Abstract

To assess safety and feasibility of in situ laser stent graft fenestration to revascularize the left subclavian artery (LSA) during thoracic endovascular repair (TEVAR) of type B aortic dissection (TBAD) with limited proximal landing zones with 5 years of follow-up. In a single-center retrospective study, 130 patients with TBAD with limited proximal landing zones (≤ 1.5 cm) underwent in situ laser stent graft fenestration revascularizing the LSA during TEVAR from April 2014 to April 2019. Outcomes were assessed by CT angiography and clinic visits, including technical success rate, operative time, LSA patency, ischemic events, and late aorta-related complications during follow-up. Mean age of patients was 53 y (range, 33-73 y). Primary technical success rate was 96.9% (126/130). Three chimney stents were placed instead of fenestration, and 1 LSA fenestration was combined with a left common carotid artery (LCCA) chimney stent. Mean operative time was 53 min ± 28 with fluoroscopy time of 40 min ± 15. There were no neurologic complications and no deaths, with a mean duration of hospital stay of 9 d (range, 5-21 d). At a mean follow-up of 42 mo (range, 5-60 mo), there was a 97% primary LSA patency. Four patients had a type I endolea...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
