Patients with varicose veins who exhibit localized darkening of the skin are considered to be a sign of localized skin dystrophy. Because of severe varicose veins, vasodilatation can affect the blood supply and oxygen deficiency of the skin, so hyperpigmentation and desquamation can occur. As the condition evolves to form a visible ulcer surface, the patient may also experience pain as well as recurrent oozing and bleeding. If the ulcer surface gradually expands, it can also involve the superficial tortuous vessels and even lead to the rupture of the varicose vein mass and induce bleeding. Therefore, varicose veins should be treated early. Mild cases can be treated by conservative treatment methods such as compression stockings and sclerotherapy injections; for severe varicose veins, the most effective treatment option is surgery.
