BACKGROUND: The study aimed to compare the safety and effectiveness between fenestrated technique with or without chimney stent and single-branched stent graft for isolated left subclavian artery revascularization during endovascular repair of acute type B aortic dissection with unfavorable proximal landing zone.
METHODS: From January 2016 to December 2019, 65 acute type B aortic dissection patients with unfavorable proximal landing zone were treated with either the fenestrated technique (n = 34, group A) or single-branched stent graft (n = 31, group B). Type I endoleak, retrograde type A dissection, stroke, left subclavian artery patency, 30-day mortality, and aortic remodeling were systematically recorded and retrospectively analyzed.
RESULTS: Technical success rates for groups A and group B were 94.12% and 100%, respectively. Left subclavian artery primary patency was achieved for all enrolled patients. The incidence of type I endoleak, retrograde type A dissection, stroke, and 30-day mortality was 5.9%, 5.9%, 2.9%, and 2.9% in group A, respectively, but none were encountered in group B. Left subclavian artery occlusion was observed in 3 patients in group A and 2 patients in group B during a mean follow-up of 16.18 ± 2.08 months and 15.19 ± 2.68 months, respectively. After the procedure, significant aortic remodeling was detected in both groups during follow-up.
CONCLUSIONS: Both techniques are feasible and safe for isolated left subclavian artery revascularization during endovascular repair for acute type B aortic dissection. Apart from the associated perioperative risks of complications and mortality for the fenestrated technique, both procedures contributed to favorable aortic remodeling.
