What is saphenous varicose vein? Saphenous varicose vein is a common disease in vascular surgery, which can develop all year round, mostly due to the loss of the “one-way valve” of the saphenous vein, which causes blood to flow backwards, resulting in stasis in the saphenous vein, showing a worm-like vein mass or greenish-purple line vessels. When the disease is serious, the ankle will become black and ulcerated, and the bleeding will not stop easily, which seriously affects people’s health. The incidence of varicose veins in China is increasing year by year, and the incidence of the population has a tendency to be younger. Epidemiological statistics show that the incidence rate is about 10% or more, and its very high incidence rate has seriously affected people’s health.
