Abstract
Intestinal volvulus may be the underlying process in patients presenting with intestinal ischemia. In 3 patients, angiographic findings of volvulus were erroneously interpreted as indicating occlusive or nonocclusive intestinal ischemia. In a 4th, the correct preoperative diagnosis was suggested by angiographic findings. Volvulus should be suspected at angiography by the whirlpool arrangement of the mesenteric arterial branches, the delayed filling and emptying of the arteries, and the intense opacification of the bowel wall. Familiarity with the angiographic picture of intestinal volvulus is essential for early diagnosis and for prompt initiation of appropriate therapy.
