Abstract Purpose Ductus venosus (DV) Doppler velocimetry reflects fetal cardiac function. Gestational diabetes mellitus (GDM) is assumed to impair cardiac function due to fetal hyperglycemia. The purpose of this study was to assess the ability of DV Doppler to predict an adverse perinatal outcome (APO) in term pregnancies with GDM. Methods This is a retrospective cohort study including GDM pregnancies of singleton, non-anomalous fetuses without any signs of placental dysfunction. All GDM women who primarily had a vaginal delivery attempt and in which DV Doppler was examined from 37+0 weeks on were included. Receiver operating characteristic curve (ROC) analyses were performed to assess the predictive value of DV pulsatility index (DV-PI) regarding a composite APO (CAPO). Furthermore, a subgroup analysis was performed regarding the presence of a large-for-gestational-age (LGA) newborn. Results A total of n=89 cases were included. Overall, CAPO occurred in 26 out of 89 cases (29.2%). All DV Doppler examinations showed a positive A wave. DV-PI was>95th percentile in 8 out of 89 cases (9%). Overall, ROC analysis showed no significant association of DV-PI with CAPO (AUC=0.523, p=0.735). However, regarding individual APO parameters, ROC analysis showed a significant association of DV-PI with 5th-min AGPAR (AUC=0.960, p=0.027), which was not confirmed after exclusion of LGA cases. Conclusion In GDM pregnancies at term, DV Doppler sonography seems to have no benefit for APO prediction.
