Varicose veins refer to tortuous and dilated veins caused by blood stasis and weak vein walls.
Varicose can occur in veins in many parts of the body. For example, hemorrhoids are actually a kind of varicose veins. Clinically, there are also esophageal and gastric varices, varicocele and abdominal wall varicose veins. The most common site of varicose veins is in the lower extremities.
It is worth emphasizing that varicose veins itself may be a secondary manifestation of other diseases, such as vena cava occlusion, and the primary disease should be actively treated.
There are many causes of varicose veins of the lower extremities, the most common is simple superficial varicose veins of the lower extremities, the main cause is the insufficiency of the femoral saphenous vein valve.
Another important cause is found in primary deep venous valvular insufficiency (PDVI), because it is often associated with great saphenous venous valvular insufficiency, and often shows tortuous expansion of superficial veins.
In addition, post-deep vein thrombosis syndrome of the lower extremities, due to poor deep venous return, compensatory tortuous expansion of the superficial veins; lower extremity arteriovenous fistulas, venous malformations and bone hypertrophy syndrome may also have lower extremity varicose veins; inferior cavities Obstruction of venous return, such as Budd-Chiari syndrome, can also lead to varicose veins in the lower extremities.
The main symptoms
1. The superficial blood vessels are varicose like earthworms, obviously protruding from the skin, and the varicose is in the form of lumps or nodules;
2. Soreness in the legs, pigmentation, desquamation, itching of the skin, edema of the ankles;
3. Abnormal feelings in the limbs, acupuncture, itching, numbness, burning sensation;
4. The skin temperature rises, there is pain and tenderness;
5. Local gangrene and ulcers.
In the case of simple superficial varicose veins of the lower extremities, the general clinical symptoms are mild and the progress is slower, and most of them are simple varicose. In a few cases, thrombophlebitis, venous ulcers, etc. may occur;
In the case of deep venous valve insufficiency, or even obstruction of deep venous return, the condition is relatively serious. When standing on the calf, there is a feeling of heaviness, fatigue, and even swelling and rupture of the lower limbs. In the later stage, skin nutritional changes and prolapse will occur. The formation of dandruff, atrophy, pigmentation, and eczema ulcers.
How to treat
Varicose veins of the lower extremities can be treated by wearing elastic stockings, injecting sclerosing agents, and surgical removal. Deep vein valve insufficiency can be used for valve repair surgery and laparoscopic communication branch ligation.
Varicose veins in the lower extremities may also indicate the existence of other diseases, and the primary disease needs to be actively treated; if the deep veins are not smooth, the surgical treatment of the superficial veins should be more cautious.
1. Obese people should lose weight. Although obesity is not the direct cause, the pressure of excessive weight on the legs may cause poor venous return in the legs and increase the expansion of the veins.
2. People who have been engaged in heavy physical labor and standing work for a long time should wear elastic stockings to keep the superficial veins under pressure.
3. Women should take special care of their legs during special periods such as menstruation and pregnancy, rest more, and massage their legs frequently to help blood circulation and avoid varicose veins.
