During the EVLT procedure, the surgeon uses ultrasound to find the vein to be treated. The veins that can be treated are the main venous trunks of the legs:
- Great Saphenous Vein (GSV)
- Small Saphenous Vein (SSV)
- Their major tributaries such as the Anterior Accessory Saphenous Veins (AASV)
difference between 1470nm and 1940nm endovenous laser
The 1470nm laser wavelength of the CHERYLAS endovenous laser machine is effectively used in the varicose veins treatment, 1470nm wavelength is preferentially absorbed by water 40 times more than a 980-nm wavelength, the 1470nm laser will minimize any post-operative pain and bruising and the patients will recover quickly and back to daily work in a short time.
Now Dimed Laser developed 1940nm for EVLT, the Absorption coefficient of 1940nm is higher than 1470nm in the water.
Cherylas 1940nm varicose laser is able to produce similar efficacy to 1470nm lasers with far less risk and side effects, such as paresthesia, increased bruising, patient discomfort during and immediately following treatment, and thermal injury to the overlying skin. When used for endovenous coagulation of blood vessels in patients with superficial vein reflux.
