Abstract:
From November 1976 to December 1991, we performed extra anatomic bypass procedures (EAB) in 100 cases with aortoiliac occlusive disease. The operative procedures included 26 axillo-femoral bypasses (Ax-F), 27 femoro-femoral bypasses (F-F) and 47 aorto-femoro-femoral bypasses (Ao-F-F). The average age was 75.8 years in Ax-F and 73.8 years in F-F. These were significantly higher than that of Ao-F-F (70.8 years). In addition, the rate of limb salvage in Ax-F was 85%, and this group had more critical cases than the other two groups. The cumulative primary patency rate and survival rate at 5 years were 64.4%, 20.8% (Ax-F), 65.9%, 51.1% (F-F) and 96.5%, 70.4% (Ao-F-F) respectively. The late results of Ao-F-F were comparable to direct aorto-femoral bypass procedures performed in our institution during the same period. On the contrary, the results of Ax-F and F-F were discouraging. We suggest that EAB should be selected for high risk, limb salvage cases and in particular, Ax-F and F-F should be limited to patients with nonphysical acting. We are opposed to appealing for an extended indications of EAB and it should not be regarded simply as a low-risk substitute for aorto-femoral bypass.
