We describe the first reported case of a subclavian vein pseudoaneurysm following percutaneous axillary lymph node biopsy. A 42-year-old woman presented with a progressively enlarging, painless right neck mass 18\u2009months after treatment for node-positive breast cancer. Imaging with duplex ultrasound and contrast-enhanced computed tomography demonstrated a large saccular pseudoaneurysm arising from the right subclavian vein without arterial communication. Following initial observation, open surgical repair was performed via a supraclavicular approach, with excision of the pseudoaneurysm and primary repair of the vein. The patient recovered without complications and remained asymptomatic at follow-up. This case adds to the limited literature on venous pseudoaneurysms, highlights a novel iatrogenic mechanism, and supports open aneurysmorrhaphy as a safe and effective treatment option in appropriately selected patients.<\/jats:p>","DOI":"10.1177\/23247096251385362","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T10:26:41Z","timestamp":1761733601000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Right Subclavian Vein Pseudoaneurysm Following Percutaneous Axillary Lymph Node Biopsy: A Case Report"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2209-1161","authenticated-orcid":false,"given":"Harsh","family":"Patel","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Royal Melbourne Hospital, Parkville, VIC, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,10,29]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2006.25.6.771"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/87564793231221742"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1984.01390210087019"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-196406000-00004"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/11297298211018062"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsc.2015.07.001"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2007.01.017"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1080\/02841850510021175"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10016-004-0151-1"},{"key":"e_1_3_2_11_2","first-page":"527","article-title":"Thoracic venous aneurysms.
