Aortic Aneurysmal Repair With Surtureless Visceral Revascularization Using Novel Hybrid Vascular Graft and a Gradual Funneling Technique

Abstract

This article details a novel technique in the treatment of a symptomatic thoracoabdominal aneurysm (TAA) involving the visceral segment and an infrarenal abdominal aortic aneurysm. The patient was treated in a 2-staged hybrid approach combining an endovascular repair of the infrarenal segment, followed by open TAA repair. The large visceral arteries were revascularized using expanded polytetrafluoroethylene GORE Hybrid Vascular Graft (GHVG) and a Gradual Funneling Technique with Dacron graft. This method assured a complete hemostatic seal and minimized visceral ischemic time. To our knowledge, this is the first case of sutureless visceral artery revascularization using GHVG reported in the literature.
