Autogenous vein grafts for femorofemoral revascularization in contaminated or infected fields

Purpose: The purpose of this study was to determine the indications and the long-term results for femorofemoral revascularization with autogenous vein grafts (AVG) rather than conventional synthetic materials. Methods: A consecutive series of 13 men and 12 women (mean age 64 years) receiving femorofemoral AVG was collected during a retrospective review of our experience from 1979 to 1992. Sixteen of these 25 patients required revascularization for acute ischemia in the presence of potential groin contamination (group 1), and the remaining nine had frank infections involving previous synthetic grafts (group 2). New grafts were constructed with the greater saphenous vein in 23 patients (92%) and with the cephalic vein in two. Results: One patient in each group (8%) died after operation with patent grafts. Preoperative and postoperative ankle/brachial indexes (ABI) were available for 12 patients in group 1 and for seven patients in group 2. There was significant improvement in the ABI among 11 patients with ischemia in group 1 (mean 0.33 ± 0.13; p = 0.0001), whereas no change in the ABI occurred in conjunction with the replacement of patent infected grafts among six patients in group 2 (mean 0.04 ± 0.17; p = NS). One patient from each group sustained a reduction in postoperative ABI for the recipient limb despite a patent AVG. Cumulative 3-year survival and primary patency estimates for all 23 operative survivors were 63% and 75%, respectively. Late results seemed to be comparable in group 1 and group 2, but each contained too few patients for adequate analysis. Conclusions: Despite their infrequent use, AVG seem to represent a reasonable alternative to synthetic bypass for femorofemoral revascularization in patients having either contaminated wounds or established graft infections.
