Clinical value of color doppler ultrasound in prenatal diagnosis of umbilical cord entry abnormity

Objective: to study the clinical value of prenatal diagnosis of umbilical cord entry abnormity (ucea) by means of color doppler ultrasound (cdus). methods: clinical data of sixty-four cases with confirmed umbilical cord entry abnormity were reviewed and the specific ucea conditions and the outcomes of perinatal infants were analyzed. results: detection rates of marginal umbilical cord entry abnormity and velamentous umbilical cord entry abnormity by means of cdus at second trimester were 94.1% and 93.8% respecdtively much higher than 80.0% and 68.8% which were those of third trimester. discrepancy had statistical significance (p<0.05). true positive rate of prenatal diagnosis of ucea by means of cdus was 85.9% (55/64),and false negative rate was 14.1% (9/64). among sixty four patients with ucea,seventeen patients (26.6%) underwent selective caesarean delivery; twenty-six patients (35.9%) underwent emergency caesarean delivery and twenty-four patients (37.5%) had normal delivery. conclusion: prenatal diagnosis of ucea by means of cdus is intuitive and accurate. it provides an evidence for determination of the best time to diagnose ucea,and also offers a proper advice for pregnant women about delivery mode to ensure the fetus survival rate,which is clinically valuable. © 2016,professional medical publications. all rights reserved.
