Primary aortoduodenal fistula presenting as a rare cause of upper gastrointestinal bleeding

Abstract

Primary aortoduodenal fistula (ADF) is a serious life-threatening condition.Unlike secondary ADF which occurs in patients who had previous aortic prosthetic reconstruction, primary ADF is uncommon. Its diagnosis is often unsuspected until surgery or postmortem. We report a rare case of primary ADF presenting as massive gastrointestinal bleeding.

Primary aortoduodenal fistula: As a first presentation of brucellosis; a case report

“…Its prevalence is estimated to range from 0.04 % to 0.07 % [ 5 ].According to published research, PAEFshave an 80–100 % total fatality rate without surgical intervention. Although the exact cause of PAEF formation remains unknown, atherosclerotic AAA is identified in 83 % of cases, suggesting that repetitive mechanical stress induced by the pulsation of the aneurysm may be a hallmark of PAEF development [ 5 , 10 ].…”
