A Novel Technique for Sutureless Proximal Aortic Endograft Revision in Type 1A Endoleak.

Abstract

Management of type 1A endoleaks can be challenging. In the endovascular era, this condition is expected to become more frequent. Conventionally, surgical explant of the endograft remains the "last-resort" surgical treatment when all endovascular or other open options are exhausted. Endograft removal is a difficult and morbid procedure. An alternative technique is described that involves cinching the endograft after disengagement of the proximal fixation hooks. The endograft is redeployed within a prosthetic aortic replacement graft with an overlapping zone. This can reduce complications such as from additional anastomoses, graft bleeding, prolonged clamping, operative time, and associated comorbidities.
