Percutaneous transluminal angioplasty of the femoropopliteal arteries in limbs with chronic critical lower limb ischemia

• PURPOSE: The aim of the study was to evaluate the results of percutaneous transluminal angioplasty (PTA) of femoropopliteal arteries in patients with subcritical or critical lower limb ischemia. Materials and Methods: Ninety-two patients underwent 121 PTA procedures, 68 were of the superficial femoral artery (SFA), 13 of the popliteal and 40 of both arteries. Fifty-seven procedures were performed for treatment of occlusions. Eighty-four patients (94 procedures) were monitored with duplex scanning. RESULTS: Technical success rate was 88%. Primary success rates at 12 and 60 months in the whole series were 40% and 27%, respectively. The primary success rate in limbs with SFA occlusion of longer than 5 cm was only 12% after 5 years compared with 32% if the occlusion was CONCLUSION: The results of femoropopliteal PTA performed for treatment of subcritical or critical lower limb ischemia seemed to be inferior to the results of infrainguinal bypass grafting reported in literature. However, because the PTA procedure does not preclude the performance of bypass grafting, it might be an alternative to surgical intervention in limbs with stenotic femoropopliteal lesions. PTA might also be considered in patients with high surgical risk and limited life expectancy, having short occlusive lesions (< 5 cm).
