In young adults who lack predisposing risk factors but nonetheless develop extensive or bilateral DVTs, AIVC should be considered. We describe a case of a previously healthy 17-year-old male patient who developed an extensive renal vein thrombus due to the absence of the superior portion of his IVC compounded with previously undiagnosed antithrombin III deficiency. We discuss the diagnosis and management of this complicated condition.<\/jats:p>","DOI":"10.1136\/bcr-2014-205729","type":"journal-article","created":{"date-parts":[[2015,1,27]],"date-time":"2015-01-27T07:37:45Z","timestamp":1422344265000},"page":"bcr2014205729","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Congenital atresia of the inferior vena cava and antithrombin III deficiency in a young adult: compounding risk factors for deep vein thrombosis"],"prefix":"10.1136","volume":"2015","author":[{"given":"Laura","family":"Muscianese","sequence":"first","affiliation":[{"name":"University of California, Irvine, Orange, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald R","family":"Seese","sequence":"additional","affiliation":[{"name":"University of California, Irvine, Orange, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Graham","sequence":"additional","affiliation":[{"name":"University of California, Irvine, Orange, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James H","family":"Williams","sequence":"additional","affiliation":[{"name":"University of California, Irvine, Orange, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,1,27]]},"reference":[{"key":"2025082802422934000_2015.jan27_2.bcr2014205729.1","doi-asserted-by":"publisher","DOI":"10.2459\/JCM.0b013e328014a8a4"},{"key":"2025082802422934000_2015.jan27_2.bcr2014205729.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.05.054"},{"key":"2025082802422934000_2015.jan27_2.bcr2014205729.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2011.01.449"},{"key":"2025082802422934000_2015.jan27_2.bcr2014205729.4","doi-asserted-by":"crossref","first-page":"697.e1","DOI":"10.1016\/j.avsg.2011.02.027","article-title":"Superficial and deep vein thrombosis associated with congenital absence of the infrahepatic inferior vena cava in a young male patient","volume":"25","author":"O'Connor","year":"2011","journal-title":"Ann Vasc Surg"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-205729","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:42:38Z","timestamp":1756374158000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-205729"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,1,27]]},"references-count":4,"alternative-id":["10.1136\/bcr-2014-205729"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-205729","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2015,1,27]]}}}
