Abstract

Abstract: We aimed to examine the contribution of splenic artery (SA) Doppler parameters in the detection of foetuses with late-onset foetal growth restriction (LO-FGR) and to evaluate its power in predicting adverse perinatal outcomes. Within the study's scope, 52 cases in the LO-FGR group and 92 cases in the control group were evaluated. The criteria determined in the Delphi procedure by an international consensus were used to define the LO-FGR. Middle cerebral artery (MCA) pulsatility index (PI) and SA PI were significantly lower in the LO-FGR group ( p : .002, p <.001, respectively). Likewise, cerebroplacental ratio (CPR) was significantly lower in the LO-FGR group ( p <.001). Decreased CPR and decreased SA PI were significantly and positively associated with an increased likelihood of exhibiting adverse obstetric outcome ( p <.001, p : .012, respectively). The receiver operating characteristic (ROC) curve analysis showed that the optimal cut-off value for SA PI was 1.41 to predict LO-FGR with 70.7% sensitivity and 61.5% specificity (AUC = 0.684; 95% CI, 0.594–0.774). Impact Statement: What is already known on this subject? The main clinical difficulty in late-onset foetal growth restriction (LO-FGR) is the detection of the disease. What do the results of this study add? The splenic artery (SA) pulsatility index (PI) may contribute to both diagnostic and the prediction of adverse perinatal outcomes in LO-FGR cases. Our results showed that the SA PI value, as well as cerebroplacental ratio (CPR), can be a useful parameter in predicting negative outcomes. What are the implications of these findings for clinical practice and /or further research? Various degrees of uteroplacental insufficiency in foetuses with LO-FGR may be associated with abnormalities in SA Doppler velocimetry. Splenic artery Doppler velocimetry can be used for the clinical management of LO-FGR.
