Cerebroplacental ratio and aortic isthmus systolic index in evaluation on pregnancy outcome of late-onset fetal growth restriction / 中国介入影像与治疗学

ABSTRACT

Objective: To explore the value of cerebroplacental ratio (CPR) and aortic isthmus systolic index (ISI) in evaluation on pregnancy outcome of late-onset fetal growth restriction (FGR). Methods: Totally 88 pregnant women with clinically confirmed late-onset FGR were retrospectively analyzed, among them 39 had poor pregnancy outcomes (case group) and 49 had good pregnancy outcomes (control group). CPR and ISI of fetuses were compared between 2 groups. ROC curve was used to analyze the value of CPR and ISI in predicting fetal pregnancy outcomes. Results: CPR and ISI of case group were lower than those of control group (both P<0.01). ROC curve results showed that taken 1.25 as the cut-off value of CPR, the sensitivity and specificity of adverse pregnancy outcome was 82.1% and 59.7%, respectively, and AUC was 0.814; while taken -0.44 as the cut-off value of CPR, the sensitivity, specificity and AUC was 94.9%, 82.7% and 0.930, respectively. Conclusion: Both CPR and ISI had predictive value for fetal adverse pregnancy outcome of late-onset FGR, and ISI was superior to CPR.
