Short-term results of left subclavian artery reconstruction with branched thoracic endovascular aortic repair in the treatment of complex aortic arch lesions / 中华普通外科杂志

ABSTRACT

Objective To evaluate the short-term efficacy of branched TEVAR in the treatment of complex aortic arch lesions.Methods The clinical data of 18 patients with aortic lesions requiring reconstruction of the left subclavian artery who were treated with branch TEVAR technology in Tianjin Medical University General Hospital from Apr 2016 to Dec 2018 were analyzed retrospectively.Results There were 16 cases using Castor external branch stent implantation and 2 cases of self-made internal branch stent.The success rate of device release was 100％,the success rate of operation was 100％,and there were no intraoperative deaths.Postoperative complications occurred in 2 casesone proximal stent tear dissection required open surgery,one died of massive myocardial infarction.Seventeen patients were followed up for 1-8 months.CTA examination in 16 patients 30 days after surgery,found 1 patient with type Ⅲ endoleak.CTA examination done in 8 patients 6 months after surgery found distal occlusion of left subclavian artery stent in 1 patient necessitating distal stent implantation.Conclusion The branch TEVAR technique is effective method to reconstruct the arch branched artery.
