We describe the case of a 20-year-old woman with IVC atresia who presented with a 3-month history of fatigue, oedema of the lower limbs and episodes of lipothymia. Transthoracic echocardiography and cardiac catheterization were performed, revealing interruption of the IVC with circulation through the azygos and hemiazygos system. An abdominal and pelvic computerized tomography (CT) scan confirmed the findings, demonstrating the absence of the IVC below the renal veins. Blood tests did not reveal any relevant results. These findings are consistent with the diagnosis of IVC atresia, a rare condition with no standard treatment. As a surgical approach was not possible, pharmacological measures were implemented for primary prevention of possible thrombotic events.<\/jats:p>","DOI":"10.12890\/2023_003744","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T03:24:33Z","timestamp":1674012273000},"source":"Crossref","is-referenced-by-count":0,"title":["Inferior Vena Cava Atresia: A Rare Vascular Malformation"],"prefix":"10.12890","volume":"10","author":[{"given":"Telma","family":"Alves","sequence":"first","affiliation":[{"name":"Medicina Interna, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]},{"given":"Diogo","family":"Leal","sequence":"first","affiliation":[{"name":"Medicina Interna, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]},{"given":"Ricardo","family":"Rodrigues","sequence":"first","affiliation":[{"name":"Medicina Interna, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]},{"given":"Carolina","family":"Terra","sequence":"first","affiliation":[{"name":"Radiologia, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]},{"given":"Sandra","family":"Santos","sequence":"first","affiliation":[{"name":"Medicina Interna, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]},{"given":"Joana","family":"Cascais Costa","sequence":"first","affiliation":[{"name":"Medicina Interna, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]},{"given":"F\u00e0tima","family":"Silva","sequence":"first","affiliation":[{"name":"Medicina Interna, Centro Hospitalar e Universit\u00e1rio de Coimbra, Portugal"}]}],"member":"10397","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"10.12890\/2023_003744_ref1","doi-asserted-by":"crossref","unstructured":"<li>Mabud TS, Sailer AM, Swee JKY, Tamboli M, Arendt VA, Jeon GS, et al.
