摘要
本文用经颅多普勒(TCD)检测健康人和轻、重型脑动脉硬化患者颅内主要动脉的时相(S_1、S_2峰α角),搏动指数(PⅠ).并与临床特点和眼底动脉硬化改变作对比研究。发现脑动脉硬化组同期TCD各项观察指标与健康组相比有显著性差异,重型与轻型相比有显著性差异,老年期与老年前期患者相比有显著性差异。伴有高血压者主要为PⅠ增大与眼底动脉硬化,而不伴高血压者主要为S_1<S_2α角变锐。提示TCD可弥补脑动脉硬化的临床与眼光底改变之不足,对脑动脉硬化的诊断及亚临床或早期脑动脉硬化的发现有一定价值。
The systolic peak time (S_1, S_2,a corner). pulse index (PI) of main intracranialarferies in healthg persons and the Patients with mild or severe arteriosclerosisexamined by transcranial dopper (TCD) were analyzes and comparatively studiedwith clinical charalteristics and arterioscleroric changes of ocular fandus. The resulfshowed that the variables in TCD. of cerabral arteriosclerosis group were quitedifferent from that of healthy gnoup, severe defferent from mild, aged defferentfrom preaged. In hypertensives the main manifastation were the in creuse of PI andocular fundus arteriosclerosis and in nonhypertensives were the S_1<S_2 and sharpenof α corner. The results suggest that TCD can Complete the clinical characteristics and ocular fundus changes in cerebral arteriosclerosis patients and may be valuable inthe diagnosis of cerebral ateriosclerosis and early discovery of subclinical or earlycerebral ateriosclerosis.
