There are no systematic and widespread statistical findings on the incidence of varicose veins in China. The estimated incidence of varicose veins in the lower extremities in China is about 5-10%. With the increase of health awareness, varicose veins of lower extremities have become the main disease in vascular surgery outpatient clinics or wards all over the world, whether and when surgery should be performed and what kind of surgery should be chosen have become the main problems for the majority of patients. At present, domestic surgical methods are mainly the following: 1, traditional varicose vein surgery: the main trunk of saphenous vein is stripped while multiple incisions are made to the varicose veins of the lower leg, this surgical method is long, traumatic and painful due to the incision, which makes the patient’s hospital stay generally about 7-10 days. 2. Endovenous laser closure (EVLT): It is a kind of laser that uses special wavelengths to intervene into the saphenous vein trunk through fiber optics and then perform vein closure, this technique to some extent avoids some complications caused by stripping the saphenous vein. For example, hematoma, saphenous nerve damage, etc. Other techniques that are similar to the laser are: radiofrequency closure and cryo-closure. These 3 techniques have in common the avoidance of saphenous vein stripping, fast recovery, the patient can go to the ground the next day, and short hospital stay; for varicose veins in the lower leg they often have to be combined with punctiform varicose vein removal surgery. The discomfort caused by striae phlebitis in the thighs within a week of laser treatment is also a complaint of many patients, who can generally recover after 1-2 weeks of treatment. 3. Planar suction technique (Trivex): Designed for patients with extensive varicose veins in the lower leg, a subcutaneous light source is used to locate the varicose veins and then a planar suction system is used to remove the varicose veins. This technique solves the problem of varicose veins in the lower leg by making only 2 incisions in the lower leg. However, the aspiration technique is not applicable to the trunk of the great saphenous vein. Also the planar aspiration is not strictly speaking minimally invasive, it looks like few and small incisions, but the subcutaneous trauma is greater. 4.Sclerosing agent injection: No anesthesia, no incision, and low cost. The main sclerosing agents include sodium cod liver oil acid and polyglaucine. However, there are great risks of sclerotherapy injection (although the incidence is relatively low); one is that if the sclerosing agent injection solution leaks, it can lead to skin necrosis. Secondly, once the sclerosing agent flows into the deep veins, it can lead to thrombosis and, in severe cases, pulmonary embolism. The effect of sclerosing agent injection is poor for the treatment of saphenous vein trunk, which cannot change the cause and progress of varicose veins, and it is not widely used in clinical practice due to the high recurrence rate and the factors of domestic medical environment. Some small medical institutions package sclerotherapy injection as “the latest therapy”, “thrombolysis”, “interventional conduction”, “nano therapy “and so on, with a certain degree of deception. At present, our hospital vascular surgery department thinks that foam agent is more reasonable for light stage varicose veins (aesthetic as the main purpose) or postoperative residual varicose veins adjuvant treatment. 5.CHIVA surgery: CHIVA is the French abbreviation for Cure Conservatrice et Hemodynamique de l′Insufficience Veineuse en Ambulatoire. the concept of CHIVA surgery is (1) to preserve the human saphenous vein trunk, which can be used for venous circulation and can be used as The concept of CHIVA is (1) to preserve the saphenous vein trunk of the body, which can be used for venous flow and can be used as a vascular graft for other diseases in the future; (2) to perform the procedure under local anesthesia, so that the patient can walk around after the procedure without being hospitalized for observation; (3) to be almost painless after the procedure because most of the vessels are preserved, and to avoid the problems of nerve and lymphatic reflux that may exist in other procedures. The problem is that, like the use of sclerotherapy, it does not fundamentally change the problem of blood reflux, which may lead to postoperative recurrence or reoccurrence in other areas, and is now generally considered to be used only in the case of grade 2-4 varicose veins. Vascular surgery throughout China has made great progress and achievements in the treatment of varicose veins. However, in an overview, there are still some problems in the treatment of varicose veins in China that patients need to be aware of when choosing surgery.
