Angiography findings and endovascular management of acute nonvariceal gastrointestinal bleeding: A pictorial essay

Abstract

Patients with acute nonvariceal gastrointestinal bleeding (GIB) not treatable via endoscopic therapy require angiography and endovascular management. If the source of the bleeding can be identified on angiography, the bleeding can be controlled with minimal complications by endovascular treatments such as intra-arterial infusion of vasopressin, embolization, covered stent placement, or a combination thereof. This pictorial essay reviews the angiographic findings for and the endovascular management of acute nonvariceal GIB.
