<p>The invention relates to laser medicine, in particular to dermatology and can be used for curing hemangioma, curing and preventing a venous distensibility and other vascular diseases. Said invention enhances the efficiency of coagulation of blood vessels and reduces probability of traumatism of surrounding tissues. The inventive method consists in applying a laser pulse irradiation having a wave length within a range of 500 - 600 nm and an energy density equal to 10 J/ cm2, to a blood vessel during 10 ms. At the same time, the blood vessel is exposed to the action of an additional irradiation having at least one different wave length ranging from 800 to 1400 nm and the energy density not less than 100 J/cm2. The energy density and the exposure duration are selected in relation to the dimensions of the coagulated vessel. The irradiation can be produced in the form of single pulses during not more than 10 ms, or in the form of nanosecond pulse packet whose duration does not exceed 10 ms.</p> |
