Background

Varicose vein of lower limb is a common vascular surgery disease in general clinical surgery, belongs to the clinical symptom of chronic venous dysfunction of lower limb, is caused by backflow caused by venous valve insufficiency, and the clinical symptom mainly shows that leg is sore and swollen, itching of foot boot area, even venous rupture bleeding and the like occur, and the incidence rate is high. Varicose veins in the lower extremities, also known as chronic venous insufficiency of the lower extremities, are of two types: varicose veins in the lower extremities and dysfunction of the deep venous valves. The clinical symptoms are that the superficial veins of the lower limbs flex and expand, long-term varicose veins can cause local pain, skin pigmentation, ulceration, lower limb swelling, limited movement and the like, and the life and work of patients are seriously affected. Surgery is the primary means of treating varicose veins. The traditional superior ligation and segmental exfoliation of the great saphenous vein has large wound and long clinical recovery time, and with the rapid development of a minimally invasive technology, microwave treatment is selected in the treatment of the great saphenous vein of lower limb, so that the traditional superior ligation and segmental exfoliation method has the advantages of small wound, good curative effect and low recurrence rate, and gradually replaces the traditional developmental operation to become a main operation for treating the great saphenous vein.
