Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In developing countries including Egypt, low birth weight is a national concern and emphasized in population and health policies according to the latest WHO data published in April 2011 low Birth Weight Deaths in Egypt reached 13,587 or 3.74% of total deaths, Mortality was more frequent in LBW (31.6%) than normal birth weight (NBW) infants (2.0%).
Fetal growth restriction (FGR) is defined as fetuses whose growth velocity slows down or stops completely because of inadequate oxygen and nutritional supply or utilization (Linda; Murray 2010). Low birth weight (LBW) refers to an infant with a birth weight \< 2500 g, Small for gestational age (SGA) birth is defined as an estimated fetal weight (EFW) less than the 10th centile and severe SGA as an EFW less than the 3rd centile, (RCOG Green-top Guideline No.31, 2013).
Ultrasound has been used as a tool for determining fetal health and a variety of sonographic parameters have been used to screen and diagnose IUGR including fetal biometry, fetal body proportions (Campbell et al., 1994), amniotic fluid volume (Owen et al., 1999), subcutaneous tissue thickness and estimated fetal weight (EFW) (Larciprete et al., 2005).
IUGR is associated with changes in the body proportions as undernourished fetus directs most of its energy to maintain the growth of vital organs, such as the brain and heart, at the expense of the liver, muscle and fat and this results in decreased abdominal and thigh circumference measurements and hence theoretically increased HC/AC, FL/AC and FL/TC ratios (Colley et al., 1991).
Fetal thigh circumference has a role to play in accurately measuring fetal weight when incorporated with other fetal parameters and provide a potentially straightforward method for assessing the deposition of muscle and fat in the growing fetus; there is a scope of using the FL/TC ratio in predicting IUGR (Sanyal et al., 2012).
Fetal thigh circumference to femur length ratio (FL/TC) seems to be potential for use in predicting IUGR (Shripad; Varalaxmi, 2005).
