PURPOSE
To assess the clinical benefits and complications of thoracic endovascular aneurysm repair (TEVAR) using a single-branched stent-graft in patients with thoracic aortic diseases (TADs) involving the left subclavian artery (LSA).
METHODS
This retrospective study reviewed patients with TADs involving the LSA treated with TEVAR using a unibody single-branched stent-graft (Castor single-branched stent-graft, Shanghai MicroPort Endovascular (Group) MedTech Co., Ltd.) from November 2017 to May 2021. Clinical follow-ups and computed tomographic angiography (CTA) were conducted at 1 week, 3 months, 6 months, and annually.
RESULTS
A total of 114 patients underwent TEVAR with Castor stent-graft. Among 114 patients, 88 had TBAD, 14 had PAU, 6 had pseudoaneurysms, 3 had TAA, and 2 had IMH. Technical success (defined as successful deployment and patency of all stent segments) was 100%. No mortality, endoleak, stroke, or paraplegia was observed during a mean follow-up of 19.8 months. One case of LSA occlusion (0.9%) was noted at 3-month follow-up, without neurological symptoms.
CONCLUSION
The Castor single-branched stent-graft is effective for treating TADs involving the LSA, with high technical success and no short- or midterm complications. Further research is needed to confirm long-term safety and efficacy.
目的
评估使用单分支覆膜支架对累及左锁骨下动脉（LSA）的胸主动脉疾病（TADs）患者进行胸主动脉腔内修复术（TEVAR）的临床益处和并发症。
方法
这项回顾性研究纳入了2017年11月至2021年5月期间使用一体式单分支覆膜支架（Castor单分支覆膜支架，上海微创心脉医疗科技（集团）股份有限公司）接受TEVAR治疗的累及LSA的TADs患者。在术后1周、3个月、6个月及每年进行临床随访和计算机断层血管造影（CTA）检查。
结果
共有114例患者接受了Castor支架型人工血管TEVAR治疗。114例患者中，88例患有胸主动脉夹层（TBAD），14例患有穿透性主动脉溃疡（PAU），6例患有假性动脉瘤，3例患有胸主动脉瘤（TAA），2例患有主动脉壁内血肿（IMH）。技术成功率（定义为所有支架段成功植入且通畅）为100%。在平均19.8个月的随访期内，未观察到死亡、内漏、中风或截瘫病例。3个月随访时发现1例LSA闭塞（0.9%），无神经症状。
结论
Castor单分支覆膜支架治疗累及LSA的TADs有效，技术成功率高，无短期或中期并发症。需要进一步研究以证实其长期安全性和有效性。
