Distal popliteal and tibioperoneal transluminal angioplasty: long-term follow-up.
The long-term efficacy of percutaneous transluminal angioplasty (PTA) for treatment of occlusive lesions involving arteries below the knee was evaluated in 168 consecutive patients. The procedure was preceded by intraarterial thrombolysis in 33 patients with failing femorodistal grafts. Indications were disabling claudication in 40 cases (24%), acute ischemia in 18 (11%), rest pain in 49 (29%), and tissue necrosis in 61 (36%). Angioplasty of tandem femoral and/or iliac lesions was performed in 58 cases (34.5%). Major complications were observed in 19 patients (11.3%) and minor complications in 12 others. Five patients died within 30 days (3%). Mean follow-up was 26.1 months (range, 4-72 months). Major amputation was required in 26 cases (15%). The cumulative clinical success at 3 years was 83% for a single stenosis, 76% for multilevel lesions, 44% following lytic therapy, 36% for segmental occlusions, and 14% for anastomotic stenoses. Infrapopliteal PTA is useful in selected patients. Factors associated with poor long-term patency include a single patent tibial artery (P = .039), acute ischemia (P = .03), anastomotic stenosis (P = .01), and, possibly, complete occlusion prior to treatment (P = .091).
