Abstract
OBJECTIVE To compare the midterm outcomes of fenestration, branched stent-graft thoracic endovascular aortic repair, and hybrid procedures in treating aortic arch pathologies involving the left subclavian artery. METHODS We collected the clinical data from 144 patients with aortic arch pathologies involving and only involving the left subclavian artery (LSA) who underwent fenestration, branched stent-graft thoracic endovascular aortic repair, and hybrid procedures from November 2015 and December 2022 at a single center. Among the patients, 68 were treated by fenestration, 61 by branched stent-grafts, and 15 by hybrid surgery. The clinical data was retrospectively analyzed and compared. The primary outcome indicators included technical success and in-hospital mortality; others included the incidence of endoleaks, spinal cord ischemia, LSA patency, stent-related entry tear, aortic-related reintervention, operative time, blood loss, and aortic remodeling. RESULTS The technical success rate was 83.8%, 95.1%, and 100% (p = .046), and the in-hospital mortality rate was 1.5% (n = 1), 0%, and 0% (p = 1.000) in the fenestration, branched stent-graft, and hybrid surgery groups. Type I or III endoleaks occurred in 16.2% (n = 11), 4.9% (n = 3), and 0% of patients, respectively (p = .046). The operative time, blood loss, and hospitalization duration of the hybrid surgery group was significantly higher than those of the other two groups (p < .05). However, the surgery-related costs and total costs in the hybrid surgery group were lower than the other two groups (p < .001). The rate of LSA patency was 100% in the fenestration group and 98.3% in the branched stent-graft group (p = .475). The all-cause mortality rates were 10.9% (n = 7), 6.9% (n = 4), and 0%, respectively (p = .359). Spinal cord ischemia and other complications were not significantly different in each group, both in the perioperative and postoperative periods. In the subgroup analysis of patients with AD, the incidence of endoleaks was 28.9% (n = 13), 7.0% (n = 3), and 0%, respectively (p = .011), and stent-related new entry tears in each group were 2.2% (n = 1), 18.6% (n = 8), and 14.3% (n = 1), respectively, p = .032. The overall cumulative survival rate at 2 years was 90.0%, 92.4%, and 100%, respectively (p = .508). The true lumen area of the aortic arch and descending thoracic aorta in the stent segment was significantly larger postoperatively compared to that preoperatively in both of these three groups. CONCLUSION The fenestration technique is sophisticated with long learning curve and is prone to complications such as endoleaks with inexperience. Branched grafts are at greater risk of stent-related entry tears, which result in a higher rate of re-intervention. The hybrid technique broadens the indications for patients with aortic arch vessel variation and generally costs less, but the operative time is longer. Surgeons should select the optimal solution based on each patient's condition to achieve satisfactory results.

Abstract
CLINICAL IMPACT The GORE TAG Thoracic Branch Endoprosthesis (TBE) represents an interesting novelty in the management of thoracic aortic pathologies, particularly in urgent settings where left subclavian artery (LSA) coverage is required. By eliminating the need for additional LSA revascularization procedures, this device aims to reduce procedural complexity, operating time, and the risk of complications associated with traditional methods. Clinicians can achieve effective treatment with a single, off-the-shelf device, improving both patient outcomes and procedural efficiency. This case series highlights the potential of an off-the-shelf single-branched thoracic endograft in urgent settings.

