Transcatheter embolization for treatment of diverticular hemorrhage.

Two patients underwent transcatheter embolization for control of massive diverticular hemorrhage after vasopressin infusion had failed to control the bleeding. The role of angiography in the management of diverticular bleeding is discussed. If surgery is being considered, angiography should be utilized to localize the bleeding site and to permit limited colonic resection. Transcatheter embolization is proposed as an alternative to operative intervention.
