Clinical analysis of colon ischemia complicating with operated abdominal aortic aneurysm / 中华外科杂志

ABSTRACT

OBJECTIVE To investigate the etiology, prevention and treatment of colon ischemia after operation for abdominal aortic aneurysm (AAA). METHOD Seven of 140 cases complicated with colon ischemia who had received AAA operation were analyzed retrospectively. RESULTS Three cases underwent emergency operation. The seven cases were subjected to removal of AAA, implantation of prosthesis, and ligation of the inferior mesenteric artery. Two cases had the ligation of the bilateral internal iliac artery (IIA). Epilateral IIA was ligated in 2 cases. Bowel resection was carried out in 3 cases, 1 of which received reconstruction of the inferior mesenteric artery (IMA). Three cases received conservative therapy, but died from multiply organ failure. CONCLUSION Correct prevention and management of colon ischemia can effectively reduce the operative morbidity of AAA patients.
