摘要

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