Intraarterial vasopressin infusion of the inferior mesenteric artery was used in the treatment of 2 patients with massive hemorrhage following colonoscopic polypectomy. Both patients had multiple medical problems and were considered to be very-high-risk candidates for emergency surgery. Arteriography readily demonstrated the site of bleeding, and vasopressin infusion effectively controlled the hemorrhage in both patients without complication. Angiographic management allowed elective colonic resection 1 month later in 1 patient and prevented surgery in the other who has not bled again in the 6 months following the procedure. The role of arteriography in the management of postpolypectomy hemorrhage is discussed.
