Changsha Evening News, December 7 (Quan** reporter Xu Yuan, correspondent Yi Ting) 62-year-old Mr. Liu has endured the pain of varicose veins in his lower limbs for more than 30 years. "When you squat, you feel a pulling pain, and it hurts to stand or walk for a long time. Recently, the pigmentation on Mr. Liu's left leg spread from the calf up to the thigh, and the surface looked like it was crawling with "earthworms", and the slightest touch would cause pain. In the general surgery clinic of Hunan Women and Children's Hospital, Mr. Liu was diagnosed with severe varicose veins of the lower limbs, and the condition could not be alleviated by conservative **, and only through surgery could he **.
Varicose veins have become a common chronic vascular disease in modern society, but many patients tend to ignore it in the early stage. Liu Fan, deputy chief physician of the Department of General Surgery of Hunan Women and Children's Hospital, said that varicose veins of the lower limbs are mainly caused by standing or sitting for a long time, or congenital venous wall fragility and imperfect venous valve function, resulting in unsmooth blood in the vein, and increased intravenous pressure, which in turn causes the distortion and expansion of the vein. In severe cases, the slightest touch can cause pain and even ulceration. If not carried out in time**, long-term poor blood circulation may lead to complications such as hyperpigmentation, venous ulcers and superficial thrombophlebitis of the lower limbs, and in severe cases, deep vein thrombosis may occur, and once the embolus falls off, pulmonary embolism may occur, which is life-threatening.
Surgery is not the only method, for non-severe varicose veins, conservative methods can be used, including elevation of the affected limb, wearing compression stockings, etc., and obese patients need to lose weight and exercise regularly. Liu Fan introduced that in medicine, varicose veins are divided into 6 grades according to the severity of them, and different grades of varicose veins are different, and patients can conduct self-examination.
Grade 1 very early: superficial varicose veins may be seen, but telangiectasias are usually sufficient, compression stockings or sclerosings** are sufficient.
Grade 2 early stage: significant superficial varicose veins may be seen, and the patient should undergo minimally invasive surgery such as laser**, supplemented by sclerosing**, which is the most timely**.
Grade 3 intermediate: significant superficial varicose veins with lower extremity edema may be seen, and laser plus other minimally invasive procedures can still be performed**.
Grade 4 intermediate to late: with significant pigmentation and itching, eczema, requiring minimally invasive or other surgical modalities, supplemented by laser**.
Grade 5 and 6 advanced stage: ulcers appear, at which point comprehensive surgery or even deep vein intervention is required**.
To prevent varicose veins of the lower limbs, we should pay attention to avoid standing for a long time in daily life to reduce the accumulation of venous bloodAvoid sitting for a long time, people who need to sit for a long time should have their legs parallel to each other, avoid stilted legs, and get up and move every 1 hour;Proper daily exercise, such as swimming, cycling, yoga, etc., can strengthen the calf muscles and promote blood circulation in the lower limbsMaintain a normal weight to avoid increased burden on the leg veins due to overweight and poor blood returnTry to wear loose and comfortable clothing, too tight pants, socks, etc. may affect the blood return of the lower limbs.
