摘　　要：目的:研究大脑前动脉供血区梗死的临床及影像学特点以指导临床工作。方法:对22例确诊大脑前动脉供血区梗死患者的临床资料进行回顾性分析,其中12例应用简易智能量表(MMSE)或蒙特利尔认知评估北京版量表(MoCA)评定认知功能。结果:本组22例大脑前动脉供血区梗死患者以胼胝体(16例)、额叶内侧面(16例)受累最多。肢体乏力(20例)为最常见症状,其中以下肢为重的偏瘫(7例)和单肢瘫(4例)最常见,其他临床表现包括意志减退/淡漠(12例)、排尿障碍(10例)、感觉减退(7例)、失语(3例)等。12例完善MMSE或MoCA量表患者中有8例存在认知功能缺损。结论:大脑前动脉供血区梗死患者临床表现多样,应加强鉴别诊断。Aim：To investigate the clinical manifestation and neuro-imaging changes of infarction in the territory of anterior cerebral artery（ACA） to guide the clinical work.Methods：The clinical data of 22 patients who were diagnosed ACA infarction were analyzed.Among them,cognitive functions were examined in 12 patients using Mini-Mental State Examination（MMSE） or Montreal Cognitive Assessment Beijing Version （MoCA）.Results：In the 22 ACA infaction patients,corpus callosum（n=16） and interior side of frontal lobe （n=16） were most frequently affected.The most common symptom was motor dysfunction（n=20）,in which leg weakness dominant hemiparesis（n=7） and leg monoparesis（n=4） were the main form.Other manifestations include hypobuli/indifference（n=12）,urinary disorder（n=10）,sensory defect（n=7） and aphasia（n=3）.Among the 12 patients whose cognitive functions were examined,8 persons showed cognitive dysfunction. Conclusion：There are various clinical features of ACA infarction,and identifying this particular territory of brain infarction should be careful.
