IPA: /ˌɛmbəlaɪˈzeɪʃən/
KK: /ɛmboʊlɪˈzeɪʃən/
A medical procedure that involves blocking a blood vessel to stop bleeding or to cut off blood supply to a tumor or abnormal growth.
The doctor recommended embolisation to treat the patient's vascular condition.
Embolisation is formed from "em-" (meaning in or into) and "bolus" (from Greek "ballein", meaning to throw). The term describes the process of throwing or placing something into a vessel, particularly in a medical context where it refers to the intentional obstruction of a blood vessel.
Think of 'throwing something into' ('em-') a vessel ('bolus') to remember that embolisation means placing something into a blood vessel to block it.
