All About Varicose Veins

By Dr. Sudhir Pudi Radiology

enlarged and twisted veins are known as varicose veins. Although it can happen anywhere, usually it refers to the present veins in the legs. Pairs of valves are present in veins that prevent blood flow back (venous reflux or retrograde flow). The blood in the veins is pumped to the heart against the effects of gravity using the leg muscles.

By becoming varicose, the leaflets in the valve do not meet properly, thus rendering useless valves (valve insufficiency). Because of this, the blood begins to flow back and results in enlargement.


Varicose occur primarily in the superficial veins of the leg. This is caused due to the legs being subject to physical activities such as standing, running, walking, etc. Apart from being an aesthetic, varicose problem can produce a lot of pain.
