超声动脉分析对妊娠高血压患者颈动脉血管的评价效果

目的:探究超声动脉分析技术应用于妊娠期高血压（PIH）患者，对评价颈动脉血管弹性及径向应变、应变率的效果分析。方法:回顾性分析2016年3月至2017年3月我院就诊的PIH患者36例作为观察组，另选同期来我院检查的50例正常妊娠孕妇作为对照组，采用彩色多普勒超声诊断仪配超声动脉评估定量分析软件追踪受试者颈动脉血管壁的运动，统计比较两组颈动脉弹性参数及径向应变（RS）、应变率（RSR）。结果:观察组孕妇的血管僵硬度β、脉搏波传导速度（PWV）明显高于对照组，而血管顺应性（AC）明显小于对照组，差异具有统计学意义（P<0.05）。两组反射波增强指数（AI）比较差异不显著（P>0.05）；观察组孕妇的RS和RSR明显低于对照组，差异具有统计学意义（P<0.05），Pearson分析结果显示观察组RS与PWV呈显著负相关（r=0-0.911，P<0.05）。结论:动脉分析技术应用于PIH可及时发现PIH血管弹性的变化，并在血管形态学未发生改变之前有效预防。RS和RSR均可作为反映PIH血管弹性变化的有效指标，且RS比RSR更加敏感。 

Evaluation of Carotid Artery in Patients with Pregnancy-induced Hypertension by Ultrasound Arterial Analysis

Objective To explore the effect of ultrasonic arterial analysis on the evaluation of carotid artery elasticity, radial strain and strain rate in patients with pregnancy-induced hypertension syndrome (PIH). Method Retrospectively analyzed 36 patients with PIH, who were treated in our hospital between March 2016 and March 2017, as the observation group. At the same time selected 50 cases of normal pregnancy that were checked in our hospital over the same period as the control group. Applied color Doppler ultrasonic diagnostic instrument and ultrasonic artery assessment quantitative analysis software to track the movement of carotid artery wall in subjects. Made a statistics comparison of the elastic parameters of carotid artery, Radial Strain (RS) and Radial Strain Rate (RSR) of two groups. Results: The blood vessels stiffness β and Pulse Wave Velocity (PWV) of pregnant women in the observation group were significantly higher than those of the control group. However, the Arterial Compliance (AC) was significantly smaller than that of the control group, and the difference was statistically significant (P<0.05), There was no significant difference in the Augmentation Index (AI) (P>0.05) between the two groups, The RS and RSR of pregnant women in the observation group were significantly lower than those in the control group, and the difference was statistically significant (P<0.05). Finally, the Pearson analysis showed that there existed significant negative correlation between RS and PWV of the observation group (r=0-0.911, P<0.05). Conclusion It can timely find the change of PIH vascular elasticity to apply artery analysis technique in PIH. And it can effectively prevent before the vascular morphology do not change. RS and RSR can be used as effective indicators to reflect the changes of vascular elasticity of PIH, and RS is more sensitive than RSR.
