRT, and the remaining 238 were included in the survival control group. Multivariable logistic regression analysis revealed that EuroSCORE > 7 (odds ratio [OR], 3.72; 95% confidence interval [CI], 1.92-7.24; p < 0.01), intraoperative bleeding > 1 L (OR, 2.14; 95% CI, 1.19-3.86; p = 0.01) and mechanical ventilation time > 70 h (OR, 5.03; 95% CI, 2.40-10.54; p < 0.01) were independent risk factors for in-hospital mortality in patients who had undergone AKI-CRRT. Our study also found that the use of furosemide after surgery was a protective factor for such patients (odds ratio, 0.48; 95% confidence interval, 0.25-0.92; p = 0.03). CONCLUSIONS In summary, the mortality of patients with AKI-CRRT after cardiac surgery remains high. The EuroSCORE, intraoperative bleeding and mechanical ventilation time were independent risk factors for in-hospital mortality. Continuous application of furosemide may be associated with a better outcome.

Abstract
OBJECTIVE Severe acute kidney injury (AKI) and hyperbilirubinemia increase the morbidity and mortality risk in patients undergoing emergency surgery for acute type A aortic dissection (AAAD). Our purpose was to investigate the risk factors of mortality in AAAD surgery patients who had severe postoperative hyperbilirubinemia and AKI receiving continuous renal replacement therapy (CRRT). METHODS Patients who had severe hyperbilirubinemia and received CRRT after AAAD surgery in our center between January 2015 and December 2018 were retrospectively screened. Univariate and multivariate analyses were performed to identify the risk factors of in-hospital mortality. Kaplan-Meier curves were employed to evaluate the accumulated patient survival proportion. RESULTS After screening, 50 patients were included in our present study. The in-hospital mortality was 84%. The univariate logistic analysis showed that preoperative MAP (p = .017) and peak total bilirubin concentration (p < .001) were associated with in-hospital mortality in AAAD surgery patients who had severe postoperative hyperbilirubinemia and received CRRT. Multivariate logistic regression analysis revealed that the peak bilirubin concentration (odds ratio, 1.050; 95% confidence interval, 1.002-1.101; p = .041) after surgery was the only independent risk factor for in-hospital mortality. The optimal cutoff value of peak bilirubin for predicting in-hospital mortality was 134.4 μmol/L. CONCLUSIONS AAAD surgery patients with severe hyperbilirubinemia and AKI requiring CRRT had a poor prognosis. Increased postoperative peak bilirubin concentration strongly increased the risk of patient in-hospital mortality. Therefore, these patients should be closely monitored and treated aggressively when possible.

Abstract
Objective: Aortic endovascular stent implantation includes thoracic endovascular aortic repair (TEVAR), hybrid aortic repair (HAR), and ascending aorta stent implantation (AASI). In this study, we compared the surgical outcomes of stent-related type A dissection (SRTAD) compared with spontaneous type A dissection (STAD). Methods: From July 2011 to July 2014, we identified 17 SRTAD patients received surgical repair in our institution. Propensity score-matching was used to identify 34 STAD patients as controls. Results: Preoperative data of SRTAD group and STAD group had no statistical difference. Selective cerebral perfusion (SCP) time was longer in SRTAD group than in STAD group (P <0.05). SRTAD group had a longer cross-clamp time compared with STAD group (P <0.05). No intraoperative deaths in two groups. No differences in CPB time and concomitant procedures between two groups. In-hospital mortality was 11.76% (2 of 17) in SRTAD group and 2.9% (1 of 34) in STAD group (P <0.05). No differences were found in intensive care unit (ICU) time, ventilation, paraparesis, and other postoperative complications between SRTAD and STAD groups. No difference was found in survival rate between SRTAD and STAD groups in the postoperative 1-year follow-up. Conclusions: SRTAD patients received surgical repair had a higher in-hospital mortality compared with STAD, but no differences were found in postoperative complications and mid-term outcomes.

