Abstract:

La arteria de Percheron corresponde a una variante anatómica rara originada de la arteria cerebral posterior. Su oclusión produce un infarto talámico paramediano bilateral y podría involucrar el mesencéfalo rostral, esto da origen un síndrome clínico caracterizado por alteración del estado de conciencia y déficit cognitivo. Sin embargo, existe un retraso diagnóstico importante en esta patología. Se presenta el caso de un paciente masculino de 52 años, que inicia con una alteración súbita del estado de conciencia, en quien se documentaron hallazgos compatibles con Síndrome de la arteria de Perc

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

Abstract:

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.

Abstract 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. 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:

Ischemic stroke caused by the obstruction of the artery of Percheron is a rare type of ischemic stroke, in which one arterial branch supplying blood to both thalamuses and the middle brain is occluded, which leads to the depression of consciousness, paresis of vertical vision, and cognitive impairment. Due to the atypical symptoms ("stroke-chameleon"), the diagnosis is often not verified in time, which deprives the patient of the most effective treatment – thrombolytic therapy. The review aims to increase clinicians' awareness of this subtype of stroke.

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 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.

Abstract:

AbstractThe artery of Percheron (AOP) is an abnormal variant of the arterial supply of the thalamus. Stroke caused by AOP occlusion is seldom reported. AOP leads to bilateral thalamic and rostral midbrain infarct presenting with unspecific manifestations. There are few descriptions of case series of stroke caused by AOP. We sought to review the clinicoradiological characteristics of AOP infarction from Algarve, Southern Portugal. Eight consecutive cases were retrospectively identified by searching the electronic clinical charts, as well as the stroke Unit database (2015–2020). Sociodemographic

Abstract:

Artery of Percheron (AOP) is an abnormal variant of the arterial supply of the thalamus. 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:

The thalamus is a part of the arousal system; its infarction can lead to varying levels of impaired consciousness (from hypersomnia to coma). It is mainly supplied by small perforating arteries arising from the posterior cerebral artery (PCA). There are several variants of this vascularization, the artery of Percheron (AOP) is one of those variants which takes the form of a solitary arterial trunk that arises from one of the proximal segments of the PCA and bifurcates to supply both paramedian thalami. Its occlusion results in bilateral paramedian thalamic infarction with or without midbrain i

Abstract:

Rationale: Bilateral thalamic infarction is a rare type of posterior circulation stroke, and it often presents with a reduced level of consciousness in the elderly. Arteriosclerosis is the primary etiology of bilateral thalamic infarction, including conditions such as native vessel stenosis or arterial-to-arterial embolism. Cardiogenic or paradoxical embolism can also lead to thrombosis of the perforator branches innervating the thalamus, and these emboli tend to disintegrate and lead to multiple lesions, even in elderly patients.
