Mass-forming fetal anomalies feature placental histological lesions of shallow placental implantation, diffuse chronic hypoxic patterns of placental injury, and lesions of fetal vascular malperfusion, likely stasis-induced.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1093526619852869","type":"journal-article","created":{"date-parts":[[2019,5,29]],"date-time":"2019-05-29T01:36:56Z","timestamp":1559093816000},"page":"513-522","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Patterns of Placental Injury in Congenital Anomalies in Second Half of Pregnancy"],"prefix":"10.1177","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6602-2638","authenticated-orcid":false,"given":"Jerzy","family":"Stanek","sequence":"first","affiliation":[{"name":"Division of Pathology, Cincinnati Children\u2019s Hospital Medical Center, Cincinnati, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,5,28]]},"reference":[{"key":"bibr1-1093526619852869","unstructured":"Naeye RL.
