A condition where a blood vessel is blocked by a blood clot that has moved from its original place.
The doctor diagnosed her with thromboembolism after she experienced sudden chest pain.
Thromboembolism → It is formed from "thrombus" (from Greek "thrombos", meaning clot) and "embolismos" (from Greek "embole", meaning a throwing in). The word describes a condition where a blood clot (thrombus) travels through the bloodstream and lodges in a vessel (embolism).
Think of a 'clot' ('thrombus') that is 'thrown in' ('embolismos') to a blood vessel, which helps you remember that thromboembolism refers to a clot that moves and causes blockage.
