摘　　要：目的探讨Percheron动脉梗死的影像学和临床特征。方法对10例Percheron动脉梗死患者的临床表现、影像学资料、治疗和预后进行分析。结果10例患者均急性起病且存在不同程度意识障碍，其中垂直注视麻痹3例，语言障碍3例，肢体无力6例，记忆缺损4例。IVIRI均显示双侧丘脑梗死，1例可见“中脑V字征”，1例脑血管造影发现Percheron动脉闭塞。10例均病情好转出院，但存在不同程度的后遗症。结论Percheron动脉梗死极为少见，诊断主要依据临床表现和影像学检查，脑血管造影可确诊本病。Objeelive To investigate the imaging and clinical features of Percheron artery infarction. Melhods The clinical manifestations, imaging data, treatment, and prognosis of 10 patients with Percheron artery infarction were analyzed. R.esults All 10 patients had acute onset and had different degrees of consciousness disorders, including vertical gaze palsy （n = 3）, language disorder （n = 3）, limb weakness （n = 6）, and memory impairment （n = 4）. MRI showed bilateral thalamus infarction. ＂Midbrain V-sign＂ in one patient was observed. Cerebral angiography revealed that one patient had Percheron artery infarction. All 10 patients were improved and discharged, but left with varying degrees of sequelae. Conclusions Percheron artery infarction is rare in clinical practice. The diagnosis is mainly based on clinical manifestations and imaging examinations. Cerebral angiography can diagnose the disease.
