Evaluation of 3D power Doppler in Comparison to 2D Color Doppler in IUGR

Abstract

The main objective of the modern antenatal programs is to identify high risk pregnancies then to predict the possibility of adverse pregnancy outcome as early as possible. FGR is Considered by the American College of Obstetricians and Gynecologists “the most common and complex problem in modern obstetrics”. The introduction 3D power Doppler ultrasonography provides new insights into placental pathophysiology with this technique it is possible to investigate blood flow in placental volume samples and directly estimate placental perfusion. Our study was performed between November 2014 and May 2016 including 74 pregnant women gathered from outpatient clinic at Ain Shams University, in a form of a prospective observational study that aimed to investigate the role of 3D power Doppler ultrasonography in the assessment of FGR with various degrees of severity and onset, and compare the results with conventional analysis of 2D Doppler. Our results showed that 3D Power Doppler parameters were significant in prediction of poor neonatal outcome regarding development of respiratory complications, neurological complications and IUFD as complications to IUGR comparing to 2D color Doppler parameters which were non significant in these cases. Our results also showed that the only parameter of 2D Color Doppler that showed significance and positive correlation to birth weight among these cases was Middle Cerebral Artery Pulsitility Index.
