While antegrade migration toward the heart or pulmonary arteries has been documented, the mechanism and management of retrograde migration toward the distal axillary vein remain unreported. We present a 61-year-old woman with stenosis at the left brachiocephalic vein\u2013superior vena cava junction and symptomatic retrograde migration of a bare-metal stent impacted in the axillary vein. After a systematic review excluded 10 conventional strategies, an innovative endovascular rescue was performed: intrastent fenestration with triangular-complex anchoring. Technical and clinical success was achieved with restored flow and complete symptom resolution. At the last follow-up (2\u2009years and 4\u2009months postoperatively), the patient had no recurrence of swelling, dialysis blood flow remained stable at 250\u2009mL\/min, and duplex ultrasound confirmed stable stent-complex position without restenosis. Beyond this singular case, our work provides a comprehensive review of management strategies, synthesizes them into a practical decision-making algorithm, and proposes an analysis of the factors driving retrograde migration. For highly selected cases of complex central venous stent migrations that are uncapturable and uncrossable, this technique represents a feasible and effective endovascular salvage option.<\/jats:p>","DOI":"10.1177\/11297298261490339","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T11:21:39Z","timestamp":1791458499000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Intravascular \u201cfenestration\u201d and \u201ctriangular anchoring\u201d techniques: A case of uncaptured central venous retrograde stent placement and a literature review"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-2213-2245","authenticated-orcid":false,"given":"Aiqiang","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, South China Hospital, Medical School, Shenzhen University, Shenzhen, Guangdong, P.
