Factors Influencing Early and Late Follow-up Results After Percutaneous Transluminal Angioplasty of the Lower Limb Arteries
Between 1977 and 1982 a total number of 305 percutaneous transluminal angioplasties (PTAs) of the lower limbs were performed in 254 patients using Grüntzig balloon catheters . Of these 252 were carried out for stenoses or occlusions in the femoral or popliteal artery and 53 for isolated iliac artery stenoses. In 15 patients (9 femoral, 6 iliac) PTA was performed on both sides; in 36 patients (30 femoral, 6 iliac) it was carried out because of a reocclusion after an initially successful PTA. Follow-up examinations including clinical evaluation, Doppler ultrasonic pressure measurement, and segmental oscillography were performed prospectively 3, 6, 12, 24, 36, and 48 months after PTA. A criterion for the success of PTA was that it reduced arm-ankle pressure difference by half 1–2 days after PTA. Beginning 2 days before PTA, all patients received acetyl salicylic acid 1.0g/day until peroral anticoagulation, started the day after PTA, was therapeutically effective, and no contraindications to anticoagulation (55 patients) were present.
