Abstract
Objective Application of detection of fetal umbilical artery blood stream by ultrasound test was measured the main reason of increased fetal umbilical artery blood stream S/D ratio, and the relationship between the increased fetal umbilical artery blood stream S/D ratio and the outcome of pregnancy. Methods 157 cases with increased S/D ratio were selected as cases and 120 cases with common S/D ratio were selected as controls, the reason of increased S/D ratio and compared the two pregnant outcome in the two groups was analyzed. Results (T) A-mong 157 cases with increased S/D ratio, 60 cases were due to hypertension syndrome of pregnancy, 30 cases were cord around neck, 18 cases were intrahepatic cholestasis of pregnancy ( ICP ), 17 cases were oligohydramnios, 13 cases were diabetes, 11 cases were postponed pregnancy, 8 cases were twin pregnancy, 5 cases were placenta pre-via and 5 cases were fetal anomaly; (2) The results indicated that incidence of the fetal distress, neonatal asphyxia, low birth weight infant, fetal abnormalities and perinatal infant mortality of cases was significantly higher than controls ( P <0. 05 ); (3) 9 cases were absent end - diastolic flow velocity ( AEDV ), and 3 cases combine with the severe preeclampsia. 2 cases were FGR, 2 cases were twin transfusion syndrome, 1 case was chromosomal abnormality, 7 cases were perinatal death. Conclusion Many complications and fetal abnormalities should cause the increase of S/D ratio. The fetal umbilical artery blood stream abnormality correlate with poor pregnant prognosis. To monitor the change of S/D has high value in predicting the pregnant abnormalities, and to enhance the detection during pregnancy and terminating pregnancy properly could improve the prognosis of mother and child for high risk factors existed.
