  		Fig. 4C. —Microcoil embolization in 84-year-old woman with rectal barium impaction performed after failed colonoscopy. Repeated superselective arteriogram after embolization shows no further hemorrhage. Note right orthotopic ureterocele. Patient's condition stabilized after embolization, but less severe bleeding recurred 12 hr later and patient underwent successful endoscopic treatment.

  		Fig. 5B. —Bowel infarction after embolization in 68-year-old woman. Repeated digital subtraction inferior mesenteric arteriogram after embolization shows no extravasation. Microcatheter could not be advanced to source of bleeding; therefore, microcoils were deployed in marginal artery approximately 5 cm below bleeding site.

  		Fig. 5D. —Bowel infarction after embolization in 68-year-old woman. Digital subtraction superior mesenteric arteriogram obtained after additional marginal artery embolization shows no further extravasation. Approximately 1 week after embolization, left hemicolectomy was performed for continued pain and pathologic analysis revealed bowel infarction.
