Dopller of fetal weight with the use of head, body and femur measurements a prospective study. Pathology In a non-gravid state and at the very start of pregnancy the flow in the uterine artery is of high pulsatility with a high systolic flow and low diastolic flow. FGR should be diagnosed in the presence of any of the factors associated with a poorer perinatal outcome, including Doppler cerebroplacental ratio, uterine artery Doppler, a growth centile below the 3rd centile, and, possibly in the near future, maternal angiogenic factors.
Whenever possible, and after obtaining the mother’s informed consent see Appendixcord blood was collected and tested for lipid markers cholesterol and triglyceride and cardiovascular dysfunction markers N-terminal pro b-type natriuretic peptide [NT-proBNP], cardiac troponin T [cTnT] and heart-type fatty acid binding protein [hFABP].
