目的 探讨彩超检测妊高征（ＰＩＨ）孕妇肾内动脉（ＩＲＡ）血流指数的临床应用价值。方法 应用彩超检测４６例ＰＩＨ孕妇ＩＲＡ 的搏动指数（ＰＩ）、阻力指数（ＲＩ）， 并与１８６例正常孕妇进行对照。 结果①ＰＩＨ 孕妇ＩＲＡ的ＰＩ、ＲＩ较正常孕妇明显升高（Ｐ＜ ０．００１）， 且中重度ＰＩＨ孕妇ＩＲＡ的ＰＩ较轻度ＰＩＨ进一步升高（Ｐ＜ ０．００１）； ②ＰＩＨ孕妇ＩＲＡ的ＰＩ、ＲＩ与ＰＩＨ分类（Ｐ＜ ０．００１）、尿蛋白量（Ｐ＜ ０．０１）、平均动脉压（Ｐ＜ ０．０５）成一定程度正相关， 且以ＰＩ的相关性最好。结论 彩超检测ＰＩＨ孕妇ＩＲＡ的Ｄｏｐｐｌｅｒ血流指数对临床观察、治疗ＰＩＨ具有一定的参考意义， 其中ＰＩ可能为更好的观察指标
Objective To explore the clinical value of detecting the blood flow index of renal artery (IRA) in pregnant women with PIH by color Doppler ultrasound. Methods The pulsatility index (PI) and resistance index (RI) of 46 PIH pregnant women were detected by color Doppler ultrasonography and compared with 186 normal pregnant women. Results ① The PI and RI of IRA in pregnant women with PIH were significantly higher than those in normal pregnant women (P <0.001), and the PI of IRA in pregnant women with moderate and severe PIH were higher than those with mild PIH (P <0.001) , RI and PIH classification (P <0.001), urinary protein content (P <0.01), mean arterial pressure (P <0.05) had a certain degree of positive correlation, and PI had the best correlation. Conclusion Color Doppler ultrasound examination of PIH pregnant women with IRA Doppler blood flow index for clinical observation, treatment of PIH has some reference value, PI may be a better indicator
