In the case of varicose veins they use the EVLT method to exclude the pathological area of the vein from the blood flow; this provides the necessary thermal damage to the vein wall to start the process of fibrous transformation and its resorption.

The technique of EVLT consists of introducing a radial fiber through a catheter into the lumen of the pathological vein. After positioning the fiber in the vein under ultrasound control, an anesthetic is injected into the perivenous space.

Next, the laser light is activated and the process of thermal treatment of the vein wall is initiated in order to coagulate the vein.

The advantages of using 1.94 μm for EVLT:

• Compared to 1.47 μm, leads to a reduction in the duration of postoperative pain and the administration of pain medications

• Efficient coagulation of great saphenous vein trunks at lower energy parameters compared to devices at 1.47/1.55 μm wavelength
• Low-energy operation reduces the risk of fiber breakage and extends its life for use on multiple veins in a single session
• EVLT can be performed in superficial veins and varicose knots due to the absence of overheating of adjacent tissues caused by the shallow depth of radiation penetration into the tissue at 1.94 µm
