Simple varicose veins of the lower extremities are not fatal diseases and the time frame for treatment is relatively lenient. For most mild varicose veins of the lower extremities, although the clinical manifestation is only a small amount of venous tortuosity, it affects the aesthetics of the affected limb. In young women in particular, the tortuous and dilated venous masses affect the patient’s self-confidence, which in turn reduces the patient’s quality of life. Laser lower extremity vein closure is performed by directing laser energy into the varicose veins through fiber optics, which converts light energy into heat energy, causing the varicose veins to close, thrombose, and then mechanize, causing the vein masses to disappear and achieve the treatment goal. Laser treatment of varicose veins in the lower extremities is performed by introducing fiber optics into the veins through a puncture needle without cutting into the skin, thus there is no scarring caused by cutting into the skin. For women who love beauty, laser vein closure can both treat varicose veins and achieve cosmetic results to restore beauty and self-confidence.
