Abstract
Objective To explore the rule of hemodynamics of ductus venosus (DV) in normal fetuses during second and third trimester and establish reference ranges of normal value.Methods A total of 212 cases of normal single pregnancy at 21 ～ 42 weeks'gestation admitted between January 2012 and May 2013 at Shengjing Hospital of China Medical University (121 cases) and Shenyang Women's and Children's Hospital (91 cases) were examined by color Doppler ultrasound.Among them,196 cases of flow spectrum of DV were gained successfully.The blood flow velocity parameters and resistance parameters of DV were measured.Results The ranges of normal value of every DV parameter were gained.The blood flow velocity parameters had positive correlation with gestational age (P ＜ 0.01).The resistance parameters had negative correlation with gestational ages (P ＜ 0.01).Conclusion The blood flow velocity parameters of DV in normal fetuses during second and third trimester increase with advancing gestational age,while resistance parameters decrease with advancing gestational age.关键词
