Varicose veins of lower limbs, commonly known as “old rotten legs”, is a common disease, the onset of which is mostly related to poor venous blood return to the lower limbs due to prolonged standing and walking, and venous stasis in the lower limbs. The main symptoms are soreness and swelling, heaviness or pain in the lower limbs, and easy fatigue. When walking or lying down, due to the squeezing effect of gastrocnemius muscle contraction, the blood is easy to return, the pressure in the veins is reduced, and the symptoms will be relieved, so it is often not paid attention by the patients. The morphology of varicose veins in the lower extremities has distinctive features and is not difficult to diagnose, but some patients are predominantly with complications, when further examination should be done to make the diagnosis of varicose veins and complications. Since varicose veins of lower extremities can be secondary to other diseases, after the diagnosis of varicose veins is established, the etiology should be further traced to distinguish whether the varicose veins are primary or secondary. After the primary superficial varicose veins are identified, tests such as superficial venous function test, traffic branch valve function test and deep venous function test are needed to identify the type of lesion and to provide proper treatment. Varicose veins in the lower extremities can be treated with open surgery, endovenous laser closure, endovenous radiofrequency closure and sclerotherapy. Minimally invasive treatment of varicose veins includes the traditional high saphenous vein ligation and stripping, which requires multiple incisions to strip the varicose veins and inevitably leaves more incisional scars, thus affecting the aesthetic appearance. At present, there are minimally invasive treatments such as modified saphenous vein ligation point stripping, percutaneous interrupted suturing, endovascular laser treatment, electrocoagulation, and radiofrequency treatment. These minimally invasive treatment methods are performed under minimally invasive puncture microincision and incisionless, so they have the characteristics of quick recovery and less scarring with minimal invasion, and are suitable for patients with low tolerance, poor physical condition and requirements for aesthetic appearance. Nowadays, the popular minimally invasive procedures include laser treatment, varicose vein planing, holmium laser for varicose veins, and electrocoagulation for varicose veins in the lower extremities. So, in the early stage of the disease or after surgical treatment, how should the patients themselves perform self-care to relieve the symptoms and slow down the progress of the disease? Patients can take the following measures: appropriate exercise, avoid prolonged standing, walking and weight-bearing; wear medical elastic stockings when going out to work and activities; elevate the lower limbs when resting; the water should not be too hot when bathing the legs and avoid taking sauna; after sitting still for more than one hour, appropriate exercises such as tiptoeing should be performed to promote blood flow back to the lower limbs; drink more water appropriately to avoid blood concentration. The affected limb should still be protected after surgical treatment and avoid standing or sitting for a long time. If you get varicose veins in the lower limbs, you should go to the hospital for treatment in time, the longer you delay, the more difficult it will be to treat. In recent years, the prevalence of varicose veins in lower limbs is increasing year by year, and more and more people are showing symptoms of varicose veins in lower limbs, so they need to pay attention to it and get professional treatment in time.
