An abdominal CT scan reveals multiple diverticula in the descending colon. He is admitted for observation overnight and 2 units of packed red blood cells are transfused. Around midnight, the patient has another episode of bleeding. At this time his heat rate is 120/min and his blood pressure is 88/54 mm Hg . A 99Tc-labeled red blood cell scan reveals active bleeding in the sigmoid colon and the bleeding source is subsequently determined by angiography. Given the patient's presentation, the best intervention option at this time is
A. colonoscopy and sclerosis of the bleeding site
B. intraarterial embolization
C. intraarterial vasopressin infusion
D. medical management and supportive care
E. partial colectomy and temporary colostomy
