P21.06: Ductus venosus Doppler flow velocity after transplacental and non‐transplasental amniocentesis during midtrimester

Abstract

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. 27 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 wave forms. 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. P21.06: Table 1.
