目的 探讨彩超对孕妇眼动脉的A峰及B峰的血流速度、B/A值、搏动指数 (PI)、阻力指数 (RI)检测在临床观察妊娠高血压综合征 (妊高征 )中的价值。方法 测定 42例妊高征孕妇眼动脉血流参数 (B/A、PI、RI)并与 90例正常孕妇作对照分析以观察血流参数变化。结果 妊高征患者眼动脉血流频谱特征为 :B峰、B/A值较正常孕妇明显升高 (P <0 .0 0 1) ,而PI、RI较正常孕妇明显下降 (P <0 .0 0 1)。结论 所测血流参数具有较高的阳性预测值、阴性预测值 ,对妊高征孕妇的早期诊断及预后判断具有较高的临床价值
Objective To investigate the effect of color Doppler ultrasonography on the blood flow velocity, B / A value, pulsatility index (PI) and resistance index (RI) in pregnant women with pregnancy induced hypertension (PIH) value. Methods The ophthalmic arterial blood flow parameters (B / A, PI, RI) of 42 pregnant women with PIH were measured and compared with 90 normal pregnant women to observe the changes of blood flow parameters. Results The frequency spectrum of ophthalmic artery blood flow in patients with PIH was: B peak, B / A value was significantly higher than that of normal pregnant women (P <0.01), while PI and RI were significantly lower than those of normal pregnant women (P <0. 0 0 1). Conclusions The measured blood flow parameters have high positive predictive value and negative predictive value and have high clinical value in the early diagnosis and prognosis judgment of pregnant women with PIH
