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.
放射影像学在诊断 Percheron 动脉（AOP）梗死中很重要。本研究旨在探讨这种异常动脉供血变异的磁共振成像（MRI）表现。回顾性评估了 2010 年至 2019 年期间因中风症状就诊于我院并接受脑部 MRI 检查的患者。研究纳入了 11 例 AOP 梗死患者。患者的平均年龄为 67.4±9.6 岁。7 例（63.6%）为男性，4 例（36.4%）为女性。8 例（72.7%）患者伴有高血压，5 例（45.4%）患者伴有冠心病。8 例（72.3%）患者 AOP 下壁梗死，90.9%的患者出现缺血性损伤的不对称影像学模式。随着血管内卒中治疗的广泛应用，快速准确地诊断卒中以实现无后遗症恢复变得至关重要。因此，尽管 AOP 梗死很少见，但由于可能的发病率和死亡率，快速准确的诊断很重要，可以通过 MRI 进行。
