Purpose: To demonstrate results in managing lower gastrointestinal (GI) bleeding with the use of superselective catheterization and intentional induction of vasospasm of the bleeding vessel without the use of embolic agents or vasospasm-inducing medications.
Materials And Methods: A retrospective review of 15 episodes of lower GI bleeding treated in the past 6 years by intentional catheter-induced vasospasm (CIV) to achieve thrombosis of a bleeding source was conducted. Nine patients had angiographically proven inferior mesenteric artery bleeding and six had angiographically proven superior mesenteric artery bleeding.
