In this report we assess the systolic maximal flow velocity in carotid and intracranial arteries in 191 subjects with no history of cerebral vascular disease in 3 age groups: 20-40 years (1 group), 41-60 years (2 group), and above 60 years (3 group). The subjects were assessed using Sonomed Transcranial Doppler Spectrograph according to generally accepted principles. The purpose of the study was to establish the mean value of maximal flow velocity in each particular artery in three age groups, and to observe the changes in this parameter with age. The results were analyzed using statistical methods and a significant decrease in blood flow, Vmax, was found in all investigated arteries. A mean decrease of 8.02% in flow velocity Vmax was found, when comparing groups 2 and 1, and difference 15.99% comparing 3 and 1.
在本报告中，我们评估了191名无脑血管疾病史的受试者的颈动脉和颅内动脉的收缩期最大流速，这些受试者分为3个年龄组：20 - 40岁（第1组）、41 - 60岁（第2组）和60岁以上（第3组）。根据普遍接受的原则，使用索诺美经颅多普勒频谱仪对受试者进行评估。本研究的目的是确定三个年龄组中各特定动脉最大流速的平均值，并观察该参数随年龄的变化。使用统计方法对结果进行分析，发现所有被研究动脉的血流（Vmax）均显著下降。比较第2组和第1组时，流速Vmax平均下降了8.02%，比较第3组和第1组时，差异为15.99%。
