PURPOSE: To evaulate the efficacy and safety of emergent superselective transcatheter embolization forcontrolling massive colonic bleeding. MATERIALS AND METHODS: Six of the seven patients who had symptom of massive gastrointestinal bleeding underwent emergent transcatheter embolization for control of the bleeding. Gastrointestinal bleeding in these patients was originated from various colonic diseases ; rectal cancer(n=1), proctitis(n=1), benign ulcer(n=1), mucosal injury by ventriculoperitoneal shunt(n=1), and unknown(n=2). All patients except one with rectal cancer were critically ill. Superselective embolization were done by using Gelfoamparticles and/or coils. RESULTS: The vessels embolized were ileocolic artery(n=2), superior rectal artery(n=2), inferior rectal artery(n=1), and middle and inferior rectal arteries(n=1). Hemostasis was successful immediatelyin all patients. Two underwent surgery due to recurrent bleeding developed 3 days after the procedure(n=1) or in associalion with underlying rectal cancer(n=1). On surgical specimen of two cases, there was no mucosal ischemic change. CONCLUSION: Transcatheter embolization is a safe and effective treatment of method for the control of massive colonic bleeding.
