Radiological investigation, including abdominal ultrasound and magnetic resonance imaging revealed a focal irregular main portal vein wall and splenomegaly. Endoscopy showed major esophageal and gastric varices. Definitive diagnosis was made by direct, transhepatic portography revealing a focal stenosis associated with a dissection of the main portal vein. Percutaneous treatment including balloon angioplasty and stent placement resulted in complete re-expansion of the portal vein main branch. Clinical and radiological follow-up over 5 years showed complete disappearance of all clinical signs and normalization of laboratory data and splenic volume.<\/jats:p>","DOI":"10.1177\/2047981613492723","type":"journal-article","created":{"date-parts":[[2013,7,8]],"date-time":"2013-07-08T20:36:23Z","timestamp":1373315783000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Focal portal vein stenosis in an adolescent potentially related to complicated umbilical catheter insertion in the neonatal period"],"prefix":"10.1177","volume":"2","author":[{"given":"Geert","family":"Maleux","sequence":"first","affiliation":[{"name":"Department of Radiology, UZ Leuven\/Department of Imaging & Pathology, KU Leuven"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilse","family":"Hoffman","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Hospitals Leuven"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sam","family":"Heye","sequence":"additional","affiliation":[{"name":"Department of Radiology, UZ Leuven\/Department of Imaging & Pathology, KU Leuven"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Cassiman","sequence":"additional","affiliation":[{"name":"Department of Hepatology, University Hospitals Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,7,8]]},"reference":[{"key":"ARR492723C1","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-003-0026-9"},{"key":"ARR492723C2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2009.09.001"},{"key":"ARR492723C3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2009.02.010"},{"key":"ARR492723C4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2007.06.029"},{"key":"ARR492723C5","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.180.4.1801147"},{"key":"ARR492723C6","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-008-9455-9"}],"container-title":["Acta Radiologica Short Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2047981613492723","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2047981613492723","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2047981613492723","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T11:55:19Z","timestamp":1777377319000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2047981613492723"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,5]]},"references-count":6,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2013,5]]}},"alternative-id":["10.1177\/2047981613492723"],"URL":"https:\/\/doi.org\/10.1177\/2047981613492723","relation":{},"ISSN":["2047-9816"],"issn-type":[{"value":"2047-9816","type":"print"}],"subject":[],"published":{"date-parts":[[2013,5]]},"article-number":"2047981613492723"}}
