Abstract
Whether early SARS-CoV-2 definitively increases the risk of stillbirth is unknown, though studies have suggested possible trends of stillbirth increase during the pandemic. This study of third trimester stillbirth does not identify an increase in rates during the first wave of the pandemic period, however investigation of the placental pathology demonstrates trends towards more vascular placental abnormalities.
摘要
虽然有研究表明，在大流行期间可能存在死产增加的趋势，但目前尚不清楚早期的 SARS-CoV-2 是否会明确增加死产的风险。本研究中并未发现第三孕期死产率在大流行期间第一波疫情时增加，但胎盘病理检查结果表明，胎盘血管异常的趋势更为明显。
