Renal artery-cholecystoduodenal fistula. A late complication of dacron patch angioplasty for renal artery stenosis.

A fistula formed between a false aneurysm of the renal artery, gallbladder, and duodenum after Dacron patch angioplasty for renal artery stenosis and led to massive gastrointestinal hemorrhage. The patient was successfully treated by renal artery ligation, nephrectomy, cholecystectomy, and closure of the duodenal fistula.
