The gross perinatal mortality rate in the present study was 16.2%, but during the last 5\u2010year period the incidence of UCP (0.09%) as well as the perinatal mortality rate (5.9%) declined significantly. UCP seemed to be more prevalent during the first half of the year. The most prominent precipitating factors for the occurrence of UCP seemed to be abnormal presentation, multiple pregnancy, low birth weight, and multiparity. Amnio\u2010tomy seemed not to increase the risk for UCP. Diminished perinatal mortality figures were closely associated with increased cesarean section rates in the management of deliveries complicated by UCP. Cesarean section is therefore recommended as the treatment of choice for deliveries complicated by UCP.<\/jats:p>","DOI":"10.3109\/00016348509156364","type":"journal-article","created":{"date-parts":[[2009,12,8]],"date-time":"2009-12-08T17:57:28Z","timestamp":1260295048000},"page":"567-570","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["PREDISPOSING AND RISK FACTORS OF UMBILICAL CORD PROLAPSE"],"prefix":"10.1111","volume":"64","author":[{"given":"Ari","family":"Yl\u00e4\u2010Outinen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pentti K.","family":"Heinonen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Risto","family":"Tuimala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,1,11]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(74)90496-7"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016347209156863"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(15)33513-4"},{"key":"e_1_2_1_5_1","first-page":"1060","article-title":"Sono\u2010graphic demonstration of occult umbilical cord prolapse","volume":"134","author":"Donelly P B.","year":"1980","journal-title":"Am J Radiol"},{"key":"e_1_2_1_6_1","doi-asserted-by":"crossref","first-page":"52","DOI":"10.1016\/0002-9378(51)91090-3","article-title":"Prolapse of the cord during labour","volume":"62","author":"Fenton A N.","year":"1951","journal-title":"Am J Obstet Gynecol"},{"key":"e_1_2_1_7_1","first-page":"1","volume":"136","author":"Jalkanen R.","year":"1953","journal-title":"Gynecologia"},{"key":"e_1_2_1_8_1","first-page":"84","article-title":"\u00dcber die Nabelschnurvorf\u00e4lle in der St\u00e4dtichen Entbindings\u2010anstalt Tampere w\u00e4hrend der J\u00e4hre 1941\u201355","volume":"46","author":"Niemineva K.","year":"1957","journal-title":"Ann Chir Gynecol Fennae"},{"key":"e_1_2_1_9_1","first-page":"951","volume-title":"In Principles and Practise of Obstetrics and Perinatology","author":"Pelosi M A.","year":"1981"},{"key":"e_1_2_1_10_1","first-page":"502","article-title":"Prolapse of the umbilical cord","volume":"36","author":"Savage E W.","year":"1970","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_11_1","first-page":"159","article-title":"The association of umbilical cord complications and variable deceleration with acid\u2010base findings","volume":"49","author":"Tejani N A.","year":"1977","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_12_1","first-page":"962","article-title":"Prolapse of the umbilical cord: a method of management","volume":"107","author":"Vago T.","year":"1978","journal-title":"Am J Obstet Gynecol"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016346309157865"}],"container-title":["Acta Obstetricia et Gynecologica Scandinavica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.3109%2F00016348509156364","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.3109\/00016348509156364","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T20:36:11Z","timestamp":1697834171000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.3109\/00016348509156364"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1985,1]]},"references-count":12,"journal-issue":{"issue":"7","published-print":{"date-parts":[[1985,1]]}},"alternative-id":["10.3109\/00016348509156364"],"URL":"https:\/\/doi.org\/10.3109\/00016348509156364","archive":["Portico"],"relation":{},"ISSN":["0001-6349","1600-0412"],"issn-type":[{"value":"0001-6349","type":"print"},{"value":"1600-0412","type":"electronic"}],"subject":[],"published":{"date-parts":[[1985,1]]},"assertion":[{"value":"2011-01-11","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
