The venous pressure of lower limbs in normal people gradually increases from top to bottom. The ideal varicose socks should be able to produce gradually decreasing pressure on the lower limbs from bottom to top, support the veins of the lower limbs, promote the venous blood return of the lower limbs, effectively relieve or improve the pressure of the veins and venous valves of the lower limbs, and obviously improve the clinical symptoms of venous insufficiency. So how to choose varicose socks for lower limbs?

When choosing the right size and pressure to use varicose socks, we must first master the strength and length of varicose socks, and accurate size measurement is the premise of using varicose socks. Varicose socks can be divided into low-pressure prevention type (2.4 kPa), first-class medium-pressure treatment type (2.7~4.0 kPa), second-class high-pressure treatment type (4.0~5.3 kPa) and third-class high-pressure treatment type (5.3 ~6.6 kPa) according to the pressure. Low-pressure preventive type is often used for daily health care and prevention of bedridden patients and people with high incidence of varicose veins and thrombosis; Primary medium pressure therapy is suitable for the treatment and prevention of varicose superficial veins and thrombosis. After stripping great and small saphenous veins, sclerotherapy of varicose veins, deep venous thrombosis syndrome of lower limbs, severe varicose veins of lower limbs, etc., two or three levels of high pressure therapy were used.

Leg varicose socks have two basic lengths: socks should be 3.3 cm below the knee and stockings should be 3.3 cm below the groin. Socks should be easy to adjust and comfortable as needed, but for patients with great saphenous vein peeling and very fat patients with thigh circumference greater than 65 cm, stockings should be used. When socks are worn to the knees, the circumference of two places should be measured, the narrowest part of the ankle-about 2.5 cm above the ankle bone and the thickest part of the fibula, and then the distance from below the knee to above the heel should be measured; Use stockings to the thigh, and take the same steps to measure the distance from the thickest part of the thigh and above the heel to the hip. If the patient's condition or leg type changes, it needs to be measured again to ensure the comfortable fit of varicose socks. For example, patients with edema need to measure at least 1 time /d to see if they need larger varicose socks. Generally, the leg diameter should be increased by 5 cm, and the pressure of varicose socks should be increased by 2 times. When choosing varicose socks, you need to know the contraindications of medical varicose socks. Contraindications of medical varicose socks mainly include: patients with arterial insufficiency in the third stage are absolutely forbidden to use varicose socks, because excessive pressure will block arterial blood supply, and because varicose socks oppress superficial blood vessels of subcutaneous tissue, which has serious harm to ischemic lower limbs, so patients with severe vascular diseases and obese patients with leg edema are forbidden to use them. Patients with leg and foot infection and subcutaneous tissue inflammation, abscess, furuncle, erysipelas and other acute stages can cause severe pain under pressure, and skin diseases such as eczema, fungal infection and venous ulcer should be completely cured before use.

1, choose varicose socks with appropriate pressure according to the symptoms of the wearer's legs:

Varicose socks are divided into the following pressure grades

Primary low-pressure prevention and health care type (15-25mmhg): it is suitable for health care and prevention of people with high incidence of varicose veins and thrombosis;

First-class medium-pressure therapy (25-30 mmHg): suitable for patients with early varicose veins;

Moderate treatment of secondary hypertension (30-40 mmHg): It is suitable for patients with obvious varicose veins of lower limbs (veins protruding from the skin surface when standing) accompanied by leg discomfort (such as soreness of lower limbs, eczema and itching, cramps and numbness, pigmentation, etc.). ), phlebitis, severe varicose veins during pregnancy, postoperative varicose veins (stripping of great and small saphenous veins), patients with deep vein thrombosis syndrome;

Severe treatment type of tertiary hypertension (40-50mmhg): suitable for patients with high swelling of lower limbs, ulcer, blackening and hardening of skin, high lymphedema, recovery period after plastic liposuction, etc.

2. Choose the length of varicose socks according to the lesion:

Socks (below the knee), stockings (and thighs), pantyhose (and waist)

If the wearer only suffers from varicose veins below the knee, he can wear medium varicose socks; If the wearer has symptoms above the knee, he needs to wear long or pantyhose varicose socks.

3, determine the appropriate size

(Varicose socks are divided into small S, medium M, large L and extra large XL)

Measure the three main dimensions (centimeters) of the wearer's leg: the circumference of the ankle (the thinnest part of the ankle), the maximum circumference of the calf and the maximum circumference of the thigh to determine the appropriate number. When buying pantyhose, choose the number according to the height and weight of the wearer.
