How Does Venous Thromboembolism (VTE) Occur?
Venous Thromboembolism

An appropriate and healthy response to a little cut or wound is blood clotting. Your blood coagulates, or partially solidifies, to prevent it from oozing out of a hole too quickly. This results in a scab on your body's surface. It creates a clot inside of your body. A wound-like irritation of the blood vessel lining caused by an infection can also cause blood to clot. The clot is intended to disintegrate after the infection or wound starts to heal. Nevertheless, it doesn't always. And occasionally blood clots develop even when there is no cut. This may be caused by a variety of circumstances. The vein may become blocked if the clot is large enough.

The form of blood clot that commonly results in a heart attack or stroke is not a venous thromboembolism. They typically result from blood clots in your arteries rather than veins. Yet, a Venous Thromboembolism (VTE) can be just as harmful. The most severe side effects happen when a VTE escapes from its original site, travels through your bloodstream, and becomes lodged in the veins of your lungs. A pulmonary embolism is what this is (PE). A PE lowers blood and oxygen flow to your lungs while raising artery blood pressure. As a result, pulmonary hypertension develops, which can lead to fatal heart failure.
