Association with clinic risk factors of Percheron artery infarction and magnetic resonance imaging involvement patterns

Abstract

Radiological imaging is important in the diagnosis of the artery of Percheron (AOP) infarction. This study aimed to discuss the magnetic resonance imaging (MRI) findings of this abnormal variant of arterial supply. Patients who presented to our hospital with stroke symptoms between 2010 and 2019 and underwent brain MRI were evaluated retrospectively. Eleven patients with AOP infarction were included in the study. The mean age of the patients was 67.4 ± 9.6 years. Seven (63.6%) of the patients were male and four (36.4%) were female. Accompanying diseases were hypertension in eight patients (72.7%) and coronary artery disease in five (45.4%). In eight patients (72.3%), the infarction of AOP extended under the third ventricle wall, and 90.9% of the patients had an asymmetrical radiographic pattern of ischemic damage. With the widespread use of endovascular stroke treatment, it has become critical to establish a rapid and accurate diagnosis of stroke to achieve recovery without sequela. Therefore, although the infarction of AOP is rare, a rapid and accurate diagnosis is important due to possible morbidity and mortality and can be undertaken using MRI.
