Successful revascularization of mesenteric infarction following aortography

Two cases of bowel infarction following abdominal aortography are presented. In both patients, two of the three major arteries supplying the bowel were occluded before the study. The superior mesenteric artery in one and the inferior mesenteric artery in the other were the only arteries supplying the bowel and their lumens were reduced. After the aortogram, the residual lumen clotted, leading to bowel necrosis. Survival was made possible in these two cases by revascularizing the superior mesenteric artery and resecting the necrotic bowel.
