摘要 目的:应用M型彩色多普勒超声心动图探讨脐带绕颈胎儿右心室舒张早期血流传播速度(Propagation velocity,Vp)的变化以及Vp在评价脐带绕颈胎儿心室舒张功能的临床价值。方法:实验组为孕22~38周脐带绕颈的胎儿60例;对照组为孕22~38周无脐带绕颈的正常胎儿60例,彩色M型超声心动图测定胎儿右心室舒张早期Vp变化。结果:Vp在实验组与对照组间有显著差异(P<0.05),脐带绕颈胎儿右心室的Vp显著低于对照组,表明脐带绕颈胎儿右心室舒张功能减低;不同孕周脐带绕颈胎儿右心室的Vp无显著差异(P>0.05),表明脐带绕颈胎儿右心室舒张功能随孕周无明显变化。结论:脐带绕颈胎儿右心室Vp值低于正常胎儿,表明脐带绕颈胎儿右心室舒张功能减低;不同孕周脐带绕颈胎儿右心室Vp值没有明显差异,表明脐带绕颈胎儿右心室舒张功能与孕周没有相关性;彩色M型超声心动图测得的Vp能够较好的反映胎儿右心室舒张功能变化,能够为评价脐带绕颈胎儿心室舒张功能情况提供有价值的参考。

AbstractObjective: To investigate the diastolic function of right ventricle of fetuses with umbilical cord around neck, and to analyze the changes of propagation velocity(Vp) of the right ventricle, then to discuss the clinical value of color M-mode echocardiography in quantitatively evaluating ventricular diastolic function in fetuses. Methods: The experimental group consisted of fetuses with umbilical cord around neck in 22 to 38 weeks of gestational age, including 60 cases; The control group consisted of normal fetuses without umbilical cord around neck in 22 to 38 weeks of gestational age, including 60 cases. And analyze the changes of Vp of the right ventricle by color M-mode echocardiography. Results: The Vp of right ventricular showed significantly different between the experimental group and control group(P<0.05), Vp of the right ventricle in fetuses with umbilical cord around neck was significantly lower than the control group, indicating that right ventricular diastolic function reduced in fetuses with umbilical cord around neck. Vp of right ventricular has no significant difference in different gestational fetuses with umbilical cord around neck(P>0.05), indicating that right ventricular diastolic function has no significant changes with gestational age increasing in fetuses with umbilical cord around neck. Conclusion: Vp of the right ventricle in fetuses with umbilical cord around neck was significantly lower than the control group, indicating that right ventricular diastolic function reduced in fetuses with umbilical cord around neck. Vp of right ventricular has no significant difference in different gestational fetuses with umbilical cord around neck(P>0.05), indicating that right ventricular diastolic function has no significant changes with gestational age increasing in fetuses with umbilical cord around neck. Vp measured by color M-mode echocardiography can better reflect the changes of right ventricular diastolic function in fetuses, which was able to provide valuable reference about the ventricular diastolic function in fetuses with umbilical cord around neck.
