Abstract
Evaluation of 3D power Doppler in Comparison to 2D Color Doppler in IUGR
Abstract
Intrauterine growth restriction (IUGR) was defined as an ultrasound-estimated fetal weight below the 10th centile (P10) for gestational age according to the Hadlock 4 equation for fetal weight estimation using biparietal diameter, head circumference, abdominal circumference and femur length. The entity of fetal growth restriction (FGR) remains challenging and complex in modern obstetrics. Fetal IUGR associated with placental insufficiency can present well recognized perinatal and long term consequences. In FGR with mild placental dysfunction, isolated decrease in Doppler indices of the middle cerebral artery (MCA) without any change in the UA Doppler indices were described. Power Doppler sonography uses the amplitude component of the signals received to represent the number of moving blood cells. The aim of the present study is 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 study was including 74 pregnant women gathered from outpatient clinic, 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.
