为了能预测脑动静脉畸形(AVM)病人手术治疗的病残和死亡危险性的大小,作者提出一种对AVM 病人普遍适用的简化分级评分法。此方法是根据AVM 的三个基本要素——病变的大小、静脉引流方式、是否邻近脑重要功能区——而将所有的AVM 分为五级。其三个基本要素则根据脑血管造影、CT 扫描及磁共振成像综合分析得 In order to predict the size of the morbidity and mortality of surgical treatment of patients with cerebral arteriovenous malformation (AVM), the authors propose a simplified graded score that is generally applicable to patients with AVM. This method is based on the AVM’s three basic elements - the size of the lesion, venous drainage, whether adjacent to the brain’s important functional areas - and all AVM is divided into five. The three basic elements are based on comprehensive analysis of cerebral angiography, CT scan and magnetic resonance imaging
