ASE statement to maintain the best practice for fetal echocardiogra-phy and fetal and perinatal cardiovascular care across disciplines. The purpose of this document is to provide updated recommenda-tions for the performance and interpretation of fetal echocardiogra-phy in the detection, classification, risk assessment, and perinatal
Fetal biometry and wellbeing Recommendations • The biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) can be measured routinely for the assessment of fetal size (GOOD PRACTICE POINT). • If the fetus has not been dated previously, HC or HC plus FL can be used for dating after 14weeks (GRADE
Fetal growth restriction update · Stage-based management protocol · Constitutional small-for-gestational age · Early-severe versus late-mild fetal growth restriction. Abstract. Small fetuses are defined as those with an ultrasound esti-mated weight below a threshold, most commonly the 10th centile.
ISUOG GUIDELINES. Who should perform the first-trimester fetal ultrasound scan? Individuals who perform obstetric scans routinely should have specialized training that is appropriate to the practice of diagnostic ultrasound for pregnant women. (GOOD PRACTICE POINT)
Performing a routine first-trimester ultrasound exami-nation at 11 0 to 14. 0 weeks’ gestation is of value for confirming viability and plurality, accurate preg-nancy dating, screening for aneuploidies, identification of major structural anomalies and screening for preterm pre-eclampsia.
Introduction. Effective prediction of preeclampsia (PE) can be achieved at 11–13 weeks’ gestation by a combination of maternal characteristics, mean arterial pressure (MAP), uterine artery pulsatility index, maternal serum placental growth factor and pregnancy-associated plasma protein-A [1] .
BASIC PRINCIPLES. Ultrasound images of flow, whether color flow or spectral Doppler, are essentially obtained from measurements of movement. In ultrasound scanners, a series of pulses is transmitted to detect movement of blood. Echoes from stationary tissue are the same from pulse to pulse.
