title: Abrupt occlusion of right gastroepiploic artery as an angiographic evidence of gastrointestinal hemorrhage.
abstract: Angiography plays an important role in both diagnosis and treatment of gastrointestinal (GI) bleeding; however, the sensitivity is low for diagnosis. We report a case of a 38-year-old woman who presented with recurrent upper GI bleeding following central pancreatectomy. Multiple selective arteriograms failed to reveal any active bleeding or other common signs of bleeding. There was an abrupt occlusion of the right gastroepiploic artery initially interpreted to be a surgical ligation. Upon direct superselective injection near the occlusion, an area of frank contrast extravasation was demonstrated immediately beyond the occlusion. The underlying vessel was embolized with n-butyl cyanoacrylate without recurrent bleeding up to 3-month follow-up.
