Secondary aortoenteric fistula is a potentially lethal complication after aortic surgery. Traditional treatment consists of open graft excision with extra-anatomic bypass or in situ reconstruction. Patients who present in extremis, however, are generally poor candidates for re-do open aortic surgery. Endovascular repair has emerged as an alternative treatment modality for patients who would otherwise be unable to tolerate an extended operation. We report here a case of urgent endovascular repair of a juxtarenal secondary aortoenteric fistula via endovascular aneurysm repair with a renal artery chimney in a patient with a solitary kidney who presented in hemorrhagic and septic shock.
