Varicose Veins Treatment In India ...
What are VARICOSE VEINS?
The veins are the means by which blood is returned from the legs to the heart. Muscles in the foot, calf and thigh act as pumps to push blood from the foot to the heart and from the superficial veins (long saphenous and short saphenous veins) to the deep veins via perforator veins.
When muscles relax, blood is prevented from running back to the feet and from the deep to the superficial veins, by valves in the veins, which close like gates, once blood tries to run in the wrong direction.
Varicose veins occur when these valves or gates no longer work properly, allowing blood to bank up in the veins. The varicose veins you see in your legs are due to blood damming up in superficial veins and their branches. Why these veins fail is not completely understood. It may be due to a weakness in the valve itself or in the vein wall
Types of varicose veins
1. Thread or Spider Veins: These occur mainly in women, and are more common in the thigh. There may be no other varicose veins.
2. Primary Varicose Veins: These are the most common type and occur in the long and short saphenous veins and their branches.
3. Secondary Varicose Veins: These act as bypass veins when the deep veins have been damaged or occluded. They should not be removed.
4. Vulval Varices: They occur in women as a complication of pregnancy or infection and are due to reversal of flow in the internal iliac vein.
