Ischemic colitis (IC), a common cause of lower gastrointestinal bleeding, is typically managed with conservative treatment. However, when hematochezia persists despite endoscopic hemostasis, radiologic intervention becomes a viable therapeutic alternative. This report aims to present three cases of IC associated with massive bleeding successfully treated using radiologic therapies. One patient with IC secondary to occlusive disease, characterized by significant stenosis at the superior mesenteric artery orifice, underwent stent placement, while the other two patients with non-occlusive IC were treated with embolization using microcatheters and Gelfoam. All cases resulted in technical and clinical success, with no procedure-related complications. This case series highlights the potential role of radiologic intervention as an effective, minimally invasive treatment option for select patients with IC who present with persistent hematochezia despite conservative or endoscopic management.
