Abstract
Interventional radiology (IR) can play a key role in the management of gastrointestinal (GI) bleeding, especially when endoscopy fails or if the patient is a poor surgical candidate. IR can locate as well as treat the bleeding site. In most algorithms, endovascular therapy by IR is used after endoscopy, but it can be considered a first-line intervention when visualization is likely to be poor, as with an unprepped colon with high suspicion of a lower GI bleed, or if the patient is unstable and endoscopic yield is felt to be low, such as in a briskly bleeding patient. In the case of upper GI bleeds, a distinction should be made between variceal and non-variceal bleeding sources as arterial interventions on the former would not be applicable. Proper utilization of IR requires a multidisciplinary approach and good communication among providers such that the bleeding patient gets the most appropriate therapy with the most efficient use of time.
