DIAGNOSIS AND MANAGEMENT OF COLONIC ISCHEMIA AFTER ENDOVASCULAR GRAFT EXCLUSION FOR ABDOMINAL AORTIC ANEURYSM / 解放军医学杂志

ABSTRACT

Colonic ischemia is a well documented complication of abdominal aortic reconstruction. In this retrospective study of abdominal aortic aneurysm patients undergone endovascular graft exclusion, the incidence and management of this complication were investigated. From Mar 1997 to Apr 2000,among the 40 patients who received elective endovascular graft exclusion for,infrarenal abdominal aortic aneurysm the bilateral hypogastric artery was retained in 30 patients, the unilateral hyogastric artery was retained in 10 patients. One patient had lower abdominal pain on the 28th day after operation, CTA showed the bilateral hypogastric artery occlusion, the symptoms were relieved after drug treatment. Retaining unilateral hypogastric artery can prevent the colonic ischemia after endovascular graft exclusion for abdominal aortic aneurysm, the chronic colonic ischemia secondary to bilateral hypogastric artery occlusion can be relieved by effective drug treatment.
