In daily life, we will know about varicose veins, and many patients of varicose veins think like this: “My varicose veins have been many years, no pain, no itch, no big problem, no need to treat.” However, there are also some patients who cry out as soon as they come to the specialized peripheral vascular department clinic of the First Affiliated Hospital of Henan College of Traditional Chinese Medicine: “My varicose veins were said to be operated by the doctor many years ago, but I put it off again and again and got this way, so I really regret it!” Zhou Tao, peripheral vascular department of the First Affiliated Hospital of Henan College of Traditional Chinese Medicine Is varicose veins really a minor problem? These patients from “no pain” to “regret”, in the end what happened? In fact, varicose veins are generally asymptomatic in the early stage except for the appearance of prominent bruises. But after several years, as the disease progresses, its harm will gradually appear, mainly manifested as follows: (a) edema Because of the reflux of veins, patients often present morning light and evening heavy edema of affected limbs. (ii) Skin pigmentation Long-term venous hypertension leads to increased capillary permeability in the lower leg, rupture of erythrocytes after exudation, and deposition of ferritin under the skin, causing the skin to darken, developing from spots to patches. (iii) Bleeding The skin in the area through which the varicose veins pass is very fragile due to insufficient nutrition. In case of carelessness, it can easily lead to rupture of the varicose vein which can cause hemorrhage. The bleeding is often unnoticed by the patient because it is not accompanied by other symptoms such as pain, which can lead to serious consequences if it occurs at night while sleeping. (iv) Ulcers The most common consequence of varicose veins is the occurrence of ulcers due to nutritional changes in the skin, which can be long lasting and have a localized foul odor and pus, seriously affecting daily life. (v) Venous thrombosis Some patients can form thrombosis in the superficial veins of varicose veins, which is characterized by local redness, swelling and pain, and hard lump formation, affecting walking; if left untreated, the thrombosis may spread to the deep veins through the traffic veins, resulting in deep vein thrombosis, with the risk of life-threatening pulmonary embolism. In addition, we need to emphasize that: from the medical point of view, varicose vein is not a simple disease, but only a clinical manifestation, many diseases such as lower limb deep vein malformation, arteriovenous fistula, deep vein thrombosis sequelae, congenital venous valvelessness, inferior vena cava syndrome, Buga’s syndrome, etc. can have the manifestation of lower limb varicose vein, if the cause is not clear, misdiagnosis and mistreatment, it may cause serious consequences to If the cause of varicose veins is not clearly identified, misdiagnosis and mistreatment may cause serious consequences to the patient. This shows that varicose veins are not simple, early diagnosis and early and correct treatment are the key!
