【摘要】 目的本实验主要研究胎儿静脉导管(DV)血流量与脐静脉(UV)血流量比与围产儿预后的关系。方法通过彩色多普勒超声检测晚期妊娠胎儿的DV与UV的血流参数,分别储存图像、记录数据并计算静脉导管血流量与脐静脉血流量比,进行统计学分析。结果围产儿不良结局时静脉导管的血流量与脐静脉血流量比(DVQ/UVQ)显著增加。结论静脉导管与脐静脉血流参数可作为判断围产儿预后的一项重要指标,对指导围产医学具有一定的临床价值。更多还原

【Abstract】 Objective To study the correlation between perinatal fetal prognosis and flow ratio of ductus venosus to umbilical vein (DV/UV).Methods The indices of DV and UV blood flow were obtained on color Doppler flow Imaging (CDFI)and the flow ratio of DV/UV were computed and statistically analysed.Results (1)After 12 week gestational age,the average diameter of UV was 2 mm.The Doppler spectrum of DV was triphasic in the nomal group but the systolic atrial wave (a wave) showed reverse blood flow in the abnormal group.(2)The ratio of DVQ to UVQ(DVQ/UVQ)was significantly different between the normal and abnormal groups.Conclusions The ratio of DVQ to UVQ can be used as an index for judging early fetal prognosis.更多还原
