Embolization of the Arantius' duct is the first choice of treatment in infants and children. However, it carries the risk of coil migration into the systemic circulation in adult patients with larger Arantius ducts. Additionally, the primary closure of the Arantius' duct may result in acute portal hypertension. Herein, we present a two\u2010stage treatment for adult patent large ductus venosus (Arantius' duct). A 23\u2010year\u2010old female patient with hypoalbuminemia showed a patent large Arantius' duct (diameter\u2009=\u200945\u2009mm), intrahepatic portal venous hypoplasia, and multiple hepatic nodules with dynamic computed tomography (CT). Preoperative angiography showed the absence of the intrahepatic portal vein, and tentative occlusion of the Arantius' duct increased the portal pressure from 9 to 15\u2009mmHg with visualization of only a few portal branches. Therefore, we conducted a two\u2010stage treatment for the Arantius' duct. In the first stage, we used an open approach to perform angioplasty of the Arantius' duct to reduce the size from 45 to 8\u2009mm in diameter, which gradually increased the intrahepatic portal blood flow in the follow\u2010up CT scan. The second\u2010stage embolization of the Arantius' duct was performed using an interventional procedure via the internal jugular vein 4\u2009months after the first stage. The patient's recovery was uneventful, and post\u2010treatment CT showed increased intrahepatic portal flow. Serum albumin value increased from 2.7 to 3.7\u2009g\/dL 2\u2009weeks post\u2010treatment.<\/jats:p>","DOI":"10.1002\/ags3.70043","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T08:24:28Z","timestamp":1747729468000},"page":"1104-1108","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Two\u2010Stage Treatment for Adult Large Patent Ductus Venosus"],"prefix":"10.1002","volume":"9","author":[{"given":"Shohei","family":"Kudo","sequence":"first","affiliation":[{"name":"Department of Hepato\u2010Biliary\u2010Pancreatic Surgery Kyorin University Hospital  Mitaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiro","family":"Onozawa","sequence":"additional","affiliation":[{"name":"Department of Radiology Kyorin University Hospital  Mitaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryosuke","family":"Miyauchi","sequence":"additional","affiliation":[{"name":"Department of Radiology Kyorin University Hospital  Mitaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2438-7698","authenticated-orcid":false,"given":"Ryota","family":"Matsuki","sequence":"additional","affiliation":[{"name":"Department of Hepato\u2010Biliary\u2010Pancreatic Surgery Kyorin University Hospital  Mitaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7279-9702","authenticated-orcid":false,"given":"Yoshihiro","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Department of Hepato\u2010Biliary\u2010Pancreatic Surgery Kyorin University Hospital  Mitaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1998.tb01521.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-010-2662-x"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2015.01.009"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3468(94)90812-5"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0000000000000266"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.41.220.597"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800751028"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02010653"},{"issue":"2","key":"e_1_2_8_10_1","first-page":"179","article-title":"The Origin, Hormonal Nature, and Action of Hepatotrophic Substances in Portal Venous Blood","volume":"137","author":"Starzl T.