[PMID: 40004819 PMCID: PMC11856155 DOI: 10.3390/jcm14041290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2024] [Revised: 02/04/2025] [Accepted: 02/10/2025] [Indexed: 02/27/2025] Open
Abstract
Background: Penetrating aortic ulcer (PAU) is an acute aortic syndrome characterized by a high rupture risk. There are several PAU-treatment procedures indicated for the management of this pathology associated with different effects on vessel morphology and hemodynamics. A deep evaluation of the different types of treatment may be helpful in decision making. Computational Fluid Dynamics (CFD) is a powerful tool for detailed inspection of cardiovascular diseases. The aim of this work was to implement a comparative analysis based on CFD evaluation of the effects of two type of PAU treatments. Methods: Thoracic endovascular aortic repair (TEVAR) with a left subclavian artery (LSA) branched aortic endograft (SBSG) and a hybrid approach including TEVAR and carotid-LSA bypass were considered. Aortic anatomical models were created from computed tomography (CT) images acquired before and after PAU treatment with SBSG for three patients. Starting from these models, a new aortic geometry corresponding to the outcome of the hybrid strategy was generated. Morphological analysis and CFD simulations were carried out for all aortic models to evaluate LSA outflow for the same predefined boundary conditions. Results: Reductions in LSA diameter were found between aortic models before and after the SBSG (18.2%, 20.8%, and 12.4% for CASE 1, CASE 2, and CASE 3, respectively). The flow rate at LSA changed between pre-configuration and aortic configuration after the PAU treatments: an averaged decrement of 1.08% and 7.5% was found for SBSG and the hybrid approach, respectively. The larger increase in pressure drop between the aortic arch and the LSA extremity was shown in the hybrid approach for all cases. Conclusions: CFD simulations suggest that SBSG preserves LSA perfusion more than a hybrid strategy and has less impact on thoracic aorta hemodynamics.

Abstract
BACKGROUND Published reports demonstrate that the use of Castor stent-graft is a promising treatment of aortic pathologies with the need to land in zone 2. However, there is a lack of publications on the medium-term results of Castor in the European population. This research evaluates the mid-term results of the Castor stent-graft in several Polish centers for the treatment of aortic pathologies and enriches the current knowledge of Castor stent-grafts. MATERIAL AND METHODS Twenty-one patients from 5 polish vascular surgery centers in subacute phase of type B aortic dissection (TBAD) with at least 1 classic risk factor of aneurysmatic degeneration, thoracic aortic aneurysms (TAAs) exceeding 5.5 cm, subacute phase of intramural hematomas (IMHs) and penetrating aortic ulcerations (PAUs) with at least 1 indication to endovascular treatment. Structure of the aortic arch and factors of aneurysmal degeneration for TBAD were highlighted. Early complications, long-term complications, and reinterventions after Castor device implantation are reported in the study. RESULTS Twenty (95.24%) patients survived, of which a technical success involving implantation of the Castor device in the correct location with a patent branch for the left subclavian artery, and no endoleaks were noted in 19 (90.48%) patients. After the procedure, there were 2 (9.52%) cases of type I endoleak (in which technical success was not achieved) and 2 (9.52%) cases of bird beak. In addition, 1 case of access site hematoma, 1 case of pseudoaneurysm, and 1 case of access iliac artery rupture requiring implantation of a Viabahn device were observed. During the follow-up period (mean 14 months; range = 1-40 months), 1 patient required reintervention due to type I endoleak and 1 patient due to left subclavian artery (LSA) branch thrombosis. Two patients required subsequent branched endovascular aortic repair procedure due to unfavorable remodeling and fast aneurysm formation in visceral aorta, regardless of Castor results. CONCLUSION The Castor device is an easy-to-use stent-graft with good medium-term results. It is an excellent option in cases requiring LSA revascularization during TEVAR. CLINICAL IMPACT In this study, we investigate the medium-term results of the Castor stent graft in patients with type B aortic dissection, thoracic aortic aneurysm, intramural hematoma and penetrating aortic ulceration. The medium-term results of treatment with the Castor device are not yet well studied. Currently, there are only a small number of publications on the safety, complications and success of Castor device implantation.

