Thrombosis

Definition

Thrombosis is the formation of a blood clot within a blood vessel, obstructing the flow of blood through the circulatory system. It can lead to serious conditions if not treated promptly.

5 Must Know Facts For Your Next Test

1. Thrombosis can be caused by bacterial infections that invade the bloodstream, leading to immune responses that promote clot formation.
2. Common sites for thrombosis include deep veins in the legs (deep vein thrombosis) and arteries supplying the heart (coronary thrombosis).
3. Complications from thrombosis can include embolism, where a part of the clot breaks away and travels through the bloodstream, potentially causing blockages in critical areas like the lungs (pulmonary embolism).
4. Staphylococcus aureus and Streptococcus pyogenes are examples of bacteria that can cause infections leading to thrombosis.
5. Inflammation from bacterial infections can damage endothelial cells lining blood vessels, making them more prone to clot formation.
