Blodpropp i graviditeten: Årsak

Innhold i artikkelen

Blodkarskade, infeksjon og vevsskade kombinert med økt blodlevringstendens og forstyrrelse av blodstrømmen, setter i gang prosessen som ender med dyp venetrombose. I svangerskapet vil den gravide livmoren kunne trykke på blodårene i buken og medføre nedsatt blodstrøm. I tillegg fører hormonforandringene til at blodet levrer seg lettere hos gravide enn hos kvinner utenom graviditet.

Annonse

Embolier kan oppstå hvis biter av en blodpropp løsner, følger blodstrømmen og fester seg i en mindre blodåre.

Risiko for blodpropp i svangerskapet øker med alder (> 35 år), fedme (KMI > 30), antall tidligere barn og familiær forekomst av blodproppsykdom. Svangerskapet er i seg selv en risikofaktor for utvikling av blodpropp. Tilleggsfaktorer som øker faren, er røyking, keisersnitt, sengeleie og overvekt/fedme. Arvelige forstyrrelser i blodlevringssystemet (trombofilier) gir markant økning i risikoen for blodpropp.
