Endovascular Management of Aortic Stump Blowout by Parallel Grafting and Coil Embolization of Visceral Aorta

Abstract

Aortic graft and endograft infections remain a significant source of morbidity and mortality after abdominal aortic aneurysm repair. With graft excision and extra-anatomic bypass, an infrarenal aortic stump remains which can have suture line dehiscence and catastrophic stump blowout. Treatment of this is extremely challenging, especially for severely co-morbid patients who cannot undergo major surgery, or in patients with a hostile abdomen. We present a case study of a 74-year-old male found to have an aortoenteric fistula (AEF). This case broadens operative options for this type of patient population by demonstrating an endovascular technique for addressing aortic stump blowout by parallel grafting and coil embolization of the visceral aorta.
