He adds that combining this new approach with the uterine artery Doppler pulsatility index increased the overall accuracy of the prediction.
In these cases, ductus venousus and pulsatility index of the middle cerebral artery Doppler are used for prediction.
The uterine artery Doppler pulsatility index (PI) was studied in 20 studies (in 14 as the sole ultrasonographic marker and in 6 as a component of a suite of ultrasonographic markers).
The patient-specific risk of developing pre-eclampsia can be predicted by a combination of factors in the maternal history, and measurements of the maternal blood pressure, Doppler assessment of the uterine artery pulsatility index (PI) (1st and 2nd trimesters), and maternal serum level of PAPP-A, PLGF and PP13 ( 1st trimester).
Fetal growth restriction was defined by a combination of abdominal circumference below the 5th percentile and more than a 2-standard-deviation elevation of the umbilical artery pulsatility index.
A pulsed-Doppler apparatus (Acuson 128SP5) was used for blood flow velocity measurement of the middle cerebral artery pulsatility index (MCA PI), performed at the same time that blood was drawn.
Peripheral perfusion and oxygenation assessment using near-infrared spectroscopy (NIRS) and the oximeter pulsatility index in healthy neonates.
The small fetuses were classified as FGR due to placental dysfunction (umbilical artery Doppler, growth velocity pulsatility index > 2 SD for gestational age) or normal small (normal Doppler, growth velocity and amniotic fluid volume).
