1. 1. The Ability of Circle of Willis Integrity toPredict Future Ischemic Stroke in theElderly Population

   University essay from Örebro universitet/Institutionen för medicinska vetenskaper

   Author : Victor Förström; [2022]
   Keywords : Circle of Willis; collaterals; stroke; CTA; cerebrovascular disease.;

   Abstract : Background The Circle of Willis (CoW) is an arterial anastomotic circle located at the skull base thatmaintains collateral circulation in the brain. Variations in CoW anatomy are commonly presentin the general population. Absent or hypoplastic segments of the CoW have been linked to anincreased stroke risk. READ MORE
