Transluminal catheter dilatation. Indications, technical aspects, results.
After 18 years of PTA experience, the results of a prospective study concerning the follow-up patency rate is demonstrated. The best results were seen in patients with claudication (1011) and treatment of iliac or superficial femoral artery stenoses and occlusions in the superficial femoral artery smaller than 12 cm. The 5 years patency rate in patients with claudication was 85 to 89%, and 65 to 72% in 491 patients with rest pain or gangrene. The primary and late results in patients with superficial femoral artery occlusion of more than 12 cm in length were not as good. In patients with claudication (82) the primary success rate was only 68%, but the follow-up patency rate was nearly as good as in the others. Patients with gangrene and occlusions of more than 12 cm showed only in 52% good primary success and only a patency rate of 30% out of all patients after 5 years. In 42% of this group PTA was a limb-saving procedure. Special details of technique and indications are discussed.
