Successful management of abdominal aortocutaneous fistula following emergency endovascular aneurysm repair for aortoenteric fistula in a patient with Takayasu arteritis

Abstract

Aortocutaneous fistula is an extremely rare complication after aortic endograft infection. We report on the management of a patient who presented with aortocutaneous fistula following emergency endovascular aneurysm repair (EVAR) of an aortoenteric fistula (AEF). A 50-year-old female with Takayasu arteritis who had undergone thoracic endovascular aortic repair (TEVAR) for a thoracic aortic aneurysm, 23 years ago presented with a spontaneous abdominal AEF and another contained ruptured descending thoracic aortic aneurysm distal to the previous endograft. She underwent emergency bridge EVAR and redo-TEVAR. Thirteen months following EVAR, she presented with endograft infection and a spontaneous aortocutaneous fistula. She was successfully managed with an axillo-unifemoral bypass followed by EVAR endograft explantation. She was discharged on long-term antibiotics and has been symptom free for 12 months.
