Abstract
Between January 1976 and May 2005, the long-term results of 522 patients with aortoiliac lesions due to arteriosclerosis obliterans who underwent 319 aorto-femoral bypasses (group A), 88 femoro-femoral crossover bypasses (group B), 44 axillo-bilateral femoral bypasses (group C), and 71 endovascular procedures (group D) were examined. An endovascular procedure was selected for the short segmental stenotic lesions and a bypass for occluded lesions. If the patients were in generally good condition, an anatomical bypass was performed. If they were in poor general condition, an extranatomical bypass (femoro-femoral crossover bypass or axillo-femoral bypass) was performed. The primary patency rates were 91% and 86% at 5 and 10 years in group A, 73% and 73% in group B, 44% and 44% in group C, 83% at 5 years in group D. The survival rates were 83% and 62% at 5 and 10 years in group A, 59% and 30% in group B, 44% and 0% in group C, 79% at 5 years in group D. In conclusion, TASC II will be presented in 2007. The indications for endovascular procedure will be increase in the future, but we consider that the operative method which we chose as indicated by the prognosis and therapeutic results is appropriate at present.
