SHOULD PERCUTANEOUS TRANSLUMINAL ANGIOPLASTY BE RECOMMENDED FOR TREATMENT OF INFRAGENICULATE POPLITEAL ARTERY OR TIBIOPERONEAL TRUNK STENOSIS

Purpose: The purpose of this study was to determine the effectiveness of percutaneous transluminal angioplasty (PTA) for treatment of patien ts with localized stenosis of the infrageniculate popliteal artery and tibio-peroneal trunk (IGPA). Methods: The records of 25 patients unde rgoing IGPA PTA from 1983 to 1993 were reviewed. Patients underwent fo llow-up with clinical examinations, ankle-brachial indexes, Duplex sca nning, and arteriography. Demographic variables and cardiovascular ris k factors were analyzed and correlated with outcome. Results: Mean fol low-up was 44 months. With life-table analysis, clinical and hemodynam ic success was 59%, 32%, and 20% at 1, 2, and 3 years, respectively. A verage time to recurrence was 17 months. Sixteen patients required a s ubsequent procedure; two had only repeat PTA, six had repeat PTA follo wed by arterial bypass, and eight had bypass alone. The mean additiona l benefit of repeat PTA was 8 months. Eleven of the 14 patients treate d with bypass became symptom-free with patent grafts at a mean follow- up of 52 months. No risk factor was statistically significant in predi cting success of IGPA PTA. Conclusions: IGPA PTA is an expensive tempo rizing measure with a high rate of recurrence requiring subsequent int ervention. The procedure should be restricted to patients with limited life expectancy or contraindications to operation.
