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.

A total of 16,350 patients underwent cardiac catheterization from January 1981 to December 1987. The brachial artery was used in 10,500 patients (group I), and the femoral artery was used in 5850 patients (group II). Surgical intervention for complications was necessary in 60 (0.57%) of the group I patients and in 14 (0.23%) of the group II patients. Hand ischemia in group I and bleeding in group II were the most frequent indications for operation. Procedures performed were segmental resection, vein interposition, and long bypass in group I, and simple suture and angioplasty were performed in group II. Fifty-six patients of the total of 74 underwent early repair (within 48 hours), and 18 patients underwent delayed intervention. Only one (1.7%) of the 56 patients who had early repair had a complication. Five of the 18 patients (28%) with delayed intervention suffered significant complications. Cardiac catheterization by the brachial or femoral route has a low incidence of complications. Delayed intervention is associated with high morbidity despite adequate restoration of circulation. Although there were fewer complications in the femoral group, they were far more serious with respect to life-or limbthreatening events.
