title: Endovascular therapy of spontaneous aortocaval fistulae associated with abdominal aortic aneurysms.
abstract: We report a case of an abdominal aortic aneurysm (AAA) associated with an aortocaval fistula managed with endovascular techniques. The patient had a known AAA, and on the latest computed follow-up tomographic scan, evidence of fistulization between the aorta and the vena cava was suggested, which was later corroborated by standard contrast angiography. His comorbidities precluded an open repair, and this prompted consideration for an endovascular intervention. Successful exclusion of the AAA was performed, with no evidence of endoleaks or persistence of the fistula. The endovascular approach provides an efficacious alternative to traditional methods for repair of an aortocaval fistula, which is especially important in elderly patients with several comorbidities.
