GALEANO, Martha; ARANDA, Gonzalo; OBELAR, Noelia  and  MULLER, Gerardo. Percheron’s artery oclussion: An atypical stroke syndrome. An. Fac. Cienc. Méd. (Asunción) [online]. 2022, vol.55, n.3, pp.122-125. ISSN 1816-8949.

The thalamus has a complex vascular supply, full of anatomical variants of relevance to medical students. The presence of the Percheron artery is one of these anatomical variants, and the infarction produced by its occlusion is characterized by a rare clinical picture, little known by doctors in the Emergency Department. It is generally associated with the triad of impaired consciousness, vertical gaze palsy, and memory disturbance. We present the case of a 54-year-old man who presented with altered sensorium, drowsiness and memory alterations, in whom adequate therapy could not be carried out due to ignorance of this entity.
