The patient was treated repeatedly, because of restenosis. Due to complete occlusion of the graft and subclavian vein as well as a liquid tumor located around the stenotic segment of the vein, we resected the left subclavian vein via a trap-door thoracotomy and inserted a PTFE-graft. Histological examination of the resected tissue identified metastasis from the urothelial carcinoma as the underlying cause of the stenosis. Malignant tumors are an infrequent etiology of AV-access dysfunction, and there are hardly any data on transgender patients. This case report provides an overview of the current data concerning these unique circumstances.<\/jats:p>","DOI":"10.1177\/11297298251313620","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T00:17:36Z","timestamp":1738282656000},"page":"326-331","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Metastasis of an urothelial carcinoma as rare cause of an AV-graft dysfunction in a transgender patient"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-3237-5712","authenticated-orcid":false,"given":"Abdalla","family":"Marei","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Helios Klinikum Krefeld, Krefeld, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Hohls","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Helios Klinikum Krefeld, Krefeld, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aristotelis","family":"Touloumtzidis","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Helios Klinikum Krefeld, Krefeld, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcus","family":"Katoh","sequence":"additional","affiliation":[{"name":"Department of Radiology, Helios Klinikum Krefeld, Krefeld, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabor","family":"G\u00e4bel","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Helios Klinikum Krefeld, Krefeld, Germany"},{"name":"Institute of Laboratory Medicine, University Hospital, LMU Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,1,30]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3389\/fneph.2023.1280666"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-023-03461-7"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsv.2019.03.016"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1067\/mva.2000.107988"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2015.08.016"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.5301\/jva.5000648"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.5301\/JVA.2011.8419"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-021-03030-w"},{"key":"e_1_3_2_10_2","first-page":"1420136","article-title":"A review of percutaneous transluminal angioplasty in hemodialysis fistula","volume":"2018","author":"Bountouris I","year":"2018","unstructured":"Bountouris I, Kritikou G, Degermetzoglou N, et al.
