Use and durability of femoral vein for autologous reconstruction with infection of the aortoiliofemoral axis

Abstract

To analyze early and late mortality, venous morbidity, reinfection, and freedom from reintervention after using the femoral vein (FV) for vascular reconstruction with infection of the aortoiliofemoral axis. By reviewing our database, 86 patients could be identified with implantation of FV grafts in infected fields between November 1995 and July 2012. The patient records were retrospectively analyzed and follow-up information obtained from patients or their general physician. Seventy-one patients presented with prosthetic graft infection and 15 with an infected aneurysm. For data analysis, patients were divided into an aortoiliac (n = 67) and a femoral group (n = 19). Study end points assessed were early and late mortality, incidence of deep vein thrombosis of the FV donor limb, graft patency, limb salvage, reinfection, and freedom from reintervention. Sixty-seven aortoiliac reconstructions were performed using 84 FV grafts with an operative mortality of 9%. After a mean follow-up of 45 months, survival, patency, limb salvage, and freedom from reintervention were 45%, 97%, 94%, and 91%, respectively, at 5 years. Twenty FV grafts were employed for 19 femoral reconstructions with an operative mortality of 10.5%. Here, mean follow-up was 35 months and survival, patency, limb salvage, and freedom from reintervention were 29%, 87%, 93%, and 81%, respectively, at 5 years. Specimen culture confirmed Staphylococcus (epidermidis and aureus) as the predominant microorganism. Venous morbidity after FV harvest showed an incidence of deep venous thrombosis of 13.7% for popliteal and 10.6% for tibial level at a follow-up of 24 months with only mild clinical symptoms (21% limb swelling). Vascular reconstruction using autologous FV in arterial and graft infection of the aortoiliofemoral axis provides durable long-term results with acceptable mortality and morbidity.
