I80.1: Phlebitis and thrombophlebitis of femoral vein

The veins carry the blood to the heart from the body. The veins in your thigh are inflamed or they have been blocked by blood clots.

If the veins get blocked by blood clots, the blood is unable to flow properly. Then, as a result of the blocked veins, the skin can turn red and swell up. There are various reasons for blood clots forming. If someone is unable to move their legs properly, or if the vascular wall has been injured, a blood clot can form more quickly. Some people are prone to blood clots. This is then congenital or caused by another disorder. Inflammations in the veins can also favor the formation of blood clots.

Veins can become inflamed for different reasons. Some medications are put straight into the veins. Some of these medications can cause a vein inflammation. The veins can also be inflamed by pathogens.
