Thrombosis
Thrombosis is the formation of a blood clot (thrombus) within a blood vessel. This clot can partially or completely block blood flow, leading to serious complications like deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, or heart attack.
It is sometimes also known as Blood clot, thrombus, venous or arterial clot
