Abdominal ultrasound at the hospital showed no fetal movements, and cardiotocography (CTG) was pathological. All women delivered via cesarean section within 24 hours after admission. Placental pathology in all cases showed massive perivillous fibrin deposition and extensive histiocytic intervillositis. All placentas were Covid-19 polymerase chain reaction (PCR) positive. The infants were Covid-19 PCR negative. Consistent with other published case reports, we hypothesize that Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can affect the placenta resulting in massive perivillous fibrin deposition and histiocytic intervillositis leading to acute placental insufficiency and fetal hypoxia. The absence of intrauterine growth restriction also augments the theory of an acute onset of placental insufficiency due to the Covid-19 infection.<\/jats:p>","DOI":"10.1155\/2023\/2018551","type":"journal-article","created":{"date-parts":[[2023,3,28]],"date-time":"2023-03-28T20:20:45Z","timestamp":1680034845000},"page":"1-8","source":"Crossref","is-referenced-by-count":2,"title":["A Case Series on Pregnant Patients with Mild Covid-19 Infection and Signs of Severe Placental Insufficiency"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3739-1725","authenticated-orcid":true,"given":"A.","family":"Ivert","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Karolinska University Hospital, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Lindblad Wollmann","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Karolinska University Hospital, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Pettersson","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Karolinska University Hospital, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"doi-asserted-by":"publisher","key":"1","DOI":"10.1001\/jamapediatrics.2021.1050"},{"doi-asserted-by":"publisher","key":"2","DOI":"10.1111\/aji.13332"},{"doi-asserted-by":"publisher","key":"3","DOI":"10.1007\/s10238-020-00648-x"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1016\/j.ajog.2017.11.577"},{"issue":"3","key":"5","doi-asserted-by":"crossref","first-page":"289.e1","DOI":"10.1016\/j.ajog.2021.05.014","article-title":"Preeclampsia and COVID-19: results from the INTERCOVID prospective longitudinal study","volume":"225","author":"A.
