慢性皮质下动脉硬化性脑病的CT与临床(附30例分析)

目的　探讨皮质下动脉硬化性脑病的病因、发病机制、诊断和治疗、影像学表现。方法　回顾性分析 30例临床及头部CT诊断为皮质下动脉硬化性脑病的患者。结果　 (1 )均有 5～ 4 4年不等的高血压病史 ,部分伴有多年吸烟史或伴Ⅱ型糖尿病史者病情较重 ;(2 )脑CT均表现有不同程度的白质疏松 (LA)及深部白质软化灶、侧脑室扩大。结论　Binswanger(BD)病的直接病因即是高血压。对有长期高血压和进展性痴呆 ,伴有多发性腔隙卒中者 ,结合脑CT改变可考虑本病诊断 ,应强调智能障碍 ,而不应过分强调痴呆。及时给予治疗 ,可延缓病程

Diagnosis of Subcortex Arteriosclerotic Encephalopathy
