ICD-Code I82.1: Thrombophlebitis migrans

The veins below your skin are blocked by blood clots and inflamed.

Over time, this condition can affect veins in different parts of the body. This is also known as migratory inflammation of the veins.

Veins are blood vessels that transport blood back towards the heart. There is a distinction between deep veins and veins beneath the skin. The veins beneath the skin gather the blood from the skin and carry some of the blood to the deeper veins. The deep veins collect the blood from the organs and muscles. The deep veins then carry the blood towards the heart.

Blood clots occur when various components of the blood clump together. A blood clot can block a blood vessel. If 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. The affected area may be painful or take on a bluish color. When veins are inflamed, they may turn red and harden. The affected area may feel hot and be painful. You may also have a slightly elevated temperature.

There are various causes of blood clots in the veins and inflammation of the veins. In some cases, the cause is another health condition. These include disorders of the blood vessels or infections, for example. In some cases, a precise cause is not found.
