The majority of superficial varicose veins in the lower extremities are saphenous varicose veins (a few are small saphenous varicose veins or both small and large saphenous varicose veins), which are extremely common clinically, with about 25% of women and 15% of men worldwide suffering from these diseases, the onset of which is often related to genetic factors and can be triggered by prolonged standing and heavy work. 1, the etiology includes: (1) weakness of the vein wall; (2) venous valve insufficiency leading to blood reflux; (3) elevated pressure in the superficial veins, such as pregnancy. 2, the main clinical manifestations: for the lower extremities, especially in the calf, superficial veins bulge, expand and bend, and even curl into a mass, soreness and swelling, weakness, swelling of the foot after standing for a long time, and in the late stage, there are often brown pigmentation and eczema on the skin of the calf and ankle. If the time is too long or improper treatment can lead to lower limb edema, local tissue hypoxia, causing skin keratinization, desquamation, minor trauma can lead to poor healing, delayed for a long time chronic ulcers, commonly known as “old rotten leg”. About 20-25% of lower limb venous diseases combined with lower limb ulcer formation. Since varicose veins of lower extremities are a common disease, there are a lot of propaganda and advertisements about the treatment methods of this disease in various newspapers and media, which are of good and bad quality, and doctors will also make different suggestions due to different levels of understanding, which is difficult to choose as a patient. Choosing the right treatment method should be combined with different etiology, pathogenesis, clinical manifestations and the patient’s general condition and treatment requirements. 3, the treatment methods of the disease are: (1) conservative treatment: for pregnancy, early clinical manifestations of the disease is mild, advanced age or poor general condition can not tolerate surgery, the patient should be appropriate bed rest, elevate the affected limbs and avoid long-term standing. Medical elastic stockings have good elasticity and binding force, which can reduce the superficial venous hypertension produced by muscle contraction during activity, and cooperate with appropriate medication to increase the elasticity of the venous wall and reduce exudation; however, patients with combined lower limb atherosclerosis occlusive disease should use elastic stockings with caution, and elastic stockings should be worn during the day, and removed at night and sleep in a slightly elevated position of the lower limb. (2) local sclerotherapy injection: the so-called “injection”, “injection therapy”, “liquid knife”, etc., is a non-cause-specific treatment, high recurrence rate, more complications (such as sclerosing agent allergy, loss of peripheral nerves and cause intractable pain in the limb, leakage of sclerosing agent into the subcutis leading to skin and subcutaneous fat necrosis and formation of refractory ulcers, or even cause deep vein thrombosis), only as an adjuvant treatment for patients with mild local recurrence after surgery. (3) Surgical treatment: high ligation of saphenous vein + spot stripping of superficial varicose veins, this procedure is suitable for most patients with varicose veins, the surgery is performed at the inguinal area where the saphenous vein merges into the deep vein (femoral vein), high ligation of the saphenous vein and its branches, segmental aspiration of varicose vein masses in the lower limbs, the treatment is complete and the recurrence rate is low. Saphenous vein high ligation + stripping + deep vein valve repair is suitable for some patients with deep vein valve insufficiency, and simple saphenous vein high ligation + stripping is not effective. (4) Minimally invasive treatment: It is a minimally invasive treatment method for saphenous varicose veins developed in recent years, such as laser, radiofrequency electrocoagulation, etc. It is very traumatic, with only tiny skin puncture points, fast recovery and short hospitalization time, but it is only suitable for some patients. Our department has accumulated rich experience in the treatment of varicose veins in the lower extremities. We make a comprehensive assessment of individual patients’ conditions and choose a reasonable surgical method, and combine traditional surgical methods with minimally invasive laser treatment, which can achieve the requirements of radical treatment and low recurrence rate without losing aesthetics, with the advantages of small trauma and fast recovery after surgery, and the average hospital stay is only 4 days, which greatly reduces patients’ pain and economic burden.