Abstract
OBJECTIVE To identify risk factors and long-term outcomes of acute kidney injury (AKI) in young patients who underwent type A acute aortic dissection (TA-AAD) emergency surgeries. METHODS This retrospective study enrolled 121 consecutive patients less than 40 years old who received TA-AAD emergency surgeries between January 2014 to December 2018 in Nanjing Drum Tower hospital. The diagnosis of AKI was made based on the KDIGO criteria. Multivariable regression analysis was performed to identify risk factors for postoperative AKI. Kaplan-Meier curves were generated to compare long-term outcomes between patients with and without AKI complication after TA-AAD surgeries. RESULTS Among all enrolled patients, AKI occurred in 51 patients (42.1%) and renal replacement therapy (RRT) was required in 15 patients (12.4%). The development of postoperative AKI was associated with increased 30-day mortality (P = 0.041), longer ICU stay time (P < 0.001) and hospital stay time (P = 0.006). Multivariable analysis indicated that elevated preoperative serum cystatin C (sCyC) (OR = 6.506, 95% CI: 1.852-22.855, P = 0.003) was the only independent risk factor for developing AKI. The areas under the receiver-operating characteristic curve (AUC) of preoperative sCyC was 0.800 (95% CI: 0.719, 0.882). Preoperative sCyC had a sensitivity of 64.7% and a specificity of 83.8% in diagnosing postoperative AKI with a cut-off value of 0.895 mg/L. In addition, our data suggested there was no difference discovered regarding long-term cumulative survival rate between patients with and without AKI during a median 29 months follow-up period. CONCLUSIONS Postoperative AKI after TA-AAD surgeries was relatively common in young patients and associated with increased short-term mortality. Elevated preoperative sCyC was identified as an independent risk factor for AKI with potential diagnostic merit.

Abstract
OBJECTIVES We seek to report our management protocol and early outcomes of acute type A aortic dissection (ATAAD) repair during the early phase of coronavirus disease 2019 (COVID-19). METHODS From January 23 to April 30, 2020, we performed ATAAD repair for 33 patients, including three with pregnancy-related TAADs. Confirmation of COVID-19 depended on the results of two nucleic acid tests and pulmonary computed tomography scan. Based on testing results and hemodynamic stability, patients were triaged to an isolated intensive care unit or negative pressure operating room for emergency surgery. RESULTS Mean age 50.2 ± 13.3 years and 20 were male (60.1%) and 8 patients were febrile (>37.3°C; 24.2%) and 17 were lymphopenic (51.5%). No patient was excluded from COVID-19 infection preoperatively. Extensive aortic repair with total arch replacement (TAR) was performed in 24 (72.7%), and limited proximal repair in 9 patients (27.3%). Cardiopulmonary bypass and cross-clamp times averaged 177 ± 34 and 88 ± 20 min for TAR, and 150 ± 30 and 83 ± 18 min for hemiarch, respectively. The mean operation time was 410 ± 68.3 min. Operative mortality was 6.1% (2/33). Complications included reintubation in four (12.1%), acute kidney failure in two (6.1%), and cerebral infarction in one (3.0%). No paraplegia nor re-exploration for bleeding occurred. COVID-19 was excluded in 100% eventually. No nosocomial infection occurred. Nor did any patient/surgical staff develop fever or test positive during the study period. CONCLUSIONS The results of this study show that our management protocol based on testing results and hemodynamic stability in patients with ATAAD during the COVID-19 pandemic was effective and achieved favorable early surgical outcomes.

Abstract
Background Organ dysfunction caused by hypothermic circulatory arrest continues to concern surgeons. The aortic balloon occlusion (ABO) technique can significantly shorten the circulatory arrest time in total arch replacement with frozen elephant trunk (TAR with FET). This study aims to analyze the renal protective effect of the ABO technique and to analyze the predictors of acute kidney injury (AKI) and continuous renal replacement therapy (CRRT) after TAR with FET. Methods Between August 2017 and September 2018, 247 patients who underwent TAR with FET were divided into ABO and moderate hypothermic circulatory arrest (MHCA) groups. The primary endpoint was postoperative AKI defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Multivariable logistic analysis was used to identify the predictors of AKI and CRRT after TAR with FET. Results With the application of the ABO technique, the circulatory arrest time was significantly shortened (ABO 4, IQR: 3-6 vs. MHCA 18, IQR: 16-20, P<0.001). Meanwhile, surgeons safely set the lowest nasopharyngeal temperature at a higher grade (ABO 28.1, IQR: 27.4-28.5 vs. MHCA 24.7, IQR: 24.1-25.1, P<0.001). The peak serum creatinine (SCr) values within 48 hours after the surgery was lower in the ABO group than in the MHCA group (ABO 124, IQR: 97-173 vs. MHCA 146, IQR: 108-221, P=0.008). The distribution of AKI grade according to the KDIGO criteria differed between the two groups (P=0.04): more patients in the ABO group were free from AKI (Grade 0) than patients in the MHCA group (33% vs. 23.1%), and the proportion of patients with high-grade AKI (Grades 2 and 3) in the ABO group was lower than that in the MHCA group (21% vs. 32%). The ABO technique was associated with reduced potential for AKI, but was not protective for CRRT. Conclusions The ABO technique significantly shortened the circulatory arrest time and safely elevated temperature, and provided better renal protection in patients undergoing TAR with FET. The ABO technique did not reverse the need for CRRT, nor did it reduce mortality or major adverse events.

