Karotisstenos

Senast uppdaterad: Senast reviderad:
Sakkunnig:
Definition:
Förträngning i arteria carotis till följd av ateroskleros.
Förekomst:
Asymtomatisk karotisstenos blir vanligare med stigande ålder. Karotisstenos är orsak till 15–20 % av alla ischemiska hjärninfarkter. 
Symtom:
Tillståndet ger i sig inga symtom man kan leda till stroke/TIA.
Kliniska fynd:
Stenosljud kan förekomma. Eventuellt andra tecken på aterosklerotisk sjukdom.
Diagnostik:
Ultraljud kan påvisa karotisstenos med god säkerhet. Angiografi med DT eller MRT kan göras i vissa fall.
Behandling:
Vid asymtomatisk karotisstenos rekommenderas passande förändringar av levnadsvanor, trombocythämmande behandling och ofta statiner/blodtrycksbehandling. Vid symtomgivande karotisstenos med stenos ≥50–99 % kirurgi inom 14 dagar.
