Endovascular Treatment of Major Abdominal Arteriovenous Fistulas

Forty-eight articles were reviewed totaling a number of 54 patients including our own. The most common fistula site was the aortocaval segment. Aortic stent grafts were used in 78% of patients. Technical success was 94%. Intraoperative mortality was 0% with a 90-day mortality of 10%, half of which were not related to the primary pathology. Of the successful procedures, 12% of patients had major complications. One died before reintervention. All others had uneventful recoveries; 21% had minor complications treated conservatively. The majority of authors were in favor of this treatment modality.