Abstract
OBJECTIVE Acute kidney injury requiring renal replacement therapy after cardiac surgery has an incidence of 2% to 15%, and mortality in affected patients approximates 50%. The authors aimed to study the determinants of poor prognosis in patients receiving continuous renal replacement therapy (CRRT) after cardiac surgery. DESIGN Retrospective, observational single-center study. SETTING Tertiary care, university hospital. PARTICIPANTS Cardiac surgery patients admitted to the intensive care unit (ICU) needing postoperative CRRT between January 1, 2010, and September 31, 2019. INTERVENTIONS Predictors of mortality were examined using groupwide comparisons between ICU survivors versus nonsurvivors and univariate and multivariate Cox proportional hazards models. RESULTS During the study period, 67 cardiac surgery patients without prior maintenance dialysis required CRRT postoperatively. ICU mortality was 47.7% and 90-day mortality was 58.2%. Only 37.3% of patients were alive at 1 year after surgery. Blood lactate at the start of dialysis was the most significant predictor of ICU and overall mortality. Eighty-seven percent of patients with lactate >3 mmol/L died in the ICU compared with 27.3% of patients with lactate ≤3 mmol/L (p < 0.0001). In patients with lactate exceeding 5.3 mmol/L, ICU mortality was 100%. In a stepwise multivariate Cox proportional hazards model, the association with mortality remained significant for lactate at the start of CRRT (per 1 mmol/L, hazard ratio [HR] 1.19 [95% confidence interval {CI} 1.11-1.28], p < 0.0001), troponin T on the first postoperative morning (per 0.1 µg/L, HR 1.004 [95% CI 1.001-1.008], p = 0.01), and 72-hour fluid balance (per 1000 mL, HR 1.12 [95% CI 1.04-1.21], p = 0.005). CONCLUSION Blood lactate at the start of dialysis was the most significant predictor of ICU and overall mortality in patients with CRRT after cardiac surgery.

Abstract
Objective The study objective was to investigate the incidence and risk factors of continuous renal replacement therapy (CRRT) in patients undergoing emergency surgery for type A acute aortic dissection (TA-AAD) and evaluate the perioperative and long-term outcomes. Methods From January 2014 to December 2018, 712 consecutive patients were enrolled in the study. These patients were divided into two groups according to whether or not needed postoperative CRRT: the CRRT group vs the control group. Univariate analysis and binary logistic regression analysis were used to analyze the risk factors of CRRT. To avoid the selection bias and confounders, baseline characteristics were matched for propensity scores. Kaplan-Meier curves were generated to provide survival estimates at postoperative points in time. Results Before propensity score matching, univariate analysis showed that there were significant differences in age, preoperative hypertension, pericardial effusion, preoperative serum creatinine (sCr), intraoperative need for combined coronary artery bypass grafting (CABG) or mitral valve or tricuspid valve surgery, cardiopulmonary bypass (CPB) time, extracorporeal circulation assistant time, aortic cross-clamp time, drainage volume 24 h after surgery and ventilator time between two groups. All were higher in the CRRT group (P < 0.05). These risk factors were included in binary logistic regression. It showed that preoperative sCr and CPB time were independent risk factors for CRRT patients undergoing surgery for TA-AAD. And there were significant differences regarding 30-day mortality (P < 0.001) and long-term overall cumulative survival (P < 0.001) with up to a 6-year follow-up. After propensity scoring, 29 pairs (58 patients) were successfully matched. Among these patients, the analysis showed that CPB time was still significantly longer in the CRRT group (P = 0.004), and the 30-day mortality rate was also higher in this group (44.8% vs 10.3%; P = 0.003). Conclusion CRRT after TA-AAD is common and worsened short- and long- term mortality. The preoperative sCr and CPB time are independent risk factors for postoperative CRRT patients. Shorten the CPB time as much as possible is recommended to reduce the risk of CRRT after the operation.

