Can placental shear wave elastography predict preeclampsia in high-risk pregnant women during second trimester? Insights from a prospective cohort study
Abstract Background Preeclampsia, a condition very frequently linked to maternal and fetal deaths worldwide, remains a pressing concern due to delays in recognition and response. Effective screening tests for early detection of high-risk cases and appropriate preventive measures are currently lacking. Well planned prenatal care, timely detection, monitoring, and appropriate management are vital to prevent preeclampsia-related fatalities. Methods This prospective study evaluated the use of shear wave elastography (SWE) in identifying placental structural issues caused by preeclampsia in high-risk pregnancies. A total of 143 high-risk pregnant women with singleton pregnancies and an anterior placental position were included in the study. Results Women with preeclampsia exhibited significantly elevated SWE values in both center (27.98 ± 16.12 vs. 4.57 ± 6.57 kPa) and peripheral areas of the placenta (29.14 ± 16.12 vs. 4.80 ± 7.70 kPa) when compared to non-preeclampsia women (p = 0.000). Cutoff values of 8.70 kPa and 8.15 kPa at the Center and edge of the placenta respectively, accurately predicted preeclampsia in second-trimester pregnancies, with 84.62% sensitivity and 94% specificity. However no significant difference was observed between elastography values obtained from the center and edge of the placenta. Conclusions In conclusion, shear wave elastography can help diagnose preeclampsia early by assessing placental stiffness.