Abstract
BACKGROUND It is challenging to simultaneously conduct total endovascular repair and reconstruct the left subclavian artery (LSA) and isolated left vertebral artery (ILVA) in patients who had an ILVA and required zone 2 anchoring. This pilot study reported the initial application experience of thoracic endovascular aortic repair (TEVAR) with a proximal zone 2 landing for aortic arch reconstruction in patients with ILVA. METHODS This study was a retrospective consecutive single-center case series analysis, which involved four patients with ILVA who required zone 2 anchoring and received TEVAR combined with a single-branched stent graft and concomitant on-table fenestration between March 2021 and December 2022. RESULTS The postoperative follow-up period was 6-27 months, and no postoperative deaths or other primary complications occurred. There were no signs of a stroke or spinal cord ischemia, as well as no chest or back pain. The postoperative computed tomography angiography showed unobstructed ILVA and LSA, no stent stenosis and displacement, and no signs of endoleak. CONCLUSION The outcome suggested that this technique might be a feasible, safe, and alternative treatment for such patients. Further studies with larger samples and longer follow-up periods are needed to confirm our findings.

Abstract
Background The left subclavian artery (LSA) can be intentionally covered by a stent graft to acquire adequate landing zones for a proximal entry tear near the LSA during thoracic endovascular aortic repair (TEVAR). The Castor single-branched stent graft is designed to treat type B aortic dissection (TBAD) to retain the LSA during TEVAR. This study investigates clinical outcomes, aortic remodeling, and abdominal aortic perfusion patterns after TEVAR with the novel Castor device. Methods From November 2020 to June 2023, 29 patients with TBAD involving the LSA were treated with the Castor single-branched stent graft. In-hospital clinical outcome and aortic computed tomography angiography (CTA) data were analyzed. CTA was performed preoperatively and at follow-up to observe stent morphology; branch patency; endoleak; change in true lumen (TL), false lumen (FL), and transaortic diameters; and abdominal aortic branch perfusion pattern. Results The technical success rate was 96.6%. One failure was that the branch section did not completely enter the LSA and the main body migrated distally. No in-hospital mortality, paraplegia, or stroke occurred. During follow-up, one type Ib endoleak, four distal new entry tears, and one recurrent type A dissection arose from a new entry tear at the ascending aorta, no stent migration was observed, and the branch patency rate was 100%. At the thoracic aorta, TL diameters significantly increased, FL diameters markedly decreased, and FL was partially or completely thrombosed in most patients at follow-up. At the abdominal aorta, we observed 33.3% of TL growth and 66.7% of TL stabilization or shrinkage. The initial TL ratio at iliac bifurcation negatively predicted abdominal TL growth after TEVAR with a cutoff of 21.0%. Of the 102 abdominal aortic branches, 94.1% of the branches showed no change in perfusion pattern, 3.9% of the branches had an increased TL perfusion, and 2.0% of the branches had an increased FL contribution. Conclusion The Castor unibody single-branched stent graft offers an efficient endovascular treatment for TBAD involving the LSA. TEVAR with the Castor device effectively induced thoracic FL thrombosis and thoracic TL enlargement and resulted in abdominal TL growth when the initial TL ratio at iliac bifurcation is less than 21.0%. Abdominal aortic branch perfusion patterns remain relatively stable after TEVAR with the Castor stent graft.

