Endovascular repair of abdominal aortic aneurysms with aortocaval fistula

Abstract

Objectives: To examine the risk of high-flow type II endoleak following endovascular repair of abdominal aortic aneurysm with aortocaval fistula.

Design: Case reports.

Subjects: Two patients with abdominal aortic aneurysms with aortocaval fistula.

Methods: Both patients had an endovascular repair of their aortic aneurysms.

Results: The aneurysms were successfully treated in both patients, without any endoleak on completion angiography. Apart from a transient type II lumbar endoleak in one of the patients, no endoleak was found after 3 and 12 month follow-up. Seven other cases have been published, reporting one type II and one type Ic endoleak.

Conclusion: We found no evidence that endovascular repair of abdominal aortic aneurysm with aortocaval fistula is associated with a higher incidence of persistent endoleak.
