Abstract

Balloon angioplasty, while generally successful as a revascularization procedure, has the major drawbacks of abrupt reclosure and chronic restenosis. These problems may be related, at least in part, to a large thrombogenic surface and to abnormal blood flow patterns caused by disrupted vessel wall elements impinging on the lumen following angioplasty. Laser balloon angioplasty (LBA), a method whereby the vessel wall is heated during balloon inflation by a Nd-YAG laser coupled to an optical fiber terminating within the balloon, may help overcome these problems. The major effects of LBA appear to be a welding back of dissected flaps, reduction of the elastic recoil of the vessel wall, and destruction of smooth muscle cells within the wall, so that their exuberant cellular response to angioplasty is less likely to occur.
