Routine revascularization with resection of infection femoral pseudoaneurysms from substance abuse.
Infected femoral artery pseudoaneurysms in narcotic addicts present challenging management options. Our policy of routine revascularization is based on the concern that a high rate of amputations must follow ligation and resection alone or with selective delayed revascularization. Fifteen of 16 patients with infected pseudoaneurysms of femoral arteries, treated with resection and bypass grafts, were observed from 1 to 44 months. Obturator bypass grafts were used in 10 patients, iliac-femoral grafts in three, axillopopliteal in one, and right external iliac crossover to left popliteal in one patient. One limb, unsalvageable at presentation, was amputated primarily, along with resection of pseudoaneurysm and femoral artery ligation, without bypass grafting. One iliac-femoral graft became infected and then thrombosed 4 months after operation. Unsuitable distal arteries and impending necrosis led to above-knee amputation. One late failure among 15 revascularization attempts (7%) is significantly lower than the 11% to 33% amputation rates reported in the literature with resection of pseudoaneurysm alone and delayed selective revascularization. The other 14 patients had functioning limbs without claudication or rest pain. Our experience indicates that revascularization at the time of resection of infected pseudoaneurysm offers better prospects for limb salvage.
