Abstract:

El infarto bitalámico simultáneo es una presentación isquémica infrecuente. La arteria de Percheron, presente en un tercio de la población, vasculariza la región paramediana de ambos tálamos y mesencéfalo rostral. El diagnóstico es dificultoso, por lo que reconocer esta variante anatómica es importante, siendo su afectación la causa más frecuente de infartos bitalámicos. La resonancia nuclear magnética juega un papel fundamental en el diagnóstico. El tratamiento dependerá de la etiología subyacente. Se describen dos casos clínicos, con hipersomnia como síntoma común, en los que se llega al dia

Introdução. A artéria de Percheron é uma variante anatômica da irrigação do sistema nervoso central, sendo especificamente um tronco único que se origina na artéria cerebral posterior e irriga o território talâmico através de seus ramos em ambos os hemisférios. O infarto dessa artéria constitui-se como uma apresentação atípica de acidente vascular cerebral isquêmico, cujas principais manifestações clínicas estão relacionadas à hipóxia do tálamo, embora não haja um padrão.

El síndrome de Percherón o infarto talámico bilateral sincrónico es una entidad poco frecuente y de difícil diagnóstico clínico. La compleja estructura del tálamo en núcleos, así como su peculiar irrigación y la variabilidad anatómica individual hace que las lesiones isquémicas puedan presentarse de forma bilateral en ambos tálamos por la obstrucción de una única arteria, caracterizando este cuadro. Presentamos un caso con lesiones isquémicas agudas en ambos tálamos y mesencéfalo anterior, compatible con la obstrucción de la arteria de Percherón.

Early diagnosis of artery of Percheron infarction can be challenging because it is infrequent and early computed tomography or magnetic resonance imaging may be negative. Thus, it can be confused with other neurological conditions such as tumours and infections. Methods This is a retrospective case study of a gentleman admitted to

Abstract:

The artery of Percheron (AOP) is a relatively rare anatomic variant in which a solitary arterial trunk branches from the proximal segment of the posterior cerebral artery and provides arterial supply to the paramedian region of the thalami bilaterally and often to the rostral part of the midbrain. Occlusion of the artery of Percheron results in bilateral paramedian thalamic infarcts with and without midbrain involvement. Recognition of this condition as an acute stroke may be challenging due to various nonlocalized clinical presentations, given the wide range of neurological functions subserve

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.

AOP occlusion can lead to bilateral thalamic and rostral midbrain infarct presenting as memory loss, fluctuating levels of consciousness, and altered mental status. A 43-year-old woman with a history of antiphospholipid syndrome (APS), managed on dabigatran, presented with acute confusion and drowsiness. She had slurred and slowed speech, disorientation in time and place, left-sided facial droop, decreased power of the left side (4/5), and was unable to walk due to generalized weakness. Labs showed a prolo

Abstract:

Bilateral thalamus ischemic stroke is a rare condition that carries significant morbidity and mortality in comparison to other forms of stroke. It is usually associated with an anatomical variant with the thalamic paramedian arteries arising from a common trunk from the posterior cerebellar artery, known as Percheron artery. This infarct is difficult to be recognized and early recognition of this syndrome improves survival and functional recovery. We report a case of bilateral thalamic stroke after cardiac surgery.

Abstract:

The thalamus is a deep structure located in the diencephalon, whose arterial blood supply is mainly from four branches of posterior cerebral artery. The artery of percheron (AOP) is an infrequent variation of thalamic perfusion, occlusion of which presents with a heterogenous, atypical list of symptoms without focal signs. This is in contrast to the typical, easily recognizable focal neurology of other ischemic infarcts. Therefore, AOP infarctions may be misdiagnosed, delayed in diagnosis or missed altogether. It is a rare, but vital area of neurology that needs to be studied by clinicians to

Abstract:

The thalamus is a walnut-sized structure that is located in the brain which receives rich blood supply from posterior cerebral artery and its communicating branches. One of the unusual presentations is the infarction of artery of percheron. Hereby reporting a case of 68-year-old female with no known co-morbidities who presented to the emergency department with complaints of sudden onset loss of consciousness in the morning. On further investigation, was found to have infarction of one of the variants of thalamic perforating arteries.

Abstract:

ABSTRACT 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, characterised 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. We describe a 35-year-old male patient with no relevant medical history who was admitted to hospital with somnolence lasting for 1 week. The scans revealed symmetric bilateral paramedian thalamic hypodensity consis
