Treatment of varicose veins in the lower extremities includes palliative, sclerotherapy and surgical treatment. Palliative therapy is mainly used for women in pregnancy, patients with early mild varicose veins and patients with poor general condition who cannot tolerate surgery. The main measures include proper rest, avoiding prolonged standing, leg hanging and heavy physical work, and using medical elastic stockings during activities. Sclerotherapy is suitable for patients with limited mild varicose veins without combined traffic branch and deep and superficial venous valve closure insufficiency, postoperative residual, and limited postoperative recurrence. The rest of the patients should be treated surgically, and surgical treatment is suitable for patients with moderate to severe superficial varicose veins with incomplete closure of deep, superficial and traffic branch venous valves and patent deep veins. The methods include traditional high ligation and stripping, traffic branch vein ligation, deep vein valve repair and minimally invasive surgical methods such as laser treatment, spinotomy, electrocoagulation, etc.
