Varicose veins are caused by tortuous blood vessels in the lower extremities and may also be associated with itching, hyperpigmentation and ulcer formation in the lower extremities. The traditional procedure is a high saphenous vein ligation and segmental stripping procedure, which costs around $7,000 overall and is preceded by routine tests, including electrocardiogram and vascular ultrasound. During the procedure, multiple incisions are made in the lower extremities to ligate the saphenous vein and remove the tortuous vessels in sections. After the surgery, there may be oozing from the wound, and the wound will be scarred more after healing, which affects the aesthetics. Minimally invasive treatment is also available, which is an endovenous laser closure procedure, in which the endothelium of the saphenous vein is cauterized through a puncture on the body surface of the lower extremity, allowing the vessel to close on its own. After the procedure, the patient will feel significantly less pain and also have significantly less scarring in the lower extremity, which is more aesthetically pleasing, but the cost is more, which may cost about 10,000 yuan.
