Ultrasound imaging wasused for the identification and follow-up of anatomical variants. Follow-up was conducted once every four weeks prenatally\u00a0and every two months postnatally, mainly concerned on the adverse events that may appear.Results: There were 20848 cases\u00a0with anatomical variants of fetal HVS identified from 46179 candidates during the study period. Following the anatomical\u00a0position of variants occurring, four main divisions were present: main portal vein variants (17.9%), intrahepatic portal vein\u00a0variants (21.30%), intrahepatic persistent right umbilical vein (0.27%) and hepatic vein variants (5.67%). In the fetal period,\u00a0the pregnancy of all cases was normally continued, except that the pregnancy of two cases, which were associated with multiple\u00a0anomalies and were terminated by their parents. After birth, approximately 99.47% of the cases with isolated variants orbeing associated no clinic significant anomalies were normally alive. Approximately 0.50% cases were associated with simple\u00a0ventricular septum defect or tetralogy of Fallot and further treatment was needed.Conclusion: The anatomical variants of fetal\u00a0HVS may appear as numerical, morphological or positional variants of MPV, intrahepatic PV branches, intrahepatic PRUV\u00a0and HVs. The majority of cases are isolated or their associated anomalies are not clinically significant and have normal lifeafter birth.<\/jats:p>","DOI":"10.11152\/mu-3203","type":"journal-article","created":{"date-parts":[[2021,11,10]],"date-time":"2021-11-10T16:47:09Z","timestamp":1636562829000},"page":"160","source":"Crossref","is-referenced-by-count":0,"title":["A large-scale investigation by ultrasound of fetal hepatic venous system variants in China"],"prefix":"10.11152","volume":"24","author":[{"given":"Zhongshan","family":"Gou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinxin","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baojuan","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongmei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caifang","family":"Ni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2022,5,25]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3203\/1969","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3203\/1969","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,3]],"date-time":"2022-06-03T18:44:48Z","timestamp":1654281888000},"score":1,"resource":{"primary":{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/3203"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,25]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2022,5,25]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-3203","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2022,5,25]]}}}
