Prevalence of abnormal umbilical arterial Doppler indices in apparently normal pregnancies in Calabar.

Intrauterine growth restriction (IUGR) may occur in the presence of normal fetal growth parameters, with resultant unanticipated perinatal morbidity and mortality. Umbilical arterial Doppler evaluation determines the fetuses susceptible to compromise by detecting IUGR early enough for successful intervention measures to be implemented. This study was aimed at determining the prevalence of abnormal umbilical arterial Doppler indices (UADI) in apparently normal pregnancies and to assess its correlation with amniotic fluid index (AFI).
