子宫动脉超声多普勒血流监测在妊娠期高血压疾病中的临床价值

目的：探讨妊娠期高血压疾病患者子宫动脉血流评分（UAS）与妊娠期高血压疾病患者围产期结果的关系。方法：对190例妊娠期高血压疾病患者（轻度80例，中度74例，重度36例）进行脐动脉和子宫动脉超声多普勒血流检测，并对子宫动脉超声多普勒血流进行评分。结果：子宫动脉血流异常比脐动脉血流异常更为常见（36．3％：10．2％）（P〈0．001）；随着病情进展，子宫动脉血流异常明显增多，但仍有68．8％的轻中度和41.7％的重度表现了正常的子宫动脉血流；随着UAS增高，剖宫产率明显增高、出生时孕周明显减低、出生体重显著下降、早产和小于胎龄儿发生率明显增加、转入新生儿监护中心发生率明显增加。结论：UAS是预测妊娠期高血压疾病不良围产期结果的早期且敏感指标；子宫胎盘循环病变可能不是妊娠期高血压疾病的唯一表现和原因。

Clinical significance of uterine artery Doppler velocimetry in pregnancy-induced hypertension

Objective: To study the relationship between uterine artery score(UAS) and perinatal outcome in women with(pregnancy-)induced hypertension(PIH).Methods: Uterine-umbilical artery Doppler velocimetry was performed in 190 cases of PIH,including 80 cases of mild PIH,74 moderate PIH,and 36 severe PIH.UAS was used to evaluate the uterine artery blood flow.Results: The incidence of abnormal uterine artery blood flow was higher than that of abnormal umbilical artery blood flow(36.3% vs.10.2%,P<0.05),and increased with the progression of PIH.The uterine artery blood flow was normal in 68.8% of the mild and moderate PIH and 41.7% of the severe PIH.With the increases of UAS,the rates of cesarean section,premature delivery,and admission to neonatal intensive care unit increased,and the gestational age at birth and birth weight decreased.Conclusion: UAS is an early and sensitive indicator to predict the perinatal outcome. Impaired placental circulation may be not the unique finding in PIH.