Abstract
PURPOSE The aim of this study was to evaluate the midterm efficacy and safety of a single-branch Castor stent graft in the treatment of thoracic aortic disease. MATERIALS AND METHODS Clinical data of 106 patients with thoracic aortic disease treated with Castor single-branch stent graft at 3 centers were collected between May 2018 and June 2023. The indicators included technical success, stent-related complication, reintervention, retrograde dissection, endoleak, distal stent graft-induced entry (dSINE), branch patency, and mortality. The outcomes of the Castor stent graft for multibranch reconstruction above the arch was also analyzed. RESULTS The technical success was 98.1% (104/106), while the surgical success was 93.4% (99/106). The reintervention was 2.8% (3/106), consisting of a case of retrograde type A dissection, an endoleak, and a dSINE. The retrograde dissection was 1.9% (2/106), while type I endoleak was 1.9% (2/106). The new dSINE was 2.8% (3/106), and the branch patency rate was 100%. The mortality was 1.9% (2/106). The mean follow-up time was 29.1±17.7 months. The 2-year post-surgery cumulative survival rate was 91.0%±3.1%, while the cumulative branch patency rate was 96.2%±2.2%. In addition, the cumulative freedom from stent-related reintervention rate was 93.2%±2.8%. A comparison showed no significant difference in the stent-related complication, branch patency, endoleak, reintervention, and mortality when the proximal end of the Castor stent graft was anchored to zones 1 or 2 of the aorta. CONCLUSION Castor single-branch stent graft showed favorable early and midterm outcomes in the treatment of thoracic aortic disease. In addition, it was feasible to combine Castor stent graft with other advanced techniques for multibranch aortic arch reconstruction. CLINICAL IMPACT The Castor single-branch stent graft was approval by the Chinese Food and Drug Administration in 2017. However, there were few studies on the mid-term outcomes for thoracic aortic disease after launching, which mainly focused on small single-center retrospective study. In the study, we assessed the mid-term outcomes of Castor stent graft through multi-center cases, Castor stent graft combined with other advanced techniques (such as fenestration and hybrid) for multi-branch reconstruction of aortic arch were also conducted. We found Castor single-branch stent graft showed favorable early and mid-term outcomes in the treatment of thoracic aortic disease. Additionally, it was feasible to combine Castor stent graft with other advanced technique for multi-branch aortic arch reconstruction. As an off-the-shelf branched stent graft with a wide range of models, it could be also used in most emergent situation. The Castor stent graft was expected to become more widely used in the future.

Abstract
BACKGROUND This study aimed to evaluate the safety and efficacy of physician-modified endovascular graft for preservation of left subclavian artery during thoracic endovascular aortic repair. METHODS From June 2019 to October 2022, 66 patients with a variety of thoracic aortic pathologies were treated with thoracic endovascular aortic repair using physician-modified endovascular graft left subclavian artery fenestration to achieve adequate proximal landing zone. The details of surgical techniques were described. The perioperative morbidity, mortality, and the outcomes of mid-term follow-up were analyzed. RESULTS Of the 66 patients (men: women, 53:13; age, 55.18 [55.18 ± 10.62] years), 53 (80.30%) presented with type B aortic dissection, 10 (15.15%) with thoracic penetrating aortic ulcer, 2 (3.03%) with thoracic aortic aneurysm, and 1 (1.52%) with left subclavian artery aneurysm. All of them underwent thoracic endovascular aortic repair using physician-modified endovascular graft left subclavian artery fenestration on the sterile back table. The technique success rate was 96.97% (n = 64). Total operation time was 92 min (interquartile range, 86-118), graft modification time was 19 min (interquartile range, 17-21), fluoroscopy time was 49 min (interquartile range, 41-62), and contrast agent dosage was 165 mL (interquartile range, 155-185). 30-day perioperative morbidities were 3 (4.55%) strokes, 1 (1.52%) retrograde type A aortic dissection, 1 (1.52%) aortic intimal intussusception, 1 (1.52%) left arm ischemia, and 3 (4.55%) type Ia endoleaks. Postoperative 30-day mortality and reintervention rates were 1.52% and 4.55%, respectively. Among the 63 patients included in the follow-up of 17 months (interquartile range, 7.75-18.25), the primary patency of left subclavian artery fenestration stents was 100%. Late complications were 1 (1.59%) distal stent graft-induced new entry and 1 (1.59%) death due to retrograde type A aortic dissection during the follow-up. The stent graft-induced new entry patient was observed with stable false lumen. CONCLUSIONS Thoracic endovascular aortic repair with physician-modified endovascular graft for left subclavian artery revascularization is a safe, feasible, and efficacious technique associated with high success rate. Further study is needed for long-term outcome investigation.

