Paper Abstract

The interaction of laser radiation with blood vessels is treated analytically using a model based on experimental data by considering the steady-state approached by the system. The factors controlling the relative performance of different lasers in closing vessels are uncovered and discussed. Carbon dioxide, Argon and Nd:YAG lasers are compared. An explanation of laser stimulated vessel wall disruption is found. Evidence suggests that coagulation is enhanced by the local presence of radiation energy. The theory shows why Argon laser radiation has a more destructive effect on the perivascular tissue than Nd:YAG laser radiation in closing vessels of the same size.
