Varicose veins of lower extremities, also known as chronic venous insufficiency of lower extremities, mainly manifest as dilated, bulging, curled into clusters like earthworms in the superficial veins of lower extremities, generally focusing on varicose veins of lower legs, but the thighs can also be affected. The affected limbs can have different degrees of soreness, swelling, tingling, skin itching and numbness, and the symptoms are more obvious after standing or walking for a long time. If the disease is prolonged and not treated in time, the above symptoms will be aggravated and the nutritional disorder of the lower leg will appear, manifesting as rough skin, pigmentation, eczema, skin ulcers; there may also be clinical manifestations such as venous thrombosis, bleeding and obvious swelling of the lower leg, commonly known as “old rotten leg”. Skin ulcers that do not heal over the years may become cancerous; it is a common disease and a frequent disease, often with family history. It seriously affects normal life and work. Many patients, in the early stage of the disease, have been diagnosed by doctors as varicose veins of lower limbs, and further surgical treatment is recommended; in response to doctors’ suggestions, some patients have two incorrect practices: some patients do not pay enough attention to this disease, thinking that this disease is just a little bit unattractive to the lower limbs, which will not lead to any serious adverse consequences, and let the disease develop; some other patients often do not want to treat, but only have concerns. One is afraid of the pain of surgery; the other is worried that after surgery, the disease will still recur after a few years; the above incorrect approach, as the disease progresses, leading to delayed disease and aggravation of symptoms. At present, clinically, we often see that the patients who come to the hospital have severe varicose veins in lower limbs, or with rough skin, pigmentation, eczema, swollen calves, subcutaneous venous thrombosis, or even skin ulceration; this situation is basically to the late stage of the disease, if they fail to timely treatment, the consequences will be more serious. According to the clinical data, the recurrence rate of patients who undergo surgery in general hospitals is about 10%-15% or higher in five years after surgery, but the recurrence rate in our hospital is lower, about 2%-3%, due to the combination of minimally invasive microwave surgery and traditional Chinese medicine for varicose vein disease of lower limbs. Analysis of the causes of disease recurrence after surgery may be: 1, the prevention and treatment awareness of the patient after surgery is not enough, still like before surgery exercise is too strenuous improper; or long walk, long standing, long squatting, long sitting; or did not adhere to often wear medical elastic stockings, did not let the lower limb vein pressure reduction, thus prompting the disease recurrence. 2, the patient had a history of varicose vein sclerotherapy injection before surgery; 3, the physician did not fully grasp the patient’s condition before surgery, especially not for the lower extremity lesion vascular to do comprehensive and detailed detection or judgment is not accurate enough, such as lower extremity angiography, color Doppler and other imperfect examination; 4, for complex and serious patients, the surgical method taken is not thorough and effective enough; because of severe lower extremity varicose veins at the same time appear calf skin The cause of ulcers is mostly seen in venous insufficiency of lower limb valves accompanied by venous insufficiency of traffic branch, and the condition is easy to recur after surgery without targeted accurate positioning and treatment of diseased traffic branch veins. Minimally invasive surgery combined with traditional Chinese medicine is a minimally invasive comprehensive treatment that adopts advanced minimally invasive technology combined with traditional Chinese medicine to address the etiology of varicose veins in the lower limbs. Before surgery, lower extremity angiography and color Doppler examinations are routinely performed to fully grasp the patient’s condition; especially for patients with severe lower extremity varicose veins accompanied by calf skin ulcers, intraoperative color ultrasound monitoring is adopted to accurately locate and minimally invasive treatment of diseased traffic branch veins and varicose veins to significantly reduce the recurrence of disease after surgery. For patients with lower extremity varicose veins who also suffer from lower extremity skin eczema, pigmentation and skin ulcers, it is more effective to combine external and internal Chinese medicine with comprehensive treatment. Varicose vein disease of lower extremities is often aggravated with age, and it is easy to develop skin dystrophy and calf ulcers, plus there are more possibilities of age-related diseases and other diseases such as diabetes, heart, brain and lung diseases, arteriosclerosis and other diseases, which are more dangerous to life and health. Many patients who have undergone other treatments such as traditional surgery or sclerotherapy injection, and the disease recurs again after several years, take the above microwave minimally invasive combined with Chinese medicine to supplement the treatment again with remarkable effect. This method has the advantages of exact efficacy, safety, low recurrence rate, less patient pain, fast recovery and relative aesthetics. At the same time, in order to prevent disease recurrence after surgery, patients should enhance the awareness of prevention and treatment after surgery, exercise appropriately, avoid prolonged walking, prolonged standing, prolonged squatting and prolonged sitting; insist on wearing medical elastic stockings frequently to reduce the venous pressure of lower limbs; avoid greasy food, take oral Chinese and Western medicine appropriately to reduce blood viscosity and thrombosis; seek medical treatment in time if the disease is found to be aggravated.
