IPA: /ˌɛmbəˈlɛk.tə.mi/
KK: /ɛmˈboʊlɛkˌtomi/
A medical procedure that involves the surgical removal of an obstruction, known as an embolus, from a blood vessel.
The doctor performed an embolectomy to clear the blocked artery.
Embolectomy is formed from "embolus" (from Greek "embolos", meaning a plug or stopper) and "-ectomy" (from Greek "ektome", meaning excision or removal). The word refers to the surgical removal of an embolus, which is a blockage in a blood vessel.
Think of a 'plug' ('embolus') being 'removed' ('-ectomy') from a blood vessel — that's what embolectomy means.
