Abstract
PURPOSE: We evaluated the clinical outcomes of aortofemoral bypass (AoFB) and axillofemoral bypass (AxFB) surgeries for complex aortoiliac occlusive disease (AIOD) and compared them from the perspectives of safety and efficacy. METHODS: We retrospectively reviewed 21 patients with AoFB grafting and 9 patients with AxFB grafting. The demographic information of the patients was examined, and the intra-, peri-, and postoperative results as well as long-term outcomes were evaluated. RESULTS: In the AoFB, 2 of 21 (9.5%) cases had intra- and perioperative complications, and 4 of 21 (19.0%) cases had postoperative complications; however, there were no postoperative mortalities. In the AxFB, two of nine (22.2%) cases had postoperative graft thrombosis; however, again there were no postoperative mortalities. According to Kaplan-Meier analysis, the primary patency rates in the AoFB and AxFB groups at 5 years were 94.8% and 53.6%, respectively (P = 0.001), while the limb salvage rates at 5 years were 96.4% and 92.9%, respectively (P = 0.320). CONCLUSIONS: Even though the patency rates with AxFB grafting were inferior to those with AoFB grafting, AxFB was able to achieve equivalent limb salvage rates and should thus be considered as an alternative treatment method, especially when limb salvage is a goal.
