Varicose veins in the lower extremities are a common disease with a high incidence in adults, mostly in people who stand for long periods of time or have heavy workloads. The clinical manifestation of varicose veins is the gradually aggravated “bruises” in the legs, like “earthworms”, and some patients have itchy skin, sore and heavy legs, and weakness of walking, etc. In serious cases, the skin of the lower leg may become purple and black, or even ulcerated, which is not healed for a long time, commonly known as “It affects patients’ physical and mental health and daily life. The traditional methods of treating varicose veins include conservative treatment and surgical treatment. Conservative treatment mainly involves taking medicine and wearing elastic stockings, but it can only relieve the symptoms and cannot make the varicose veins disappear. Especially in the hot summer, elastic stockings become a source of pain. Surgical treatment can solve the varicose veins fundamentally, but even with the least traumatic surgical method nowadays, it still requires a small incision in the leg and cannot avoid the problem of surgical scar, which is unacceptable for the ladies who love beauty. With the rapid development of medical technology, the treatment of varicose veins in the lower extremities has entered the era of minimally invasive, and laser endovenous cauterization and sclerotherapy injection are among the most representative minimally invasive treatment modes. Endovenous laser treatment can be performed by puncturing the varicose vein with the help of ultrasound and inserting a thin laser fiber to the root of the saphenous vein under the guidance of a catheter, and applying the conduction characteristics of the semiconductor laser to the vein wall to precisely destroy the endothelium of the vein and achieve the goal of vein fibrosis and vascular closure. Although the laser treatment is still performed under anesthesia, the shortened procedure time reduces the duration of anesthesia and the amount of anesthetic drugs used. This procedure is highly safe, less invasive, less bleeding, no scarring, rapid postoperative recovery, significant efficacy, and low recurrence rate. Varicose vein sclerotherapy adopts German imported polydocanol foam sclerosing agent, which is injected locally into the superficial varicose veins within the skin and under the skin to cause sterile inflammation and atrophy and occlusion of the varicose veins to achieve both therapeutic and cosmetic effects. This method can be used repeatedly and is useful for all kinds of varicose veins including capillary dilation or reticular vein dilation, especially for young patients with high aesthetic requirements. The whole process is like playing an intravenous needle on the leg, easy to operate, short duration, only about half an hour, no pain, no anesthesia, no hospitalization, sure efficacy, fast recovery, few complications, does not affect the patient’s normal life, and low cost, beautiful, so gradually by the doctors and patients pro-gaze.
