To correlate uterine artery Doppler findings with maternal and neonatal outcomes in early- and late-onset preeclampsia with severe features.
Doppler scan was done in both uterine arteries. Maternal and neonatal outcomes in women with abnormal and normal Doppler results were compared.
Abnormal Doppler results were present in 45 women (75%). Thirty-four (56.7%) women had abnormal RI, 19 (31.6%) had abnormal PI, and 36 (60%) had diastolic notch. Of the women who participated in the study, 21.6% developed maternal complications, and the majority belonged to the early-onset severe preeclampsia group. Diastolic notch was twofold more frequent in the early group. RI was abnormal in 63% of the early-onset and 50% of the late-onset group.
Pregnancies with early-onset preeclampsia who had abnormal uterine artery Doppler findings were at high risk for both maternal and neonatal complications, whereas those who had late-onset preeclampsia with abnormal Doppler findings only had an increased risk of perinatal complications.
探讨早发型和晚发型重度特征子痫前期患者子宫动脉多普勒表现与母婴结局的相关性。
对所有患者的子宫动脉进行多普勒扫描。比较子宫动脉多普勒结果异常和正常患者的母婴结局。
45 例（75%）患者子宫动脉多普勒结果异常。34 例（56.7%）患者 RI 值异常，19 例（31.6%）患者 PI 值异常，36 例（60%）患者出现舒张末期切迹。研究中，21.6%的患者出现了母体并发症，大多数属于早发型重度子痫前期组。早发型组出现舒张末期切迹的比例是晚发型组的两倍。早发型组中，63%的患者 RI 值异常，晚发型组中，50%的患者 RI 值异常。
早发型子痫前期患者子宫动脉多普勒检查异常，其母婴均有较高的并发症风险，而晚发型子痫前期患者子宫动脉多普勒检查异常，仅围产儿并发症风险增加。
