We aimed to evaluate ductus venosus Doppler waveforms before and after amniocentesis in order to investigate any effect of amniocentesis on fetal myocardial hemodynamics. We also evaluated the umbilical artery, uterine artery and fetal mid-cerebral artery Doppler waveforms in order to investigate any relationship with ductus venosus Doppler changes.
The study population consisted of 56 singleton pregnancies having genetic amniocentesis. Twenty seven of them had transplacental needle insertion; whereas 29 of them had non-transplacental amniocentesis. Uterine artery, umbilical artery, mid-cerebral artery and ductus venosus pulsatiliy index and resistance index were measured just before and after amniocentesis.
Amniocentesis does not cause any significant changes in fetal ductus venosus Doppler waveforms. There is also no significant changes in uterine artery, umbilical artery, mid-cerebral artery pulsatility and resistance index.
Amniocentesis-whether transplacental or not- does not cause any significant effect on fetal myocardial hemodynamics.
评估羊膜穿刺术前后的静脉导管多普勒波形，以研究羊膜穿刺术对胎儿心肌血液动力学的任何影响。我们还评估了脐动脉、子宫动脉和胎儿大脑中动脉的多普勒波形，以研究与静脉导管多普勒变化的任何关系。
研究人群包括 56 例单胎妊娠进行遗传羊膜穿刺术。其中 27 例经胎盘针插入；而 29 例为非胎盘羊膜穿刺术。在羊膜穿刺术前后测量子宫动脉、脐动脉、大脑中动脉和静脉导管搏动指数和阻力指数。
羊膜穿刺术不会引起胎儿静脉导管多普勒波形的任何显著变化。子宫动脉、脐动脉、大脑中动脉搏动和阻力指数也没有明显变化。
无论胎盘内还是胎盘外的羊膜穿刺术都不会对胎儿心肌血液动力学产生显著影响。
