Clinical Analysis of Aortoiliac Occlusive Disease

ABSTRACT

PURPOSE: Aortoiliac occlusve diseases are common disease of chronic artherosclerosis in patients in lower extremities. We compared the operative results of anatomic reconstruction with those of an extraanatomic bypass to evaluate the true benefit of one over other procedure. METHOD: 115 patients who underwent surgery from January 1995 to May 2001 were retorspectively reviewed. The patients were classified in two group: a direct anatomic reconstruction group and an extraanatomic bypass group. Operative risk were analyzed by the scoring system recommended by the Subcommittee on Reporting Standards for Lower Extremity Ischemia of International Society for Cardiovascular Surgery(ISCVS). Risk factor, graft patency were analyzed between two group. RESULT: Graft patiency was better in anatomic reconstruction but it was not statistically significant. The important risk factors in deciding the extraanatomic bypass were age and degree of the organ injury, especially heart disease. CONCLUSION: Preoperative evaluation of the risk factors was important in decision making but statistically not significant. Patency of the deep femoral artery was sufficient for runoff and extensive profundaplasty prevented the femorodistal bypass.
