Artery of percheron infarction of the brain: clinical case

Abstract

Background. The artery of Percheron is an anatomical version of the cerebral vasculature, in which one artery, departing from the proximal part of one of the posterior cerebral arteries, supplies the paramedial thalamus and the rostral part of the midbrain. The artery of Percheron stroke is often manifested by impaired consciousness, oculomotor disorders and neuropsychological symptoms. The diagnostics of the artery of Percheron stroke is carried out using computed tomography and/or magnetic resonance imaging (MRI). Intravenous thrombolysis and endovascular treatment methods are used upon admission within the “therapeutic window”. Further secondary prevention is recommended. The prognosis is favorable with the timely treatment. Clinical case description. A clinical case of a 43-year-old woman with acute oculomotor disorders is presented. The neurological examination revealed paresis of the vertical gaze, diplopia. MRI showed a bilateral acute infarction of both paramedial thalamuses. After the treatment, the patient was discharged with a minimal neurological deficit. Conclusion. Percheron artery occlusion is a rare form of cerebral infarction. Early diagnosis, in particular neuroimaging and angiography, allows for a timely adequate treatment, which has a positive effect on the rehabilitation.
