Abstract
The primary aim of this study was to investigate the potential impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on maternal and foetal Doppler findings. Doppler ultrasound findings were compared in 40 pregnant women diagnosed with COVID-19 disease who required hospitalisation (group 1) and 30 healthy pregnant women (group 2). Maternal characteristics and birth histories were recorded. Body mass index, gestational week at birth, type of delivery, oligihydroamnios, pre-term birth (<37 weeks), low birth weight (<10 percentile), perinatal death and f1st and 5th minute Apgar scores were recorded. Birth weights and foetal biophysical profile (BPP) scores in group 1 were significantly lower than those in group 2. There was a statistically significant between-group difference in the umbilical artery pulsatility index (PI), umbilical artery resistive index (RI), middle cerebral artery (MCA) PI, MCA RI, mean uterine artery (UtA) PI, mean UtA RI and cerebroplacental ratio (CPR), the parameters used to evaluate foetal-maternal blood flow. In the pregnant group diagnosed with COVID-19 and hospitalised, all foetal-maternal Doppler indicators of foetal-maternal blood flow were impaired, and birth weights and BPP scores in these patients were statistically significantly lower than those in the healthy controls.
What is already known on this subject? Foetal and maternal vascular malperfusion characterised by decidual arteriopathy have been reported in pathologies of placentas from pregnant women with SARS-CoV-2 infection.
What the results of this study add? It was determined that COVID-19 disrupted foetal and maternal blood flow.
What the implications are of these findings for clinical practice and/or further research? Foetal biometric measurements and foetal Doppler may be useful in the follow-up of perinatal outcomes in pregnant women with COVID-19
