Abstract:
Purpose To assess the haemodynamic change of fetus with nervous system abnormalities by using spectral Doppler ultrasound.Materials and Methods Twenty-two fetuses with nervous system abnormalities diagnosed by ultrasound examination in Beijing Obstetrics and Gynecology Hospital,Capital Medical University,September,2015 to May,2016 were chosen.Fetus gestational week was 20-24 weeks.All Fetuses with abnormalities in nervous system were confirmed by autopsy and image examination after birth.Meanwhile,50 cases of normal fetuses with same gestational week were chosen as control group.Assessment indexes of spectral Doppler ultrasound between the two groups were compared,including myocardial performance index (MPI) of left ventricle (automatic survey),middle cerebral artery (MCA),umbilical artery (UA) and heart rate.Results MPI in control group and in simple nervous system abnormal group were compared,the difference was statistical significant (0.44±0.05 vs 0.48±0.08,P＜0.05).MCA resistance index in the two groups showed statistically significant difference (0.80±0.06 vs 0.88±0.14,P＜0.05).The difference of other indexes showed no statistical significant (P＞0.05).Conclusion MPI automatic survey is reliable and convenient for assessing cardiac function of fetus.There is a certain change of haemodynamic for fetus with abnormal nervous system and normal ones,which is represented by decline of fetus cardiac function and increase of MCA resistance.Spectral Doppler ultrasound can provide more information and evidences for intrauterine monitoring of fetus with abnormal nervous system.
