Abstract
The authors summarize their experience in the use of Nd-YAG laser in chronic occlusion of lower limb arteries. Percutaneous transluminal laser angioplasty (PTLA) with laser-heated metal and sapphire tips were used as an adjuvant to conventional balloon angioplasty. In cases of reocclusions, endovascular stents were implanted. Laser recanalization was performed in 46 arteries (iliac, superficial femoral, and popliteal). Indications for the procedure were: limb salvage, claudication below 100 m, and temporal or rest pain. Initial clinical and hemodynamic improvement was observed in 37 (80%) patients. Four perforations occurred without clinical sequel. The one-year cumulative clinical patency was 27 (58%) of the 46 lesions. PTLA may be appropriate for high-risk patients, who are unsuitable for surgical reconstruction because of the concomitant diseases. The combination of laser recanalization and implantation of vascular stents may be a promising method in the management of limb ischemia.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
