Abstract

Laser application for atherosclerotic ablation is still limited. The pulsed Holmium-YAG (HO-YAG) laser has physical characteristics which may improve vascular recanalization. We therefore examined the effect of this laser on cadaver human atherosclerotic aortae, human amputated legs and atherosclerotic rabbits in vivo. The pulsed HO-YAG laser successfully ablated calcific and fibrotic aortic segments. Totally occluded arteries in amputated legs including calcified atherosclerotic lesions were successfully recanalized using 165-350 pulses of 0.35-0.4 J energy per pulse transmitted through commercially available fibre optics. Percutaneous delivery of laser energy to the descending aorta of atherosclerotic rabbits was not traumatic to the arterial wall. These results demonstrate the advantages of the pulsed HO-YAG laser to ablate fibrotic and calcific atheroma and to safely recanalize occluded arteries.
