Abstract

Background: Placental dysfunction is one of the main causes of preeclampsia and hypertensive disorders of pregnancy.

Material and methods: This is a prospective comparative study done on 30 pregnant women with pre-eclampsia and another 30 pregnant women as controls. In all these subjects the elasticity of the placenta was measured.

Results: The results obtained showed that there was a significant difference in SWV values between the two groups (p value = 0.001). The mean SWV value of normal pregnant women was 0.99 m/ second as opposed to 1.99 m/second in pre-eclamptic pregnant women.

Conclusion: Sonoelastography is a promising noninvasive tool in the detection of preeclampsia with high diagnostic accuracy. The SWV values measured at the central zones of the placenta with a cut-off value of 1.325 m/s identify the presence of pre-eclampsia with high sensitivity and specificity.

胎盘声辐射力脉冲弹性成像在诊断子痫前期中的作用。

背景：胎盘功能障碍是导致子痫前期和妊娠高血压的主要原因之一：胎盘功能障碍是导致子痫前期和妊娠高血压疾病的主要原因之一：这是一项前瞻性比较研究，研究对象是30名患有子痫前期的孕妇和另外30名对照组孕妇。对所有这些受试者的胎盘弹性进行了测量：结果显示，两组孕妇的 SWV 值差异显著（P 值 = 0.001）。正常孕妇的平均 SWV 值为 0.99 米/秒，而先兆子痫孕妇的平均 SWV 值为 1.99 米/秒：结论：超声弹性成像是一种很有前途的无创检测工具，在检测子痫前期方面具有很高的诊断准确性。在胎盘中心区测量的 SWV 值（临界值为 1.325 米/秒）能以较高的灵敏度和特异性确定是否存在子痫前期。