Trimarchi G, Benedetti G, Palmieri C, Rizza A. A Case of Type B Aortic Dissection: The Role of Transesophageal Ultrasound Guidance in Thoracic Endovascular Aortic Repair. J Cardiovasc Echogr 2023; 33:148-152. [PMID: 38161772 PMCID: PMC10756321 DOI: 10.4103/jcecho.jcecho_64_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 10/28/2023] [Accepted: 10/29/2023] [Indexed: 01/03/2024] Open
Abstract
Thoracic endovascular aortic repair (TEVAR) plays a central role in managing acute and chronic aortic pathologies. With the advancement of transcatheter structural heart procedures, echocardiography has become a key in procedural guidance. Despite consensus on its use for cardiac interventions, ultrasound assistance in aortic procedures is not widely standardized. A 71-year-old obese man with chronic type B aortic dissection underwent a TEVAR procedure, using a single-branched aortic stent graft (Endovastec™ Castor™) and with transesophageal ultrasound guidance. The preprocedural assessment confirmed the presence of aortic dissection of the descending thoracic aorta with a posterior true lumen (TL) and an anterior false lumen (FL), normal aortic valve anatomy and function, normal left ventricular function, absence of intracavity thrombus, and absence of aortic plaques that could prevent the optimal implantation of the stent graft. During the procedure, a transesophageal echocardiogram (TEE) monitored the positioning of the guide wires, the arrival of the catheter of the thoracic endoprosthesis, and then the implantation of this at the level of the aortic arch and the descending thoracic aorta. Postprocedure TEE evaluation underlined full stent-graft deployment without leaks and successful exclusion of FL with the beginning of thrombosis. Angiography confirms the exclusion of the aneurysm and the absence of endoleaks. This clinical case demonstrates how transesophageal echocardiographic guidance can improve the TEVAR procedure by minimizing fluoroscopy time, contrast medium use, and enabling a better assessment of the dissection anatomy with real-time monitoring of both the TL and the FL. In conclusion, TEE can serve as an auxiliary intraoperative imaging tool to provide good information before, during, and after the procedure, increasing the success and safety of the TEVAR.

Single branched endografts for the preservation of left subclavian artery in the treatment of zone II thoracic aortic lesions a systematic review and meta-analysis. Ann Vasc Surg 2023:S0890-5096(23)00240-6. [PMID: 37121340 DOI: 10.1016/j.avsg.2023.04.019] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 04/15/2023] [Accepted: 04/21/2023] [Indexed: 05/02/2023]
Abstract
BACKGROUND We investigated the safety and feasibility of single branched endografts in the treatment of zone II thoracic endovascular aortic repair (TEVAR). METHODS We performed a systematic research on Medline, Scopus and EMBASE for articles published up to February 2023. Primary endpoints included technical success, thirty-day mortality, stroke and spinal cord injury (SCI) as well as unassisted left subclavian artery (LSA) branch patency by the end of follow-up. Secondary endpoints included early thirty-day and persistent endoleaks, new onset dissection and reintervention by the end of follow-up. RESULTS Fourteen studies, three prospective case series and eleven retrospective case series comprised of 727 patients were finally included. The pooled technical success and thirty-day mortality rates were 94.86 % (95% CI: 90.95-97.86) and 0.14% (95% CI: 0.00-0.87). The thirty-day stroke and SCI rates were 0.45% (95% CI: 0.00-1.39) and 0.08% (95% CI: 0.00-0.99) respectively, while the unassisted LSA branch patency estimate was 99.12% (95% CI: 97.97-99.86). The early thirty-day and persistent endoleak rates were 5.19% (95% CI: 2.45-8.65) and 2.57% (95% CI: 0.36-6.02), whereas new onset dissections and reinterventions estimates were 0.94% (95% CI: 0.17-2.11) and 2.40% (95% CI: 0.41-5.42). CONCLUSION While we have displayed the safety and feasibility of single branched endografts in the treatment of zone II thoracic aortic lesions, physicians should be aware of the persistency displayed by early type I endoleaks eventually requiring re-intervention. The variations in device and lesion characteristics accompanied by the short-term follow-up presented in our review do not allow for definite conclusions to be drawn, necessitating further research through high-quality randomized controlled trials.
