目的:分析心源性脑栓塞(cardiogenic cerebral embolism,CCE)的病因及影像学特点.方法:对100例心源性脑栓塞患者既往史、临床表现、心电图、超声心动图、CT、MRI进行分析.结果:心房纤颤84例,占84%;风湿性心脏瓣膜病伴心房纤颤21例,占21%;非风湿性心脏瓣膜病伴心房纤颤63例,占63%;头颅磁共振检查提示大面积脑梗死76例占76%,合并出血性梗死23例,占23%.结论:心房纤颤是引起心源性脑栓塞的最常见原因,其中大多数为非瓣膜病性心房纤颤,心源性脑栓塞约76%为大面积梗死,而且病灶累及多叶,易发生出血性梗死.%Objective: To analyze the mechanism and the clinical imaging features of cardiogenic cerebral embolism (CCE). Methods: We retrospectively reviewed the records of 100 CCE patients who had undergone ECC, echocardiogram,computetized tomography (CT) and magnetic resonance imaging (MRI) evaluation. Results: Among 100 CCE patients,eighty four percent patients had atrial fibrillation, and Vulvular-atnal fibrillation account for sixty three percent, seventy six percent patients magnetic resonance imaging (MRI) demonstrate large area infraction, twenty three percent patients appear hemorrhagic infraction. Conclusion: Atrial fibrillation is the most common cause of CCE. Non-vulvular-atrial fibrillation more common, seventy six percent CCE patients magnetic resonance imaging demonstrate large area infarction and CCE patients is prone to hemorrhagic infarction (HI).
