CASE REPORTS
JOURNAL ARTICLE
Artery of Percheron Stroke.
Journal of Emergency Medicine 2018 July
BACKGROUND: Coma is not a common symptom of stroke.
CASE REPORT: We present a patient with a stroke to the artery of Percheron, which infarcted the bilateral paramedian thalami and resulted in coma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Identifying strokes in comatose patients is important for therapeutic management. The bilateral thalami are involved in maintaining consciousness. The artery of Percheron is an anatomic variant in the posterior circulation whereby the bilateral paramedian thalami are perfused by it solely. This is an atypical stroke syndrome that emergency physicians need to be able to identify.
