Left Subclavian Artery Revascularization With In Situ Laser Fenestration During Thoracic Endovascular Aortic Repair for Acute Complicated or High-Risk Type B Aortic Dissection: Results of the LLTEVAR Trial.

ABSTRACT:

Background

Coverage of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) increases the risk of major adverse events (MAEs). In situ laser-assisted fenestration allows for LSA revascularization in both elective and urgent settings, yet its safety and efficacy lack robust multicenter data.

Methods

LLTEVAR (LSA Revascularization With Laser-Assisted Fenestration During TEVAR) was a prospective, single-arm, multicenter study that enrolled patients with acute complicated or high-risk acute TBAD. The primary safety end point was freedom from composite MAEs (mortality, stroke, myocardial infarction, paraplegia, type Ia endoleak, and retrograde aortic dissection/intramural hematoma) within 30 days after the procedu
