Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy. IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [ 5 ]
If small for gestational age babies have been the subject of intrauterine growth restriction, formerly known as intrauterine growth retardation, [5] the term "SGA associated with intrauterine growth restriction" is used. Intrauterine growth restriction refers to a condition in which a fetus is unable to achieve its genetically determined ...
If velamentous cord insertion is diagnosed, fetal growth is assessed every four weeks using ultrasound beginning at 28 weeks. If intrauterine growth restriction is observed, the umbilical cord is also assessed for signs of compression. Non-stress tests may be performed twice a week to ensure adequate blood flow to the fetus. [16]
An impaired placenta cannot support the pregnancy and this may lead to the loss of a chromosomally normal baby. [5] On the other hand, an apparently normal diploid fetus may experience problems with growth or development due to the effects of uniparental disomy (UPD). Intrauterine growth restriction (IUGR) has been reported in a number of CPM ...
Intrauterine growth restriction may cause or be the result of hypoxia. Intrauterine hypoxia can cause cellular damage that occurs within the central nervous system (the brain and spinal cord). This results in an increased mortality rate, including an increased risk of sudden infant death syndrome (SIDS).
It can be detected in the first trimester of pregnancy with the use of 2D ultrasound. The sonographer is able to identify a 2 vessel cord in an image with the bladder and color Doppler, which will show only one artery going around one side of the bladder. In a normal fetus, there would be 2 arteries (one on each side of the bladder). [5]
Illustration of fundal height at various points during pregnancy. Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth. They may include aneuploidies, structural abnormalities, or neoplasms. Acardiac twin; Achondrogenesis; Achondroplasia
