摘要目的:探讨妊娠期子宫动脉彩色多普勒频谱表现与不良妊娠结局的关系。方法:147例24～38周单胎妊娠妇女,正常妊娠115例,不良妊娠结局者32例,均进行子宫动脉彩色多普勒检查,测定搏动指数(PI),观察有无舒张早期切迹,将它们进行比较分析。结果:(1)孕妇发生早产、重度妊娠期高血压、胎儿生长受限(FGR)以及新生儿出生后1 min Apgar评分<7分等不良妊娠结局者的PI值较正常组增高,双侧舒张早期切迹发生率亦明显增高,差别有统计学意义(P<0.01);(2)轻度妊娠期高血压子宫动脉PI值和舒张早期切迹与正常组比较无明显差别(P>0.05)。结论:子宫动脉PI值增高尤其同时伴有舒张早期切迹时,提示孕妇发生异常妊娠结局可能性大;彩色多普勒检查对重度妊娠期高血压子宫动脉监测价值大于轻度妊娠期高血压。 Aim： To explore the relationship between pregnant uterine artery waveforms measured by color Doppler ultrasound and adverse pregnancy outcome. Methods： One hundred and forty-seven cases pregnant women at 24 - 38 weeks gestation were examined by color Doppler ultrasound, composed of 115 cases of normal pregnancy outcome and 32 cases of adverse pregnancy outcome. Pulsatility indices （PI） value and the presence of notches in the spectra of uterine artery were compared between normal pregnancy outcome group and adverse pregnancy outcome group. Results： PI value and rate of finding early diastolic notch of uterine artery were significantly higher in adverse pregnancy outcome group which happened pre- term delivery, severe pregnancy-induced hypertension, fetal growth retardation, 1 minute Apgar scores 〈 7 than in normal pregnancy outcome group. But there was no statistically significant difference in PI value and rate of finding early diastolic notch of uterine artery between mild pregnancy-induced hypertension group and normal pregnancy outcome groups. Conclusion：The pregnant women who get high PI value and have early diastolic notch of uterine artery have higher probability of happening adverse pregnancy outcome. And color Doppler has a higher value in monitoring pregnant women who get severe pregnancy-induced hypertension than in mild pregnancy-induced hypertension.
