Long segmental embolization was done with N-butyl cyanocrylate (NBCA) to prevent back flow from the superior mesenteric artery. Spot radiograph (B) and superior mesenteric artery angiogram (C) show NBCA cast (arrowheads) without further bleeding. D. A computed tomography scan 4 days later showed bowel ischemia and perforation (arrows) with peritonitis surrounding radiopaque embolic material (arrowheads).
