Abstract
Artery of Percheron is an anatomical version of the cerebral vessels, 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 brain infarction is often manifested by impaired consciousness, oculomotor disorders and neuropsychological symptoms. The diagnosis of the Artery of Percheron brain infarction is carried out using computed and/or magnetic resonance imaging (MRI). Intravenous thrombolysis and endovascular treatment methods are used in therapeutic window. Further secondary prevention is recommended. The prognosis is favorable with the timely treatment.
A clinical case of a 43-year-old woman with acute oculomotor disorders is presented. A neurological examination revealed paresis of the vertical gaze, diplopia. MRI showed a bilateral acute infarction of both paramedial thalamuses. An angiographic study revealed saccular aneurysm of the A1 segment of the right anterior cerebral artery. After treatment, the patient was discharged with minimal neurological deficit.
