Varicose Veins


Symptoms of Varicose Veins And Thrombosis

Varicose veins are enlarged veins whose valves no longer meet properly. As a result, blood collects in the veins, leading to further vein enlargement and valve dysfunction. A common cause of valve failure is the increase in hydrostatic pressure and clotting of the blood (thrombosis).

The development of varicose veins usually occurs in the superficial venous system of the lower limbs, especially in the long saphenous veins (LSVs) and their tributaries.

Varicose veins can lead to thrombophlebitis (due to inflammation or blockage of the vein) and subsequent bleeding of the swollen veins near the skin surface. Other complications, such as Oedema, skin pigmentation, varicose eczema and venous ulceration, are mainly a result of venous hypertension.

Compression therapy can be used in the prevention of varicose veins by reducing the diameter of the veins so the valves are well supported and can function effectively. During treatment, compression garments can help increase the total volume of blood flow within the veins.
