To investigate the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on fetal Doppler parameters.
This was a prospective case-control study conducted in Ankara City Hospital with confirmed SARS-CoV-2 infected pregnants between August 1, 2020 and October 1, 2020. There were 54 COVID-19 confirmed pregnant women and 97 age-matched pregnant women as a control group between 28 and 39 weeks. Infection was confirmed based on positive real-time polymerase-chain reaction results. Demographic features, uterine artery (right, left), umblical artery, middle cerebral artery, ductus venosus, cerebro-placental ratio, and cerebral-placental-uterine ratio Doppler parameters were investigated in both groups.
Two groups were similar in terms of demographic features and no difference was found for fetal Doppler parameters.
COVID-19 seems to have no adverse effect on fetoplacental circulation in mild and moderate patients during the acute phase of the infection.
Special thanks to all the perinatology division staff who work with devotion for the treatment of high-risk pregnancy patients during the pandemic period.
