間歇性跛行例に対するレーザー治療

Percutaneous Transluminal Laser Angioplasty (PTLA) was performed on 132 peripheral arterial lesions (51 occlusions, 81 stenoses ) from March, 1985 through March, 1993. The results and limitations of PTLA were evaluated. The total initial success rate was 90.9% (120/132). Failed cases included six femoropopliteal long lesions and two iliac severe calcified lesions. The cumulative patency rate was 89.7% totally, 91.4% in the iliac lesions, 85.8% in the femoropopliteal lesions and 100% in the below knee lesions. We have no major complications due to laser irradiation. Dissection owing to added balloon PTA may influence long-term patency rate. PTLA has limitation in the case of hard lesion, long lesion, with DM etc. However, it has expanded the indication of PTA and produced a better long-term patency rate. In conclusion, PTLA is a valuable method in treating peripheral arterial occlusion.
