32例皮质下动脉硬化性脑病分析

Subcortial Arteriosclerotic Encephalopathy (An Analysis of 32 Cases)

本文对我院自1990～1994经CT证实为皮质下动脉硬化性脑病32例进行回顾性分析。本病发病机理主要是脑深部白质深穿支动脉硬化引起血液准流量减少，导致深部白质缺血性脱髓鞘和微梗塞。智能障碍往往为首发症状，CT、MRI是本病诊断理想方法，控制和预防高血压是治疗的关键。

32 cases with Subcotial artreiosclerotic encephalopathy (SAE ) diagnosed by CT from 1990 - 1994 in our hospital were analysed retrospectively. The major pathogenesis of SAE was the decreased blood perfusion of the cleep white matter due to arteriosclerosis of deep branch, thus leading to ischenlic demyelimation and microthrombosis in the deep white matter. SAE, with initial symptom of the disorder of mental intelligence, was mainly diagnosed by CT and MRI,and the control and prevention of hypertension were the key of treatment.
