[Changes in the blood vessels of rabbits exposed to a CO2 laser beam]

The main object of the experimental research was to study the conditions of irradiation of blood vessels with CO2 laser beam causing their coagulation. It is shown that in coagulation of blood vessels with reliable obliteration of their lumen coagulation necrosis of the wall occurs along the whole circumference of the vessel. Coagulation of blood vessels depends on their diameter and the structure of their wall and the blood flow rate in them. The CO2 laser beam does not cause coagulation of arteries with a diameter of more than 1 mm in maintained flow of blood in them.
