thrombus thrombose - Health Topics
A thrombus occurs when the hemostatic process, which normally occurs in response to injury, becomes activated in an uninjured or slightly injured vessel. A thrombus in a large blood vessel will decrease blood flow through that vessel (termed a mural thrombus). What is thrombosis?
Understanding the Context
Thrombosis is the formation of a blood clot (thrombus) inside one of your blood vessels or a chamber of your heart. Clots can block blood flow in your blood vessels or break free and travel elsewhere in your body. A thrombus is a blood clot that occurs inside the vascular system. Blood clots help wounds heal, but a thrombus can cause dangerous blockages.

Key Insights
Thrombosis refers to the formation of a blood clot (thrombus) inside a blood vessel. These clots can partially or completely block blood flow, leading to serious health consequences like tissue death, organ damage, and functional impairment. A blood clot, or thrombus, is made mainly of platelets, fibrin, red blood cells, and white blood cells. The clotting process starts with platelet activation and the creation of a fibrin network. Thrombosis occurs when one or more blood clots develop in a blood vessel or the heart.
