title: Gastrointestinal hemorrhage from fistula between traumatic pseudoaneurysm of the right hepatic artery and the duodenum.
abstract: The evaluation of gastrointestinal hemorrhage after abdominal trauma may be both urgent and difficult. After gunshot trauma, a fistula between the duodenum and a post-traumatic, hepatic artery pseudoaneurysm presented as a gastrointestinal hemorrhage. Tc-99m labeled RBC imaging demonstrated the pseudoaneurysm but did not show it as the source of the gastrointestinal hemorrhage--a large clot had formed, occluding the fistula. Angiography further delineated the lesion as arising from the right hepatic artery and transcatheter embolization was performed.
