Single centre study which included non-anomalous singleton pregnancies complicated by late-onset FGR, as defined either by abdominal circumference (AC) or estimated fetal weigth (EFW) below the 10th percentile for the gestation or by a reduction of the longitudinal growth of the AC. Abnormal Doppler was defined either by CPR <5th centile or UA PI > 95th percentile or by mean UtA PI > 95th percentile for the gestation. Abnormalities in the maternal and fetal Doppler are associated with low gestational age at delivery and low birthweight, however the gestational age at delivery seems to be the strongest independent predictor of adverse perinatal outcomes in late-onset FGR.

To assess the impact of the cervical sliding sign (CSS) in case of threatened preterm labour (TPL). In case of threatened preterm labour, the CSS seems associated with a higher risk of preterm delivery in the subgroup of patients with CL 10-20mm. [Extracted from the article]

The HC/MH ratio proved to be independently associated with CS due to intrapartum dystocia (p < 0.01) at logistic regression analysis; the AUC of the HC/MH ratio for CS due to labour dystocia was 0.742, 95%CI (0.666-0.819), p < 0.01. To evaluate the relationship between the fetal head circumference (HC) to maternal height (MH) ratio (HC/MH ratio) MH ratio measured close to delivery and the occurrence of Caesarean section (CS) for labour dystocia. Conclusions Data on a wide cohort of unselected pregnancies showed a fair accuracy of the HC/MH ratio in the prediction of labour dystocia leading to CS. [Extracted from the article]

The projection of the EFW at the time of delivery was performed by using Yudkin's chart percentiles and the gestation-adjusted projection (GAP) method. A significant correlation between the EFW percentile and the birthweight percentile was found both for the 2D-US-EFW centile (0.654, r SP 2 sp 0.430, p <0.001) and the 3D-US-EFW centile (0.678, r SP 2 sp 0.460, p <0.001) as well as for the 2D-US-EFW-GAP and the 3D-US-EFW-GAP (0.600, r SP 2 sp 0.360, p <0.001 and 0.629, r SP 2 sp 0.396, p <0.001, respectively). Similarly, a non-significant difference in the accuracy of the prediction of birthweight > 4000 grams (AUC 0.788, 95% CI 0.716-0.859 for 2D-US-EFW vs AUC 0.802, 95% CI 0.723-0.880 for 3D-US-EFW, p 0.72) and > 4500 grams (0.828, 95% IC 0.720-0.936 for 2D-US-EFW vs 0.858, 95% IC 0.759-0.956 for 3D-US-EFW, p 0.71) with the GAP method could be demonstrated.

To evaluate the relationship between uterine artery (UtA) Doppler measured in early labour, cerebroplacental ratio (CPR) and perinatal outcomes in a cohort of uncomplicated singleton term pregnancies. Umbilical artery (UA), middle cerebral artery (MCA) and UtA pulsatility index (PI) were measured on admission for early labour. Data on a wide cohort of low-risk term pregnancies in early labour have shown that an increased UtA PI MoM is inversely correlated to CPR MoM but not associated with any of the considered adverse perinatal outcomes.

EP23.18: The chin-chest angle (CCA): a new objective method to assess the degree of fetal head deflexion in occiput-posterior fetuses To test the chin-chest angle (CCA) as a new ultrasound (US) quantitative marker of fetal head deflexion in persistent occiput-posterior (OP) presentation. Quantitative assessment of fetal head deflexion in OP fetuses is feasible by the ultrasound measurement of CCA. [Extracted from the article]
