激光束心肌打孔改善心肌微循环动物实验研究

Experiments on improvement of myocardial microcirculation by laser myocardium

心血管疾病是目前死亡率较高的一种疾病。现在美国、苏联和日本等国都在进行激光心血管疾病的实验研究。激光心肌血管重建术已经取得了很大进展。我国从1987年开展了激光束心肌打孔改善心肌微循环的动物实验研究。激光心肌血管重建术系采用激光束辐照心肌表面,从心外膜打出细孔直达心内膜的手术,不必切开心脏,它优于通常的“搭桥”手术。本文报道采用CO2激光束,以猪、狗、羊等为对象进行激光心肌血管重建术,以改善心肌微循环的实验结果。

Myocardial revascularrization by laser is a kind of operation which uses laser beam to converge on the surface of myocardium and punch from epicardium to endocardium. The blood in heart can directly make nutrition for myocardium. It is not neeessery to incise heart and put into bridging operation. Experimental results are reported about punching minute holes in myocardium of animals (i. e pig, dog, or sheep) by CO2 laser to improve the myocardial microcirculation.
