Long-term results of transluminal angioplasty of the iliac and femoral arteries.

• One hundred forty-eight iliac artery and 103 femoral artery stenoses were successfully treated using percutaneous transluminal angioplasty (PTA) in 239 patients between January 1978 and January 1981. Patency rates for iliac PTA were 93.4% after one year, 87.2% after two years, and 79.4% after three years. Patency rates for femoral PTA were 79.6% after one year and 74.9% after two years. The PTA procedure can be performed successfully for both claudication and salvage, and its results compare favorably with those of bypass surgery for the treatment of peripheral vascular lesions.
