Cavernous transformation of portal vein may be a sequel of portal vein thrombosis. Here the author reports a case of a 14-year-old boy presented with haemetemesis and melena, which was due to rupture of oesophageal varices as a result of portal hypertension. On further investigation, cavernous transformation of portal vein was identified on CT portovenogram and normal liver structure was evident on histology.<\/jats:p>","DOI":"10.1136\/bcr.12.2011.5331","type":"journal-article","created":{"date-parts":[[2012,2,28]],"date-time":"2012-02-28T09:19:33Z","timestamp":1330420773000},"page":"bcr1220115331","source":"Crossref","is-referenced-by-count":4,"title":["Cavernous transformation of portal vein a missed cause of extrahepatic portal hypertension"],"prefix":"10.1136","volume":"2012","author":[{"given":"Arvind Kumar","family":"Vaish","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nitin","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nirdesh","family":"Jain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhishek","family":"Agarwal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2012,2,28]]},"reference":[{"key":"2025042701341768000_2012.feb25_1.bcr1220115331.1","first-page":"47","article-title":"Functional protein C and anti-cardiolipin antibody in children with portal vein thrombosis.","volume":"20","author":"Yachha","year":"2001","journal-title":"Indian J Gastroenterol"},{"key":"2025042701341768000_2012.feb25_1.bcr1220115331.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(02)98915-4"},{"key":"2025042701341768000_2012.feb25_1.bcr1220115331.3","first-page":"1588","article-title":"Congenital hepatic fibrosis associated with cavernous transformation of the portal vein.","volume":"44","author":"Bayraktar","year":"1997","journal-title":"Hepatogastroenterology"},{"key":"2025042701341768000_2012.feb25_1.bcr1220115331.4","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(97)70216-3"},{"key":"2025042701341768000_2012.feb25_1.bcr1220115331.5","doi-asserted-by":"crossref","first-page":"109","DOI":"10.1148\/radiol.2311030108","article-title":"Congenital hepatic fibrosis: CT findings in 18 adults.","volume":"231","author":"Zeitoun","year":"2004","journal-title":"Radiology"},{"key":"2025042701341768000_2012.feb25_1.bcr1220115331.6","doi-asserted-by":"publisher","DOI":"10.1055\/s-0028-1085095"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.12.2011.5331","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T04:34:23Z","timestamp":1745728463000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.12.2011.5331"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,2,28]]},"references-count":6,"alternative-id":["10.1136\/bcr.12.2011.5331"],"URL":"https:\/\/doi.org\/10.1136\/bcr.12.2011.5331","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,2,28]]}}}
