Some varicose patients do not have discomfort such as limb soreness and swelling, so they do not take the initiative to treat them, but with the development of the disease, the following complications may occur: a. Thrombotic superficial phlebitis: blood flow in varicose veins is slow, which can easily cause thrombosis, and can be accompanied by infectious phlebitis and perivenous inflammation of varicose veins, with redness, swelling and pain, and after the inflammation subsides, there are often local hard nodes and skin adhesions. After the inflammation subsides, there is often local hard nodes and skin adhesions. Antibiotics and local hot compresses can be used to treat the varicose veins. Second, ulcer formation: the ankle boot area is a part of high venous pressure, and there is a constant traffic vein, once the valve function is broken nutritional changes, easy to cause long-lasting ulcers after the skin damage rupture, mostly complicated by infection, often recur after healing. Treatment: wet dressing for trauma, elevate the affected limb to facilitate reflux, and surgical treatment should be done after the surrounding inflammation is reduced, and the trauma can heal quickly after surgery. Three, varicose vein rupture bleeding: Most of them occur at varicose vein aneurysm-like changes. It can be manifested as subcutaneous stasis or external bleeding when the skin is broken, and the bleeding is fast due to high venous pressure. Elevation of the affected limb and local pressure bandages can be used to stop the bleeding, and if necessary, sutures can be used to stop the bleeding, and then surgical treatment can be done later. Fourth, the calf skin eczema-like changes: late lesions of the lower leg with skin flaking, itching, pigmentation, eczema and other changes, affecting the quality of life. V. Deep vein thrombosis: varicose veins in the lower limbs are independent risk factors for deep vein thrombosis. If edema appears in the limbs and does not subside even in the morning, accompanied by limb swelling and discomfort, one should be alert to whether there is deep vein thrombosis and should brake and immediately go to the hospital for venous ultrasound examination. If the diagnosis and treatment are not timely, pulmonary artery thromboembolism may occur, and in serious cases, sudden death may occur.
