Reduction of moderate cerebral artery indices in IUGR pregnancy. Of pregnancy with IUGR, the mean amniotic fluid level is substantially reduced. A prospective study was conducted at the KIMS for routine prenatal screening with 50 females with natural singleton pregnancy and 50 females with intrauterine development are pregnant. Study duration was from Oct. 2011 to May 2013. The study aims to evaluate the velocity of the blood flow of the brain and umbilical artery in normal and growth-restricted pregnancy. IUGR pregnancy significantly increases the umbilical artery index. The umbilical cerebro ratio in the research group is substantially decreased, indicating the possibility of brain sparing impact.
