彩色多普勒超声检测子宫螺旋动脉预测妊娠高血压综合征

Detection of Uterine Spiral Artery by Color Doppler Ultrasound to Predict Pregnancy Induced Hypertension Syndrome

目的探讨彩色多普勒超声(以下简称“彩超”)检测子宫螺旋动脉对于预测妊娠高血压综合征(pregnancy-induced hypertension,PIH)的价值。方法选取2021年1月—2022年2月接受彩超检查的200名孕妇为研究对象,根据孕妇是否患PHI分成疾病组(n=59)与正常组(n=141)。所有孕妇均是在孕16~20周、孕24~28周、孕32~36周3个阶段接受彩超检查,检查并且记录两组孕妇子宫螺旋动脉收缩期峰值流速与舒张末期血流速度比值(peaksystolic velocity/end diastolic ve⁃locity,S/D)、平均搏动指数(pulsatility index,PI)及血流阻力指数(resistance index,RI)指标,同时检测血压指标。结果孕16~20周疾病组的孕妇子宫动脉、螺旋动脉在S/D[(2.35±0.64)、(2.01±0.62)]、PI[(0.77±0.21)、(0.56±0.12)]、RI[(0.51±0.13)、(0.53±0.15)]高于正常组,差异有统计学意义(t=6.216、3.468、9.521、9.656、5.617、5.240,P<0.05),孕24~28周疾病组的孕妇子宫动脉、螺旋动脉血流动力学参数高于正常组,疾病组孕妇在孕16~20周、孕24~28周、孕32~36周的收缩压、舒张压水平上均是显著高于正常组,差异有统计学意义(P<0.05)。结论针对孕产妇应用彩超检测子宫螺旋动脉,可测定血流动力学指标,这对预测PIH的效果满意,为疾病早期诊治提供有利参考借鉴。

Objective To explore the value of color Doppler ultrasound(hereinafter referred to as"color Doppler ultrasound")in detecting uterine spiral artery in predicting pregnancy induced hypertension syndrome(PIH).Methods 200 pregnant women who underwent color Doppler ultrasonography from January 2021 to February 2022 were selected as the research object.Ac⁃cording to whether pregnant women suffered from phi,they were divided into disease group(n=59)and normal group(n=141).All pregnant women were examined by color Doppler ultrasound at 16-20 weeks of pregnancy,24-28 weeks of pregnancy and 32-36 weeks of pregnancy.The ratio of peak systolic velocity to end diastolic velocity(S/D),mean pulsatility index(PI)and blood flow resistance index(RI)of uterine spiral artery in the two groups were examined and recorded,and blood pressure was measured at the same time.Results The S/D[(2.35±0.64),(2.01±0.62)],PI[(0.77±0.21),(0.56±0.12)]and RI[(0.51±0.13),(0.53±0.15)]of uterine artery and spiral artery in the disease group at 16-20 weeks of pregnancy were significantly higher than those in the normal group,the difference was statistically significant(t=6.216,3.468,9.521,9.656,5.617,5.240,P<0.05).The uterine ar⁃tery and spiral artery in the disease group at 24-28 weeks of pregnancy were higher than those in the normal group,the levels of systolic and diastolic blood pressure in the disease group were significantly higher than those in the normal group at 16-20 weeks,24-28 weeks and 32-36 weeks,the difference was statistically significant(P<0.05).Conclusion For pregnant women,the application of color Doppler ultrasound to detect uterine spiral artery can measure hemodynamic indexes,which is satisfactory for the prediction of PIH,provides a favorable reference for early diagnosis and treatment of diseases.
