We present a rare case of a Fontan patient with an enlarged azygous vein shunting into the pulmonary venous system, causing significant desaturation. As no standard access site provided a viable pathway for standard interventional occlusion, we opted for an ultrasound\u2010guided direct puncture at the level of the 12th thoracic vertebra with the patient in the prone position. The azygous vein was accessed via a dilated external vertebral venous plexus and successfully occluded using a vascular plug. This access technique expands the interventional options available for patients with complex anatomies or occluded conventional access site vessels.<\/jats:p>","DOI":"10.1002\/ccd.70436","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T05:26:31Z","timestamp":1766381191000},"page":"1039-1042","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Transparavertebral Occlusion of a Large Venovenous Collateral in a Fontan Patient"],"prefix":"10.1002","volume":"107","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3523-9535","authenticated-orcid":false,"given":"Michal","family":"Ji\u010d\u00ednsk\u00fd","sequence":"first","affiliation":[{"name":"Children's Heart Centre Second Faculty of Medicine, Charles University and Motol University Hospital Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0577-1440","authenticated-orcid":false,"given":"Theodor","family":"Adla","sequence":"additional","affiliation":[{"name":"Radiodiagnostic and Interventional Radiology Department Institute for Clinical and Experimental Medicine Prague Czech Republic"},{"name":"Department of Imaging Methods Second Faculty of Medicine, Charles University and Motol University Hospital Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3528-3202","authenticated-orcid":false,"given":"Ond\u0159ej","family":"Materna","sequence":"additional","affiliation":[{"name":"Children's Heart Centre Second Faculty of Medicine, Charles University and Motol University Hospital Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,21]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1055\/S\u20102001\u201014339"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.IJCARD.2015.04.065"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/CCD.21540"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.110.958264"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1522\u2010726X(199902)46:2"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/CCD.20080"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1148\/RADIOGRAPHICS.22.2.G02MR09337"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.70436","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ccd.70436","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.70436","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T16:53:43Z","timestamp":1791392023000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.70436"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,21]]},"references-count":7,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2026,3]]}},"alternative-id":["10.1002\/ccd.70436"],"URL":"https:\/\/doi.org\/10.1002\/ccd.70436","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,21]]},"assertion":[{"value":"2025-06-21","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-11","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-21","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
