Question: Question about valves in blood vessels being destroyed

 AlamoCity - Wed Mar 07, 2007 8:26 pm

Can untreated superficial thrombophlebitis destroy the valves in blood vessels, or is that something that can only be done by DVT's?

Also, do the blood vessels in thighs have valves in them?

Thanks in advance

User avatar Dear Guest,

There are 2 types of blood vessels, veins and arteries.

Superficial thrombophlebitis is a condition that affects superficial system of veins.

Veins contain valves that make the flow of blood towards the heart and prevent its "backward" movement away from the heart.

If the superifical vein is affected by inflammation or thrombus formation (two different disease processes), and if inflammation or thrombus formation happens to involve the area where a valve is present, most probably this valve will be affected and will be destroyed leading to regurgitation of blood and its stagnation in the veins, leading to dilatation of the veins, a condition known as varicose veins.

Yes, the veins in the thigh contain valves.

Thank you very much for using our website and I hope that this information helped.

Yasser Mokhtar, M.D.
