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 ]
In patients diagnosed with circumvallate placenta during pregnancy, monthly fetal growth assessments are also recommended. Patients found to have blood flow restrictions to or from the placenta are recommended to undergo weekly ultrasounds with consistent monitoring of fetal heart rate. [3]
The 80% of MoDi pregnancies without TTTS still have high rates of birth weight discordance, fetal growth restriction, prematurity and resultant cesarean section deliveries. [1] One twin may also fail to develop a proper heart and become dependent on the pumping activity of the other twin's heart, resulting in twin reversed arterial perfusion. [2]
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 ...
Intrauterine hypoxia (also known as fetal hypoxia) occurs when the fetus is deprived of an adequate supply of oxygen. It may be due to a variety of reasons such as prolapse or occlusion of the umbilical cord , placental infarction , maternal diabetes (prepregnancy or gestational diabetes ) [ 1 ] and maternal smoking .
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes P05-P08 within Chapter XVI: Certain conditions originating in the perinatal period should be included in this category.
Many factors, including maternal, placental, and fetal factors, contribute to the cause of impaired fetal growth. [23] There are several maternal factors, which include age, nutritional status, alcohol use, smoking, and medical conditions. [23] Insufficient uteroplacental perfusion is an example of a placental factor. [23]
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]
