Abnormal fetal growth patterns. Ultrasonic diagnosis and management.
Diagnostic ultrasound is a useful tool in the management of high-risk pregnancies and provides valuable information about abnormal fetal growth patterns including excessive fetal size and intrauterine growth retardation. Two patterns of growth retardation can be distinguished ultrasonically. Fetuses exhibiting "reduced growth potential" type patterns have little risk of fetal distress and are readily recognized as small for gestational age at birth. Fetuses suffering from uteroplacental insufficiency frequently exhibit a pattern of biparietal growth arrest in the third trimester. These fetuses have a high risk of fetal distress and should be closely monitored with other parameters of fetal-placental function including serial estriols and oxytocin challenge tests. Utilizing conventional pediatric growth criteria, the existence of intrauterine growth retardation is often unrecognized in this latter group.
