Comparison of the efficacy and safety of super-selective and selective transcatheter arterial embolization in non-variceal gastrointestinal bleeding

For refractory NVUGIB, super-selective TAE compared to selective TAE reduces early rebleeding. Decision-making should prioritize patient transfusion needs, which was the sole independent predictor of rebleeding. The embolization strategy for LGIB should carefully consider the choice of embolic material and the inherent risk of intestinal ischemia.
