高血压病126例经颅多普勒脑血流测定临床分析

目的　探讨经颅多普勒脑血流测定对高血压病诊断和分期的价值。方法　对 1 2 6例高血压病患者 ,采用经颅多普勒仪探测大脑中动脉、大脑前动脉及大脑后动脉 ,记录平均血流速度 ,测定结果进行统计分析。结果　高血压病 期组 ,病程较短 ,年龄较轻者 ,各颅内血管的 Vm值与对照组比较无显著差异。 期组 ,各颅内血管的 Vm值明显增快。 期组 ,病程较长 ,年龄较大者 ,各颅内血管的 Vm值明显减慢。结论　TCD测值改变提供了高血压病诊断和分期的重要辅助指标。

Clinical Analysis of TCD and Determination of Cerebral Blood Flowin 126 Patients with Hypertension

Objective To explore the valuation of transcranial doppler (TCD) and determination of cerebral blood flow in diagnosis and stages analysis of hypertension Methods We used TCD to detect middle cerebral artery (MCA), anterior cerebral artery (ACA), and posterior cerebral artery (PCA) of 126 patients with hypertension, measured the mean velocity (Vm) of blood flow The data obtained from this study was analyzed with statistical method Results Compared with the control group, the Vm values of cerebral blood arteries had no significant difference in the patients with relatively short course of diseases and relatively young in the hypertension stage Ⅰ group The Vm values of cerebral blood arteries markedly quicken in the hypertension stage Ⅱ group The Vm values of cerebral blood arteries were markedly slower in the patients with relatively long course of diseases and relatively old in the hypertension stage Ⅲ group Conclusion Changing in measure values of TCD provided an important assistant index in diagnoses and stages analysis of hypertension
