Vascular Procedures and Complications

Axillobifemoral bypass (AxBFB) is considered an inferior operation because of comparatively poor long-term results. One factor that has not been considered in the literature is whether or not the operation is performed electively or for acute ischemia (< 24 hours duration). This may be a more important predictor of poor results than previously recognized. During the last 10 years, we have performed 59 AxBFB. In Group A, 41 patients (mean age 71) underwent elective AxBFB and in Group B, 18 patients (mean age 65) had emergency AxBFB. Indications for surgery in Group A were limb-threatening ischemia (30), infected aortic graft (5), and severe claudication (6); in Group B, indications for surgery were acute limb ischemia (16), and aortoduodenal fistula (2). Primary patency (p < 0.002), limb salvage (p < 0.002), and survival (p < 0.03) were significantly better in Group A versus Group B. We conclude that an AxBFB performed electively provides satisfactory palliation of severe vascular disease in high-risk patients. The indications for operation and timing of the operation may explain the widely disparate clinical results reported in the literature.
