The causes of ischaemic brain damage are numerous. Four main groups are described: atherosclerotic disease of the cervical and intracranial arteries represents 50% of the causes, small vessel disease with lacunar infarcts 25%, cardio-embolic disease 20% and non-atheromatous arterial disease and blood dyscrasias 10%. In 10% of cases, no etiology is identified. MRI has a dominating place in the etiologic assessment of cerebral infarction, by distinguishing the various types of infarction, detecting associated abnormalities like leukoencephalopathy and haemorrhage and by analyzing the lumen and wall of vessels.
缺血性脑损伤的病因众多。主要分为四类:颈内和颅内动脉粥样硬化疾病占病因的50%,伴有腔隙性梗死的小血管疾病占25%,心源性栓塞疾病占20%,非动脉粥样硬化性动脉疾病和血液系统疾病占10%。在10%的病例中,未查明病因。磁共振成像(MRI)在脑梗死的病因评估中占据主导地位,它可以区分不同类型的梗死,检测如白质脑病和出血等相关异常,并分析血管的管腔和管壁。
