چکیده
Se trata de una paciente de 69 años de edad, que fue encontrada en su domicilio con bajo nivel de consciencia, estridor espiratorio y midriasis derecha arreactiva, en el contexto de una crisis hipertensiva. La paciente fue intubada en su domicilio. n urgencias se practicó TAC craneal, que fue informado como normal. Ingresó en la UCI, donde se practicó nueva TAC a las 4 h, observándose un infarto talámico bilateral, compatible con obstrucción de la arteria de Percherón (fig. 1). a arteria de Percherón es una variante anatómica que se origina en el primer segmento de la arteria cerebral posterior. Su clusión produce infartos talámicos paramediales bilaterales. Es uno de los pocos ejemplos donde una única arteria cerebral rriga estructuras a ambos lados de la línea media.

Ischemic Stroke of the Artery of Percheron with Normal Initial MRI: A Case Report
The artery of Percheron is a solitary trunk representing an uncommon anatomic variant that provides bilateral arterial supply to the paramedian thalami and the rostral midbrain. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. The clinical diagnosis is difficult because the complex anatomy causes large clinical variability. We report a case of a comatose pat...
متن کاملBilateral thalamic stroke due to occlusion of the artery of Percheron in a patient with patent foramen ovale: a case report
INTRODUCTION Bilateral thalamic infarcts are rare presentations of stroke. They are the result of a complex combination of risk factors and a predisposing vessel distribution. The artery of Percheron, characterized by a single arterial trunk that irrigates both paramedian thalamic regions, can be occluded as a result of embolic diseases leading to bilateral paramedian thalamic infarcts. Clinica...
متن کاملBilateral thalamic infarcts due to occlusion of the Artery of Percheron and discussion of the differential diagnosis of bilateral thalamic lesions.
The Artery of Percheron is a rare vascular variant in which a single dominant thalamoperforating artery arises from one P1 segment and bifurcates to supply both paramedian thalami. Occlusion of this uncommon vessel results in a characteristic pattern of bilateral paramedian thalamic infarcts with or without mesencephalic infarctions. We report a case of a 31-year-old man with acute bilateral th...
متن کاملComplex neurological symptoms in bilateral thalamic stroke due to Percheron artery occlusion
The artery of Percheron is a rare anatomical variant where a single thalamic perforating artery arises from the proximal posterior cerebral artery (P1 segment) between the basilar artery and the posterior communicating artery and supplies the rostral mesencephalon and both paramedian territories of the thalami. Almost one-third of human brains present this variant. Occlusion of the artery of Pe...

متن کاملArtery of Percheron infarction: a case report
BACKGROUND The artery of Percheron is a rare anatomic variant of arterial supply to the paramedian thalamus and rostral midbrain, and occlusion of the artery of Percheron results in bilateral paramedian thalamic infarcts with or without midbrain involvement. Acute artery of Percheron infarcts represent 0.1 to 2% of total ischemic stroke. However, of thalamic strokes, occlusion of artery of Perc...
