Superficial varicose veins in the lower extremities are one of the most common peripheral vascular diseases, and treatment includes conservative and surgical treatments. While conservative treatment can slow down the progression of the disease, surgical treatment is the way to cure the disease. Traditional surgery has many incisions, is traumatic, and the patient’s recovery is relatively slow and unattractive. With the progress of science and technology, more and more minimally invasive methods are used in clinical practice. They are introduced as follows: 1. Sclerotherapy with compression injection: It is suitable for small varicose veins less than 4mm in diameter. The complications include pigmentation, skin necrosis at the injection site, new capillaries and allergic reactions. Among them, the long-term efficacy is inaccurate, and its indications need to be strictly grasped. 2.Intracavitary laser treatment and radiofrequency treatment: it is mainly a treatment method for the main trunk of saphenous vein, which has the advantages of less trauma, less incision and less complications, but the efficacy is not exact for severe varicose masses, and traffic branch reflux. At present, CEAP is considered to be used alone only when the classification is below C2, and combined with other methods if the condition is more severe. 3.Transilluminated direct vision spinotomy: This method is suitable for larger varicose vein masses. However, there is a possibility of skin damage due to excessive negative pressure during the operation, and for patients with combined thrombophlebitis or previous sclerotherapy, it is difficult to break them up with the rotary cutter and conventional stripping is required. The disadvantage is that the postoperative subcutaneous pigmentation time is slightly longer. 4.Subfascial endoscopic traffic branch surgery: that is, the traffic vein is disconnected under the lumpectomy using ultrasonic knife. Since the ligation of the traffic branch vein is especially important to prevent postoperative ulcer non-healing and recurrence, and this method can directly deal with the traffic branch vein in the potential cavity of deep fascia, the field of view is clear, and the vein is searched for and dissected more precisely, so it has advantages that cannot be compared with traditional methods. It is especially suitable for patients with CEAP classification of C3 or above. Overall, the treatment of superficial varicose veins in lower extremities is a comprehensive treatment, and minimally invasive treatment is a trend, but no minimally invasive method is perfect yet, and all of them have their own limitations and complications. Therefore, each patient should understand his or her condition in detail, let the specialist develop an individualized treatment plan, and choose the appropriate treatment method according to the patient’s different conditions in order to achieve the best treatment effect.
