Fetal Aortic Pulsewave Velocity: A Novel Doppler Ultrasound Method of Measuring the Biophysical Properties of the Fetal Aorta
We are interested in determining if we can measure the blood flow in the descending aorta (large blood vessel in the abdomen) of healthy fetuses and fetuses with growth restriction. An increasing number of adult diseases (e.g. heart and blood vessel disease) are recognized as potentially associated with fetal growth and development.
Pulse wave velocity (PWV) is a measure of blood flow in blood vessels. This is routinely measured in adults, and has recently been studied in children. The purpose of our study is to see if we can develop a simple ultrasound method to measure the PWV in fetuses.
The purpose of this study is to see if we can consistently measure the blood flow patterns in the fetal descending aorta (large blood vessel in the abdomen) of 20 healthy fetuses and 20 growth restricted fetuses using standard ultrasound techniques.
