However, the clinical significance of a persistently decreased S\/D ratio of umbilical cord blood has not been reported. We report eight cases of a persistently decreased S\/D ratio of umbilical cord blood, with two cases of umbilical thrombus, five cases of excessive torsion, and one case of a true cord knot. Fetuses with a persistently decreased S\/D ratio of umbilical cord blood may be at risk, and it may be an important indication of umbilical cord lesions.<\/jats:p>","DOI":"10.1177\/03000605241244763","type":"journal-article","created":{"date-parts":[[2024,4,24]],"date-time":"2024-04-24T10:51:11Z","timestamp":1713955871000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["A sustained decrease in the systolic\/diastolic ratio may be a sign of severe adverse events in the umbilical cord: a report of eight cases"],"prefix":"10.1177","volume":"52","author":[{"given":"Yan-Jing","family":"Zeng","sequence":"first","affiliation":[{"name":"The First Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China"},{"name":"Guangdong Clinical Research Academy of Chinese Medicine, Guangzhou, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Guangzhou Wei Shi Tai Hemodialysis Center, Guangzhou, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan-Fang","family":"Li","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China"},{"name":"Guangdong Clinical Research Academy of Chinese Medicine, Guangzhou, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8175-2842","authenticated-orcid":false,"given":"Yu-Yi","family":"Chen","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China"},{"name":"Guangdong Clinical Research Academy of Chinese Medicine, Guangzhou, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,4,24]]},"reference":[{"key":"bibr1-03000605241244763","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0000000000003676"},{"key":"bibr2-03000605241244763","first-page":"126","volume":"54","author":"LiLiao SY","year":"2019","journal-title":"Chinese Journal of Obstetrics and Gynecology"},{"key":"bibr3-03000605241244763","first-page":"744","volume":"48","author":"Ma Y","year":"2019","journal-title":"Shaanxi Medical Journal"},{"key":"bibr4-03000605241244763","doi-asserted-by":"publisher","DOI":"10.1111\/head.12246"},{"key":"bibr5-03000605241244763","first-page":"86","volume":"9","author":"Li M","year":"2019","journal-title":"China Medicine and Pharmacy"},{"key":"bibr6-03000605241244763","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2018.07.044"},{"key":"bibr7-03000605241244763","first-page":"924","volume":"12","author":"Zhao X","year":"2010","journal-title":"Journal of Practical Obstetrics and Gynecology"},{"key":"bibr8-03000605241244763","doi-asserted-by":"publisher","DOI":"10.1007\/s100240010103"},{"key":"bibr9-03000605241244763","doi-asserted-by":"publisher","DOI":"10.1016\/j.placenta.2014.04.012"},{"key":"bibr10-03000605241244763","doi-asserted-by":"publisher","DOI":"10.1590\/1806-9282.62.07.687"},{"key":"bibr11-03000605241244763","first-page":"220","volume":"16","author":"Vuong ADB","year":"2022","journal-title":"J Family Reprod Health"}],"container-title":["Journal of International Medical Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/03000605241244763","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/03000605241244763","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/03000605241244763","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:49:48Z","timestamp":1777459788000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/03000605241244763"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,4]]},"references-count":11,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2024,4]]}},"alternative-id":["10.1177\/03000605241244763"],"URL":"https:\/\/doi.org\/10.1177\/03000605241244763","relation":{},"ISSN":["0300-0605","1473-2300"],"issn-type":[{"value":"0300-0605","type":"print"},{"value":"1473-2300","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,4]]},"article-number":"03000605241244763"}}
