Endovascular abdominal aortic aneurysm repair in patients with challenging anatomy: utility of the hybrid endograft

Abstract

Commercially available aortic stent grafts differ in construction and clinical advantage such that creating hybrid endografts by combining components from different manufacturers is sometimes useful. We describe a multicenter experience using hybrid endografts to treat patients with challenging anatomy. Hospital records and office charts were reviewed from four institutions. Hybrid endografts were defined as those with two types of covered stents in continuity to treat an abdominal aortic aneurysm (AAA). Indications for hybrid grafts were defined by type of endoleak and whether an endoleak was expected or unexpected as determined by the preoperative radiographic evaluation. Endpoints include intraoperative endoleaks, late endoleaks, change in aneurysm size, and rupture. Hybrid endografts were used to treat AAA (endovascular aneurysm repair [EVAR]) in 90 patients, representing 7.9% of the total multicenter experience. In 7 patients (7.8%), a hybrid graft construction as a secondary procedure successfully corrected a type 1 endoleak. In the remaining 83 patients (92.2%), hybrid grafts were created at the time of original EVAR to treat expected challenging anatomy or unexpected endoleaks. Hybrid endografts corrected 88 (97.8%) typ...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.
