应用国产微机导纳脑血流图检测脑血流量的初步报告

Preliminary Report of Detecting Cranial Blood Flow by Computer Admittance Encephalo hemorrheology

用国产ＨＮＣＰＡ－２仪检测６９例无脑部疾患成年人的分钟全脑血流量（ＣＢＦ），结果平均预测值６７５±８１ｍｌ，实测值６１７±１０４ｍｌ，位于理论值正常范围的下限。年龄对ＣＢＦ的影响最为显著，全脑及４支动脉的ＣＢＦ随年龄增加而渐降低，动脉硬化发生率渐上升，其中以椎动脉最明显。本方法属无创技术，操作较简单，能客观反映被检者ＣＢＦ，可在临床用作动态观察。

The cranial blood flow(CBF)was monitored with HNCPA 2 machine in 69 adults.The estimated CBF was 675±81ml/min and that deteced was 617±104ml/min, which was somewhar lower than the normal results on the texbook. The most important effecting factor of CBF was age. As age increased, CBF decreased and incidence of artery scolerosis,especially in vertebral artery, was increased.The authors suggcst that this non inasive method is simple to operate and can detect dynamically the CBF clinically.
