摘要
目的:探究超声心动图检测在正常胎儿动脉导管血流频谱定量研究中的应用意义。方法:择取本院2012年9月-2014年9月收治的行产前超声检查并分娩的156例正常单胎为研究对象,应用彩色多普勒超声心动图,检测正常胎儿动脉导管,详细观察胎儿各个发育时期动态变化规律。结果:156例正常胎儿均获取相对清晰的动脉导管二维超声心动图与血流频谱图,动脉导管脉冲多普勒频谱呈双峰型;经由回归性分析发现,孕龄与AT、PFVd、PFVs呈正相关(P<0.05)。结论:超声心动图检测在正常胎儿动脉导管血流频谱定量研究中具有至关重要的应用意义,可提供胎儿循环系统生理信息,及早评估胎儿风险值,并及时采取干预措施,临床上应引起足够重视。
Objective:To explore the application of detection of ultrasonic beckoning diagram on blood flow spectrum of fetal ductus arteriosus. Method:To select 156 patients with normal singleton birth for prenatal ultrasonography in our hospital from September 2012 to September 2014 as the research objects,application of color doppler ultrasound beckoning diagram,detection of normal fetal ductus arteriosus,variation rules of dynamic observation of the fetal period with different development. Result:156 patients with normal fetal ductus were obtain two-dimensional ultrasound relatively clear beckoning with color Doppler flow spectrum,transcatheter arterial pulse doppler spectrum showed a bimodal pattern;through regression analysis,related to gestational age and AT,PFVd,PFVs positive(P〈0.05). Conclusion:The application of graph is of vital significance of beckoning detected in normal fetal ductus arteriosus blood flow spectrum in quantitative study of ultrasound,fetal circulation system can provide physiological information,early assessment of fetal risk value,timely intervention,clinical attention should be paid.
