Rare but critical: Aberrant vascular communication leading to multiorgan ischemia after prophylactic gastroduodenal artery embolization for refractory upper gastrointestinal bleeding.

Upper gastrointestinal bleeding (UGIB) carries a high risk of morbidity and mortality despite recent improvements in diagnosis and management. Many patients failed to respond to initial endoscopic and medical management. Transcatheter arterial embolization (TAE) is now considered the next line of therapy over surgery in refractory UGIB because of its good safety profile and high technical and clinical success rate.
