Thromboembolism can be classified as arterial thromboembolism (ATE) and venous thromboembolism (VTE).
Arterial thromboembolism (ATE): include cerebrovascular accidents, myocardial infarction, transient ischaemic attacks, and other arterial thromboembolic events.
Venous thromboembolism (VTE): include deep vein thrombosis (DVT) and pulmonary embolism (PE).
Formation of a blood clot inside a blood vessel (thrombus) which then breaks free (embolism) and obstructs the blood flow in the circulatory system.
The onset of a VTE can be within days to weeks of commencing treatment.
