Saphenous varicose veins are a common disease in life and are a type of varicose veins. The cause of saphenous varicose veins is genetic. Prolonged standing work, especially heavy physical work, is a trigger for the disease. The pathogenesis of saphenous varicose vein is the aneurysmal expansion of the saphenous vein valve, which causes the valve at the confluence of the superficial and deep veins of the lower limbs to lose its role as a “one-way valve”, resulting in impaired blood return to the lower limbs, backflow of blood from the veins, stasis of blood in the saphenous veins, and tortuous and dilated veins. In the early stage of saphenous varicose vein, the superficial veins of the lower limbs become worm-like bruised and dilated, which causes discomfort and pain when the patient stands and disappears when walking or lying down. When the disease progresses to the later stage, the skin of the lower extremities becomes nutritionally impaired due to poor blood circulation, and skin atrophy, desquamation, itching, pigmentation, skin and subcutaneous tissue sclerosis, and even eczema and ulcer formation occur. Especially in the back of the foot, ankle and lower leg, the skin is ulcerated after serious or traumatic injury and does not heal for a long time, which is commonly called “old rotten foot”. Symptoms of saphenous varicose vein The early symptoms are: after standing for a long time, the legs are sore and swollen, easily fatigued and weak; generally speaking, the symptoms are lighter in the morning when you wake up, and the symptoms are aggravated at night after a busy day at work; some patients have numbness and mild pain in the inner side of the ankle; there is a worm-like blue varicose vein mass in both calves. The later symptoms are: both legs are very sore and swollen after standing for a long time, even affecting work; both calves are covered with varicose vein masses; eczema and ulcers of the feet and ankles appear, and ulcers of the feet and ankles appear due to the development of varicose veins to the middle and late stages. The first treatment of saphenous varicose vein is surgery, which is suitable for patients with light and limited varicose veins and no serious complications and good deep vein patency; the second sclerotherapy, which is also suitable for varicose veins with light and limited and good deep vein patency and no serious complications, but both surgery and sclerotherapy are a destructive treatment; the third is “thrombolysis of veins “This therapy mainly adopts oral pure Chinese medicine to treat saphenous varicose veins, using meridian-unblocking drugs to change the elasticity of the inner wall of blood vessels and quickly repair the damaged valves, so that the protruding masses and striated vascular masses gradually shrink and smooth. By adjusting the function of the body, the factors of thrombosis are eliminated and new thrombosis is prevented, so that the blood vessels of the affected limbs can carry out normal metabolism and thus the disease is eliminated.
