Feasibility and outcome of partial open surgical fenestrated stent graft explantation, radical debridement, and in situ reconstruction for late graft infection

Abstract

Aortic stent graft infection is a rare, but potentially lethal, complication of endovascular aortic aneurysm repair. Definitive treatment is complete stent graft explanation with in-line or extra-anatomical reconstruction. However, several factors can render such an operation unsafe, including the patient's overall fitness for surgery and partial incorporation of graft with a resulting robust inflammatory process, especially around the visceral vessels. We present the case of a 74-year-old man with a history of an infected fenestrated stent graft that was managed with partial explantation, wide debridement, and in situ reconstruction using a rifampin-soaked graft and a 360° omental wrap with good results.
