[Effects of the argon laser on atheromas. Preliminary study on post-mortem arterial samples].
The effects of argon laser radiation of human atheroma were studied in vitro. Lesions produced were craters from total tissue volatilization surrounded by a thin zone of coagulation. The degree of tissue destruction was related to the energy used and the direction of the laser beam in relation to the atheromatous stenotic lesion. These findings confirm that it is possible to destroy the atheroma under controlled conditions, but at the non-negligible risk of perforation. By allowing visual control, the angioscope should ensure increased safety in use and provide hope for future applications of this method by the percutaneous route in the treatment of established atheromatous disease.
