Core tip: Acute gastrointestinal bleeding can lead to significant morbidity and mortality without appropriate treatment. The role of interventional radiology is crucial in patients that have persistent bleeding despite medical and endoscopic treatment. Computed tomography angiography and nuclear scintigraphy can localize lesions and provide information helpful for the Interventional Radiologist. The source of bleeding can be then be stabilized with endovascular angiography/transcatheter arterial embolization which is safe and effective with minimal complications due to the advances in catheter technology.
