Varicose veins (commonly known as "hamstring muscle") are the most common diseases of venous system. The main reason for the formation is that blood accumulates in the lower limbs because of keeping the same posture for a long time, and the venous valve is destroyed over time, resulting in increased venous pressure and varicose veins. Varicose veins mostly occur in the lower limbs, and the skin of the legs is red or blue, like cobwebs, twisted blood vessels of earthworms, or hard nodules like tree tumors. The veins are abnormally enlarged, swollen and varicose. According to statistics, about 25 ~ 40% of women and 20% of men in Taiwan Province Province suffer from varicose veins. Teachers, surgeons, nurses, hairdressers, counter girls, chefs, restaurant waiters and other occupations that need to stand for a long time are all high-risk groups. In addition, varicose veins are related to heredity, oral contraceptives and pregnancy. Varicose veins are an irreversible phenomenon because the human body has no mechanism of self-repairing membrane, but we can still prevent varicose veins from expanding and alleviate their symptoms through conservative treatment (such as using elastic socks, exercising, changing diet and life schedule). Walking, swimming and cycling can not only improve circulation, but also reduce the incidence of new varicose veins. In terms of diet, we should eat more high-fiber and low-fat diets and strengthen vitamin C and E supplements. In daily life, we should control our weight, avoid taking birth control pills, avoid wearing tight clothes and high heels, cross our legs and avoid sitting or standing for a long time. Raise your legs for a period of time before going to bed every day and sleep on your left side to relieve pelvic venous pressure. Smoking can raise blood pressure and damage arteries and veins. Patients with varicose veins should quit smoking immediately.

Most patients with varicose veins are not serious and do not need treatment. Health care and prevention are the most important. But if varicose veins are too serious, it is easy to produce recurrent ulcers, infections and bleeding. Mistaking folk remedies and using the wrong treatment will aggravate the symptoms of varicose veins. Therefore, the best way is to consult a specialist and give appropriate advice. Treatment of varicose veins includes the following:

Compression therapy: use elastic socks, and use external pressure to reduce edema during exercise. Theoretically speaking, the pressure of elastic socks is the largest at the ankle and gradually decreases upward. It is usually best to wear elastic socks that can reach your thighs. It is best to wear elastic socks before getting up in the morning and then take them off after going to bed at night. If patients have leg ulcers due to venous hypertension, they should respect the doctor's advice, take antibiotics and diuretics, supplemented by special hygiene materials.

Sclerosing agent treatment: Inject hypertonic solution (such as high-concentration saline or sclerosing agent) into varicose veins to destroy the intima of blood vessels and make it disappear after sealing. However, it can only treat varicose veins, and severe pain, pigmentation, even inflammation, redness, ulceration and other sequelae may occur during the treatment, and it is easy to recur, and it is difficult to treat after recurrence, which is only suitable for a few patients.

Extravascular laser or pulsed light: Like the principle of laser beauty spot removal, it has the advantages of only local anesthesia, short treatment time, low pain, relatively small wound, no ugly scar and immediate walking. But it is only effective for micro-spider varicose veins, and several courses of treatment are paid at one's own expense.

Surgical removal: incision is made in the groin to cut off and ligate or remove the great saphenous vein, which requires hemianesthesia or general anesthesia and hospitalization for 2-3 days. If the varicose veins are too serious, it may take several small wounds to remove the varicose veins one by one. The treatment is complete, but there are some shortcomings, such as subcutaneous bruising and painful wounds.

Intravascular cauterization: Make a small incision on the inside of the knee or ankle, put a very thin catheter, cauterize and block the varicose venous blood flow with high-frequency wave (or radio frequency) or laser beam. Simple intravascular cautery has the advantages of being performed under local anesthesia, no hospitalization, less scar and pain, walking home after elastic tension treatment and high success rate. However, health insurance is not paid at one's own expense, and most patients may not only solve it by this method alone, but also need other methods such as minimally invasive varicocele surgery system to have a more complete treatment.

Minimally invasive varicose vein rotating endoscopic system: the earthworm-like vein is sucked out through endoscope and suction rotation. The wound is smaller and more beautiful than traditional surgery, but it needs anesthesia and hospitalization, and consumables need to be paid at their own expense.
