Evaluation of Foetal Doppler After Maternal Covid-19 Disease: How Does Foetal Aortic Isthmus Doppler Change?

Abstract

Objective: We aim to evaluate the foetal aortic isthmus Doppler data after maternal COVID-19 disease. Material and Methods: Twenty six pregnant patient who recovered from COVID-19 and 43mhealthy patient were included in this prospective case–control study. The study group consisted of those who had COVID-19 disease and completed the quarantine period. Results: Doppler ultrasound evaluations were performed at the similar gestational week. We observed significantly high pulsatility indices (PI) of umbilical and aortic isthmus in study group than the control group (p=0,02, p=0,02). There was no significant change in cerebroplacental ratio (CPR) between the two groups (p>0.05). Conclusion: COVID-19 may affect placental function in pregnant women and could deterioration on foetal circulation and Doppler parameters. In particular, changes in aortic isthmus doppler flow indicating foetal circulation and cerebral oxygenation help to reflect the foetal effects of COVID-19.
