OP08.06: Fetal hemodynamic change after aspiration/thoraco‐amniotic shunting for fetal hydrothorax: conventional Doppler and ultrasonic phased‐tracking study.

This article, titled "Fetal hemodynamic change after aspiration/thoraco-amniotic shunting for fetal hydrothorax: conventional Doppler and ultrasonic phased-tracking study," examines the effects of fetal therapies for hydrothorax on fetal hemodynamics. The study analyzes measurements such as pulse wave velocity (PWV) and estimated pulse pressure (ePP) using the ultrasonic phased-tracking method (PTM). The results show that PWV and ePP decreased after aspiration of effusion (ASP) and thoraco-amniotic shunting (TAS), indicating a decrease in fetal blood pressure. The study suggests that hypovolemia caused by rapid drainage of effusion may be the main factor for the decrease in PWV and ePP. [Extracted from the article]
