摘要
目的应用彩色多普勒超声,研究脐动脉舒张末期血流缺失的产生因素与围产儿结局的关系.方法对17例出现舒张末期血流缺失母儿应用彩色多普勒技术对脐动脉血流频谱进行血流动力学分析,并与未发生舒张末期血流缺失的459例(对照组)进行比较.结果 (1)舒张末期血流缺失组17例中,形态异常6例(35.29%);(2)双胎1例(5.88%),为双胎输血综合征,体重差异20.8%,发生围产儿死亡;(3)舒张末期血流缺失组妊娠高血压综合征,羊水过多、过少,胎儿宫内发育迟缓,胎儿窘迫,糖尿病,前置胎盘围产儿死亡的发生率明显高于对照组.结论胎儿脐血流检测中,出现舒张末期血流缺失的改变是母体-胎盘,胎儿-胎盘循环障碍的表现,提示胎儿预后不良,临床应给予高度重视.
Objective To research the related factors of umbilical artery end diastolic blood stream flaw and its relation with the outcome of perinatal baby by colored Doppler ultrasound.Methods We used the colored Doppler technology to analyze the blood stream dynamics of umbilical artery blood stream frequency spectrum.We also analyzed the clinical data of 17 cases of end-diastolic blood stream flaw,and compared with 459 cases without end-diastolic blood stream flaw（control group）.Results（1）In 17 cases of end-diastolic blood stream flaw,6 cases had abnormal shape of umbilical artery,accounted for 35.29%;（2）1 case had twins,accounted for 5.88%,and was diagnosed as twin to twin transfusion syndrome,the body weight difference was 20.8%,and perinatal death occurred.（3）The incidence of pregnancy-induced hypertension syndrome,polyhydramnios,oligohydramnios,intrauterine growth retardation,fetal distress,diabetes,placenta previa,and perinatal death in end-diastolic blood stream flaw group is significantly higher than that in control group.Conclusion In the embryo umbilical artery blood stream examination,end-diastolic blood stream flaw is the indicator of uterine placenta and embryo-placenta circulation barrier,which suggest poor prognosis of embryo,and should be paid attention.
