Artery of Percheron Infarction: A Short Review

Asim Kichloo et al. J Investig Med High Impact Case Rep. 2019 Jan-Dec.

Abstract

One uncommon type of ischemic stroke is occlusion of the artery of Percheron (AOP) leading to infarction of the paramedian thalami and mesencephalon. There are several variants of thalamic blood supply, and identifying the potential presence and infarction of an AOP is important in diagnosis and treatment of ischemic strokes affecting the thalami and mesencephalon, especially because of the unusual and variable presentation of these forms of ischemic strokes. This short review includes and discusses the case of a 58-year-old woman with an AOP infarct and indicates the importance of recognizing an AOP infarct early despite its clinical variations in order to treat the stroke in a timely fashion. This short review also includes a discussion of imaging modalities in such cases and clinical differential diagnoses to consider with management strategies.

Keywords: artery of Percheron; infarct; thalamic infarction.
