چکیده
On behalf of my two principal co-investigators, Jean-Charles Pasquier, professor in the department of Obstetrics of Sherbrooke University Hospital, and Julie Gosselin, professor in the Occupational Therapy department of Université de Montréal, I would like to thank you very sincerely for agreeing to participate in our multicentre study on the clinical significance of recording fetal aortic isthmus flow during placental circulatory insufficiency.

Correlation between prenatal velocity waveforms in the aortic isthmus and neurodevelopmental outcome between the ages of 2 and 4 years.
OBJECTIVE Experimental studies on fetal lambs have shown that during an increase in the resistance to placental flow the delivery of oxygen to the brain is preserved as long as net flow through the aortic isthmus is antegrade. Our purpose was to determine whether the same changes in aortic isthmus flow in human subjects have any impact on neurodevelopmental outcome. STUDY DESIGN Forty-four fe...
متن کاملUmbilical Blood Flow
Background. This study investigated the effects of impairment to placental flow on flow patterns through the aortic isthmus because in the fetus, this vascular segment is the link between the parallel vascular systems perfused by the left and right ventricles. Methods and Results. A progressive increase in resistance to blood flow through the placenta was created in seven exteriorized fetal lam...

The first aim of this study was to investigate the relationship between Doppler ultrasonographic parameters and biochemical markers of human fetal cardiac dysfunction and myocardial cell damage in pregnancies complicated by placental insufficiency and/or fetal growth restriction. Our second aim was to examine fetal central and peripheral hemodynamic characteristics associated with retrograde ao...
متن کاملA Computational Model of the Fetal Circulation to Quantify Blood Redistribution in Intrauterine Growth Restriction
Intrauterine growth restriction (IUGR) due to placental insufficiency is associated with blood flow redistribution in order to maintain delivery of oxygenated blood to the brain. Given that, in the fetus the aortic isthmus (AoI) is a key arterial connection between the cerebral and placental circulations, quantifying AoI blood flow has been proposed to assess this brain sparing effect in clinic...
متن کاملFetal–maternal interface impedance parallels local NADPH oxidase related superoxide production
Blood flow assessment employing Doppler techniques is a useful procedure in pregnancy evaluation, as it may predict pregnancy disorders coursing with increased uterine vascular impedance, as pre-eclampsia. While the local causes are unknown, emphasis has been put on reactive oxygen species (ROS) excessive production. As NADPH oxidase (NOX) is a ROS generator, it is hypothesized that combining D...
