摘要
目的探究胎儿动脉导管狭窄应用产前超声检查的诊断价值。方法临床选择2014年1月‐2016年4月该院经产前彩色多普勒超声检查的胎儿动脉导管狭窄孕妇50例为观察组,同期选择产前彩色多普勒超声检查健康胎儿50例为研究对照,比较两组动脉导管的舒张期流速、收缩期流速及动脉导管内径等临床指标;比较两组动脉导管前向血流速度、三尖瓣反流速度及右心室压力等临床指标;观察在不同超声切面动脉导管的超声特征。结果在25~36孕周和孕周超过36周孕妇中,观察组舒张期流速、收缩期流速等指标显著高于对照组,差异有统计学意义(P<0.05);观察组胎儿动脉导管内径小于对照组,差异有统计学意义(P<0.05);在孕25~36周和超过36周观察组动脉导管前向血流速度、三尖瓣反流速度及右心室压力均显著高于对照组,差异有统计学意义(P<0.05)。结论胎儿产前彩色多普勒超声检查可全面、客观评估其影像特征,对诊断胎儿动脉导管狭窄具有重要的临床价值。
【Objective】To study the value of prenatal ultrasound in diagnosis of fetal ductus arteriosus stenosis.【Methods】？Fifty cases of fetal ductus arteriosus stenosis diagnosed by prenatal color Doppler ultrasound in our hospital from January 2014 to April 2016 were selected as the observation group,and 50 healthy fetuses were selected by prenatal color Doppler ultrasound as the control group,the clinical indexes such as the diastolic flow velocity,the systolic flow velocity,and the diameter of the ductus arteriosus were compared between the two groups;the arterial velocity,the velocity of three cusp regurgitation,and the pressure of the right ventricle were compared between the two groups;the ultrasonic characteristics of the ductus arteriosus in different ultrasonic sections were observed.【Results】During the 25~36 week gestation and 36 week gestation,the diastolic flow velocity and systolic flow velocity of the observation group were significantly higher than those of the control group,and the differences were statistically significant（P〈0.05）;the diameter of fetal ductus arteriosus in the observation group was smaller than that in the control group,and the difference was statistically significant（P〈0.05）;at the 25~36 week of gestation and more than 36 weeks,the blood flow velocity,the three tricuspid regurgitation velocity and the right ventricular pressure in the observation group were significantly higher than those in the control group,and the differences were statistically significant（P〈0.05）.【Conclusion】Prenatal color Doppler ultrasonography can evaluate its imaging features comprehensively and objectively,and has important clinical value in the diagnosis of fetal ductus arteriosus stenosis.
