Angiography remains as the modality of choice in the diagnosis of lower gastrointestinal bleeding. Traditionally, angiography is used for localization of a bleeding source for surgical resection. Advances in transcatheter techniques have allowed for hemorrhage control through embolization of bleeding points, without the need for emergent laparotomy. ⋯ Angiography remains an important diagnostic tool in the management of lower gastrointestinal bleeding. In addition, it is a safe and effective treatment option, especially in patients with high surgical risk. Hemorrhage control obtained in the angiography suite may allow for patient stabilization and resuscitation with staging and bowel preparation for surgery. Patients need to be carefully monitored for evidence of bowel ischemia through the use of colonoscopy or computed tomography.
