How do varicose veins form?

Many people have experienced symptoms of varicose veins. In fact, varicose veins have many clinical manifestations. We must prevent the occurrence of varicose veins. There are many reasons that lead to varicose veins. As long as we understand what varicose veins are and the clinical manifestations of varicose veins, we can actively prevent and treat varicose veins.

So how are varicose veins formed? What are the factors that cause varicose veins? What are the symptoms of varicose veins? Below we will introduce in detail how varicose veins are formed.

Varicose veins refer to the tortuosity and dilation of veins due to factors such as blood stasis and weak venous walls. Varicose veins can occur in many parts of the body. For example, hemorrhoids are actually a type of varicose veins. Other clinically visible varicose veins include esophageal varicose veins, varicocele, abdominal wall varicose veins, etc. The most common site of varicose veins is the lower extremities. It is worth emphasizing that varicose veins themselves may be a secondary manifestation of other lesions, such as vena cava occlusion, and the primary disease should be actively treated.

There are many causes of varicose veins in the lower limbs, the most common of which is simple superficial varicose veins in the lower limbs, the main cause of which is the insufficiency of the femoral saphenous vein valve. Another important cause is primary deep venous insufficiency (PDVI) of the lower extremities, which is often combined with great saphenous vein valvular insufficiency and often manifests as tortuous dilatation of the superficial veins. In addition, post-deep vein thrombosis syndrome in the lower limbs causes compensatory tortuous dilatation of the superficial veins due to poor deep vein reflux; lower limb arteriovenous fistula and venous malformation hypertrophy syndrome can also present with varicose veins of the lower limbs; obstruction of the inferior vena cava reflux, such as Budd-Chiari syndrome, can also lead to varicose veins of the lower limbs.

Varicose vein symptoms

1. The surface blood vessels are varicose like earthworms, obviously protruding from the skin, and the varicose blood vessels are in the shape of masses or nodules;

2. There is a feeling of soreness and swelling in the legs, pigmentation, desquamation, itching on the skin, and edema in the feet and ankles;

3. Strange sensations in the limbs, such as tingling, itching, numbness, or burning;

4. The epidermal temperature rises, with pain and tenderness;

5. Local gangrene and ulcers.

If it is simple varicose veins of the lower limbs, the clinical symptoms are generally mild and progress slowly, mostly manifested as simple varicose veins. In a few cases, there may be thrombophlebitis, venous ulcers, etc.; if it is deep vein valve insufficiency or even deep vein reflux obstruction, the condition is relatively serious, with a feeling of heaviness when standing in the calf, easy fatigue, and even swelling and bursting pain in the lower limbs. In the later stage, nutritional changes in the skin occur, desquamation, atrophy, pigmentation, and the formation of eczema ulcers.

Above we introduced what varicose veins are. We know that varicose veins pose a threat to patients' health, so we must actively prevent and treat varicose veins. The above article introduces in detail the clinical manifestations of varicose veins and how varicose veins are formed. I believe the above introduction will be helpful to everyone.
