Management of vascular infection in the groin

We performed this retrospective study in order to evaluate the effectiveness of different surgical methods in the treatment of inguinal vascular infections. Fourteen consecutive patients underwent surgical treatment of such infections from 1996 through 2004 in our clinic. The mean age was 52 +/- 16 years. Seven of the 14 patients underwent emergency operation due to bleeding or acute ischemia. The events that caused inguinal infection were synthetic graft implantation in 8 patients, gunshot injury in 1, arterial catheterization in 2, femoropopliteal saphenous vein bypass operation in 1, and motor vehicle accident with abdominal wall laceration in 2. The most common infecting pathogen was Staphylococcus aureus (7 patients). Sixteen operations were performed in 14 patients. These operations included lateral femoral bypass (5), obturator bypass (5), revascularization with homograft (5), and femorofemoral bypass (1). All inguinal infections were completely cured after surgery. Early complications included poor wound healing (4 patients), minor amputation (1 patient), and extension of infection to the distal anastomosis of the obturator bypass and false aneurysm formation (1 patient). Late complications were acute homograft occlusion of a femorofemoral bypass and thrombosis of a below-knee lateral femoral bypass. There was no operative or late mortality. All patients were followed up for a mean of 48.1 +/- 21.9 months. We did not encounter any aneurysmal degeneration, rupture, or reinfection in homograft patients during follow-up. We conclude that vascular infections of the groin can be cured by proper selection and application of one of the above techniques.
