Comparative study of the endovenous laser coagulation with 1.47 and 1.94 μm clinical effiscacy

There are presented results of clinical effectiveness comparative study of use endovenous laser coagulation with wavelengths of laser light λ=1.47 and 1.94 μm for treatment of varicose veins. Studies have shown that EVLT with a wavelength of λ= 1.94 μm is accompanied by significantly less intraoperative pain syndrome and the risk of skin hyperpigmentation in the target vein projection. A lower penetration depth at wavelength λ= 1.94 μm reduces the risk of thermal damage to the nerve trunks near the target vein.
