摘要
应用彩色多普勒血流显像检测胎儿血流发现正常中晚孕胎盘胎儿各血管S/D比值有一定规律性。子宫胎盘动脉、胎儿降主动脉和颈内动脉S/D维持稳定,脐动脉S/D与孕龄呈负性相关,方程y=5.51-0.09x,r=-0.91。妊高征等病理组S/d异常出现率明显高于正常组,且发现其对病程的发展、围产结果有预报价值。方法简单,可靠。
CDFI was used to measure blood now In normal pregnancy. The relationship between arterial blood flow and gestational age Is regularity Indices of uteroplacental artery. fetal aortlc artery and Internalcarotld artery bfootl velocity remmn stable to term. A slgnlflcant negative correlatmn hs hen Oherved bet、en umbbilical arterysy。tolic/dlastollc ratio(s/d) and Preg’lanCy ay, and:。 desctikd the equation y=5.51一0.09x。 S/D ratio were signiflcantly higher in pregnancyindyed hypertension than in normal.It is therefore a useful means of predicting the incidence of complication and prenatal result.
