Laser angioplasty is an effective tool to revascularize peripheral artery disease, but the major limitation is a high restenosis rate. Our experience with the hot tip laser system has shown a high primary success, 59-73% of the arteries were patent at 18 months, although 21% resulted in severe restenosis. The excimer laser seems to have a better long-term patency. Histology of restenosis specimens removed by atherectomy, shows the key role of the smooth muscle cells in this process.

Abstract
Laser angioplasty is an effective tool to revascularize peripheral artery disease, but the major limitation is a high restenosis rate. Our experience with the hot tip laser system has shown a high primary success, 59-73% of the arteries were patent at 18 months, although 21% resulted in severe restenosis. The excimer laser seems to have a better long-term patency. Histology of restenosis specimens removed by atherectomy, shows the key role of the smooth muscle cells in this process.