Lower body ischaemic time is a risk factor for acute kidney injury after surgery for type A acute aortic dissection. Interact Cardiovasc Thorac Surg 2020; 30:107-112. [PMID: 31501854 DOI: 10.1093/icvts/ivz220] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Revised: 08/08/2019] [Accepted: 08/09/2019] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Postoperative acute kidney injury (AKI) is known as a risk factor for death after surgery for Stanford type A acute aortic dissection under hypothermic circulatory arrest. It may also adversely affect long-term survival. We searched for modifiable risk factors for postoperative AKI, focusing on lower body ischaemic time. METHODS We reviewed 191 patients undergoing surgical repair for Stanford type A acute aortic dissection. The distal anastomosis depended on excluding the primary tear location, resulting in ascending/hemiarch (n = 119), partial arch (n = 18) and total arch replacement (n = 54). We defined an increase in the serum creatinine level to ≧2 times the baseline level as AKI. The incidence of AKI was investigated with multivariate analysis of its risk factors. RESULTS Postoperative AKI was observed in 49 patients (26%), 31% of whom required renal replacement therapy. The overall hospital mortality rate was 8.5%. Postoperative AKI, preoperative shock and organ malperfusion were predictors of hospital death. Multivariate stepwise logistic regression analysis identified age, body mass index, preoperative chronic kidney disease and lower body ischaemic time as risk factors for postoperative AKI. CONCLUSIONS Although surgical repair for Stanford type A acute aortic dissection showed favourable results, the incidence of postoperative AKI is still high, closely associated with hospital death. Lower body ischaemic time should be recognized specifically as a modifiable surgical risk factor for postoperative AKI.

Effects of Autologous Platelet Rich Plasma on Intraoperative Transfusion and Short-Term Outcomes in Total Arch Replacement (Sun's Procedure): A Prospective, Randomized Trial. J Cardiothorac Vasc Anesth 2019; 33:2163-2169. [PMID: 31060939 DOI: 10.1053/j.jvca.2019.02.033] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2018] [Revised: 02/14/2019] [Accepted: 02/15/2019] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To observe the effect of collecting and retransfusing autologous platelet rich plasma (aPRP) on the amount of allogeneic blood usage in total arch replacement (Sun's surgery) and the outcomes 30 days after surgery. DESIGN A prospective, randomized trial. SETTING A tertiary university hospital specialized in cardiovascular diseases. PARTICIPANTS The study comprised 120 patients undergoing Sun's surgery for Stanford type A acute aortic dissection. INTERVENTIONS aPRP was harvested before incision and was re-transfused after heparin neutralization for patients in the treatment group. MEASUREMENTS AND MAIN RESULTS There was no significant difference in preoperative demographic data between the 2 study groups. Intraoperative transfusions of erythrocyte (p = 0.009), plasma (p = 0.017), cryoprecipitate (p = 0.002), and platelets (p < 0.001) in the treatment group were reduced significantly. In addition, less blood loss was observed in the treatment group (p = 0.002). The durations of postoperative mechanical ventilation (p = 0.029) and hospitalization (p = 0.002) of the treatment group were significantly shorter. There were no statistically significant differences in the length of intensive care unit stay, the incidence of complications, and mortality 30 days after surgery. CONCLUSION In total arch replacement (Sun's surgery), collecting and retransfusing aPRP reduced intraoperative transfusions of erythrocyte, plasma, and cryoprecipitate and decreased the duration of postoperative mechanical ventilation and hospitalization. This technique had no significant effect on the incidence of complications and mortality 30 days postoperatively.

Exp Ther Med 2018; 16:5025-5030. [PMID: 30546408 PMCID: PMC6256836 DOI: 10.3892/etm.2018.6873] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2018] [Accepted: 09/24/2018] [Indexed: 11/13/2022] Open
Abstract
Levels of D-dimer and interferon-γ (INF-γ) in pediatric patients with Mycoplasma pneumoniae pneumonia (MPP) were assessed to explore its clinical implication in evaluating the disease severity and patients' prognosis. Enrolled in this study as subjects were 185 pediatric patients with MPP who were admitted to the Department of Pediatrics of the Second Affiliated Hospital of Qiqihar Medical University and the First Hospital of Qiqihar City from January 2017 to October 2017 and 115 healthy children who underwent physical examination during the same time period. Patients were divided into two groups according to the severity of their pneumonia: Severe pneumonia group with 95 patients and mild pneumonia group with 90 patients. A total of 92 healthy children were assigned to the control group. Immunoassay was performed to measure the serum levels of D-dimer and INF-γ. The levels of these two markers were compared. In terms of D-dimer, the levels in pediatric patients in pneumonia groups were all higher than that in the healthy children (p<0.0001). After treatment for 120 h, the D-dimer and INF-γ levels in both pneumonia groups were lower than those before treatment (p<0.001). Among the patients in both the mild and severe pneumonia groups, those who developed extra-pulmonary complications had higher levels of D-dimer and INF-γ than those who did not developed extra-pulmonary complications (p<0.001). Increased levels of D-dimer and INF-γ were observed in pediatric patients with MPP. Assessment of the levels of D-dimer and INF-γ in serum may help with the diagnosis of severe MPP in children and predicting the occurrence of complications. This study provided more theoretical basis for the early diagnosis and identification of MPP in children, and can be used as a guideline in evaluating the severity and preventing complications.
