Non-surgical treatment of varicose veins: 1. Compression therapy method The use of elastic stockings, the use of external pressure to reduce the edema generated during exercise. Theoretically, the pressure of elastic stockings is greatest at the ankle and gradually decreases upward. It is usually best to wear elastic stockings up to the thighs, and elastic stockings are best worn early in the morning before waking up and taken off until after going to bed at night. If the patient has a leg ulcer due to venous hypertension, it should respect the physician’s instructions to take antibiotics and diuretics and supplemented with special Eisai treatment. 2. Sclerotherapy injection sounds like a good technique. No anesthesia, no incisions, and low cost, however, there are great risks associated with sclerotherapy injections. First, if the sclerosing agent injection fluid leakage, can lead to skin necrosis; second, once the sclerosing agent into the deep vein, can lead to thrombosis, serious cases of pulmonary embolism. In recent years, the international sclerosing agent injection has made a series of improvements, such as: the emergence of microfoam technology (microfoam). It can make the occlusion effect better while reducing the concentration and dosage of sclerosing agent, which greatly avoids the complications in the past, however, the effect of sclerosing agent injection for the treatment of saphenous vein trunk is very poor, and it is not widely used in the clinic due to the high recurrence rate and the factors of domestic medical environment. Surgical treatment of varicose veins: 1.Surgical extraction surgery An incision is made in the groin to cut off the ligature or extract the saphenous vein, which requires semi-body or general anesthesia and requires 2-3 days of hospitalization. If the varicose vein is too strong, several small wounds may be required to remove the varicose vein in one section, which is a complete treatment but has the disadvantage of subcutaneous bruising and painful wound. 2.Minimally invasive aspiration technique is designed for patients with extensive varicose veins in the lower legs. A subcutaneous light source is used to locate the varicose veins, and then a suction system is used to remove the varicose veins. This technique requires only 2-5 small incisions in the calf to solve the problem of varicose vein clusters in the calf. 3.Laser endovenous closure procedure is a laser that uses a special wavelength. This technique avoids some of the complications associated with saphenous vein aspiration, such as hematoma and saphenous nerve injury. Other techniques that are similar to the laser are: radiofrequency closure and cryo-closure. These three techniques have in common the avoidance of saphenous vein stripping, however, they cannot help with the varicose veins in the lower legs and often have to be combined with traditional stripping surgery, and the recurrence rate of laser treatment is higher in clinical practice. In addition, discomfort due to striae phlebitis in the thighs one week after laser treatment is one of the complaints of many patients. The treatment of varicose veins in the lower extremities is a comprehensive treatment that includes drugs, physical therapy, and surgery. No one treatment can solve all problems. The doctor can develop an individualized treatment plan based on the patient’s condition.
