Bypassoperasjon på hjertet

En bypassoperasjon er et inngrep hvor man åpner brystkassen og syr inn en eller flere årer, som tas fra et annet sted på kroppen, slik at blodet kan ledes forbi de trange partiene i koronararteriene.

En by-pass operasjon er et stort inngrep som foregår i narkose og tilkoplet såkalt hjerte-lungemaskin.

Trange koronararterier?

Hjertet er en kraftig muskel som pumper blodet rundt i kroppen. For å klare pumpejobben trenger hjertet hele tiden tilførsel av oksygen (surstoff) og andre næringsstoffer. Denne tilførselen kommer fra blodet via blodårer som ligger utenpå hjertet, koronararteriene (kransårene). Det er tre større koronararterier. De forsyner ulike områder av hjertet med blod. Hver koronararterie deler seg opp i stadig mindre årer slik at hele hjertemuskelen får god tilførsel av oksygen og næring.
