Abstract Transcatheter arterial embolization (TAE) represents an effective treatment option for acute lower gastrointestinal bleeding (LGIB). This retrospective, bicentric study evaluated the safety and efficacy of TAE in 77 patients with LGIB. The mean patient age was 68.39 ± 17.54 years, pre-procedural hemoglobin 7.87 1.89 g/dL. most common cause LGIB angiodysplasia (36.2%). Pre-procedural computed tomography angiography (CTA) detected active 83% cases. Technical success achieved 98.7% patients, 30-day clinical 87%. rebleeding rate 13%, ischemic complication 11.7%. There were no significant associations between sex, age, coagulopathy, first-line management, signs, culprit vessel, superior mesenteric artery, or time CTA digital subtraction angiography. is a safe procedure LGIB, high technical acceptable rates. It should be considered standard select especially when endoscopic contraindicated not feasible.
