Placental villi from term placentas revealed intact syncytial and cytotrophoblast elements. All term placentas presented a minimal to mild degree of villous necrosis and deposition of fibrinoid material. Placental villi from cases of prolonged pregnancy presented a moderate to severe degree of necrosis in 11 of 15 placentas and a minimal to mild degree in 4 of 15 placentas. A moderate to severe degree of fibrinoid deposition was noted in 7 of 15 placentas whilst 8 of 15 revealed a minimal to mild degree of deposition. The presence or absence of meconium was noted in the prolonged-pregnancy group and correlated with the above morphological features. Statistically, a correlation was found between prolonged pregnancy and necrosis (p &lt; 0.001), prolonged pregnancy and fibrinoid deposition (p &lt; 0.03) and between necrosis and deposition of fibrinoid (p &lt; 0.05). There was no correlation between the incidence of meconium staining and the above parameters.<\/jats:p>","DOI":"10.1159\/000300969","type":"journal-article","created":{"date-parts":[[2010,3,18]],"date-time":"2010-03-18T04:40:29Z","timestamp":1268887229000},"page":"40-48","source":"Crossref","is-referenced-by-count":15,"title":["Fine Structure of the Human Placenta in Prolonged Pregnancy Preliminary Report"],"prefix":"10.1159","author":[{"given":"James A.","family":"Thliveris","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas F.","family":"Baskett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,18]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000300969","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:43:53Z","timestamp":1777617833000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000300969"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,18]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000300969","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,18]]}}}
