(1) Laser thermo-optical angioplasty in totally occluded peripheral arteries permits recanalization of lesions which would have otherwise required surgical bypass procedures. (2) Technical success was accomplished more frequently in patients with shorter occlusions. The technical success range in totally occluded blood vessels is 70-80%. (3) Clinical success in the peripheral circulation requires balloon angioplasty in most cases. Laser angioplasty has yet to be evaluated as monotherapy. (4) The combination of laser and balloon angioplasty has not decreased the restenosis rate from that seen with balloon angioplasty alone. (5) Restenosis rate was not influenced by lesion length. (6) In a significant number of patients with a totally occluded vessel a surgical procedure was avoided by performance of a percutaneous therapy.
(1) 激光热光血管成形术可使完全闭塞的外周动脉再通，否则这些病变可能需要进行外科搭桥手术。(2) 闭塞时间较短的患者技术成功率更高。完全闭塞血管的技术成功率范围为70%-80%。(3) 在外周循环中，大多数情况下临床成功需要进行球囊血管成形术。激光血管成形术尚未作为单一疗法进行评估。(4) 激光和球囊血管成形术联合使用并未降低与单独使用球囊血管成形术相比的再狭窄率。(5) 再狭窄率不受病变长度影响。(6) 在大量完全闭塞血管的患者中，通过进行经皮治疗避免了外科手术。
