Upper gastrointestinal hemorrhage associated with fistula formation in the duodenum due to a catheter placed in the hepatic artery

Various fistulous complications have been described in the gastrointestinal tract associated with the presence of a prosthesis or catheters located in the aorta or in other great abdominal arteries, either to resolve aneurysms or to bypass occlusive diseases. Exceptionally, enteric fistulas associated with a surgically implanted arterial chemotherapy infusion catheter in the hepatic artery may also occur, as has been previously demonstrated (2, 3).
