用波长为308nm的准分子激光照射试管内及离体动脉内血栓和主动脉壁。在光斑大小及脉冲频率不变情况下,改变单脉冲能量及脉冲次数,后经肉眼观察和组织学检查评价结果。结果表明:①准分子激光能有效地消融血栓;总能量不变时,消融深度
In vitro and in vivo arterial thrombosis and aorta walls were irradiated with an excimer laser at a wavelength of 308 nm. Under the condition of constant spot size and pulse frequency, the energy of single pulse and the number of pulses were changed, and the results of visual inspection and histological examination were evaluated. The results show that: (1) excimer laser can effectively ablate thrombus; when the total energy is constant, the ablation depth
