A Case of Aorto-duodenal Fistula Treated by Omental Plugging

Abstract

A 67-year-old man had a fever on the 5th day after abdominal aortic aneurysm replacement. An aorto-duodenal fistula (ADF) was suspected. After gastrointestinal angiography, CT showed the ADF.

At surgery, omental plugging was performed using esophagogastroduodenoscopy.

ADF is a complication of abdominal aortic aneurysms and has a high fatality rate. There is no established treatment for ADF. Many cases require revascularization and gastrointestinal resection.

Taking into account the patient's general condition, omental plugging may be recommended as one of the surgical techniques for ADF.
