Two days prior to the swelling he had developed significant abdominal pain following a treadmill exercise session. Ultrasound imaging revealed extensive deep vein thrombosis involving bilateral ileo-femoral venous systems, extending up the inferior vena cava (IVC). Further investigation using a CT venogram revealed the rare congenital anomaly of hypoplasia of the renal IVC. Successful treatment involved 48 hours of an intravenous unfractionated heparin infusion, followed by lifelong anticoagulation.<\/jats:p>","DOI":"10.1136\/bcr-2021-246555","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T10:51:05Z","timestamp":1646045465000},"page":"e246555","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Rare congenital abnormality resulting in spontaneous bilateral deep venous thrombosis and pulmonary emboli in a young healthy man"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2660-617X","authenticated-orcid":false,"given":"Celina","family":"Ledgard","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Mercy University Hospital, Cork, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Clarke","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Mercy University Hospital, Cork, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerald Thomas","family":"McGreal","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Mercy University Hospital, Cork, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,2,28]]},"reference":[{"key":"2025082708355450000_15.2.e246555.1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000078468.11849.66"},{"key":"2025082708355450000_15.2.e246555.2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2016\/4965458","article-title":"The typical presentation spectrum of deep vein thrombosis associated with inferior vena cava malformations","volume":"2016","author":"Pozzi","year":"2016","journal-title":"Thrombosis"},{"key":"2025082708355450000_15.2.e246555.3","doi-asserted-by":"publisher","DOI":"10.1148\/rg.283075101"},{"key":"2025082708355450000_15.2.e246555.4","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.180.3.1800729"},{"key":"2025082708355450000_15.2.e246555.5","doi-asserted-by":"publisher","DOI":"10.1177\/1358863X10391355"},{"key":"2025082708355450000_15.2.e246555.6","doi-asserted-by":"crossref","DOI":"10.1186\/s12887-019-1567-7","article-title":"Thrombophlebitis hiding under a KILT - case report on 40 years long-term follow-up of neonatal renal vein thrombosis","volume":"19","author":"Lauener","year":"2019","journal-title":"BMC Pediatr"},{"key":"2025082708355450000_15.2.e246555.7","doi-asserted-by":"crossref","first-page":"4","DOI":"10.5173\/ceju.2011.01.art1","article-title":"Anomalies of the inferior vena cava and renal veins and implications for renal surgery","volume":"64","author":"Eldefrawy","year":"2011","journal-title":"Cent European J Urol"},{"key":"2025082708355450000_15.2.e246555.8","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2015\/864047","article-title":"Deep venous thrombosis of the leg, associated with agenesis of the infrarenal inferior vena cava and hypoplastic left kidney (KILT syndrome) in a 14-year-old child","volume":"2015","author":"Bami","year":"2015","journal-title":"Case Rep Pediatr"},{"key":"2025082708355450000_15.2.e246555.9","doi-asserted-by":"crossref","first-page":"38","DOI":"10.3941\/jrcr.v8i4.1572","article-title":"The curious case of the disappearing IVC: a case report and review of the aetiology of inferior vena cava agenesis","volume":"8","author":"Paddock","year":"2014","journal-title":"J Radiol Case Rep"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-246555","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T15:36:02Z","timestamp":1756308962000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-246555"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,2]]},"references-count":9,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2022,2,28]]},"published-print":{"date-parts":[[2022,2]]}},"alternative-id":["10.1136\/bcr-2021-246555"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-246555","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2022,2]]}}}
