title: Embolization of a hemorrhoid following 18 hours of life-threatening bleeding.
abstract: Hemorrhoids usually do not pose diagnostic difficulties and they rarely cause massive bleeding. We report a case of massive rectal bleeding over 18 h needing 22 U blood transfusion treated by superselective transcatheter coil embolization 12 h following operative treatment performed in a different hospital. Diagnostic angiography with a view to superselective embolization, following failure of sigmoidoscopy to localize and treat the cause of hemorrhage, might act as a life-saving treatment in massive rectal bleeding, obviating the need for repeated endoscopy or emergency surgery.
