We report the case of a 32-year-old woman with a history of migraine and oral contraceptive use who presented with sudden-onset headache on awakening, disorientation, and right hemiparesis, followed by focal seizures and National Institutes of Health Stroke Scale (NIHSS) progression from 3 to 7. Magnetic resonance venography confirmed extensive CVST involving the superior sagittal sinus and bilateral transverse and sigmoid sinuses. Mechanical thrombectomy was performed on hospital day 1 via a right jugular approach using a combined aspiration and NeVa stent retriever (5.5\u2009\u00d7\u200937\u2005mm) technique with a 6-second integration time; after six passes, near-complete recanalization of the superior sagittal sinus was achieved with restoration of antegrade venous drainage and no intraprocedural complications. The post-procedural course included neurological improvement (Medical Research Council grade 4\/5) and secondary intracranial hypertension (opening pressure 33 cmH\u2082O), which was managed conservatively. The patient was discharged after 12 days of hospitalization, with a modified Rankin Scale score of 0 at the 34-day follow-up visit. To our knowledge, this represents the first report of off-label NeVa stent retriever use for thrombectomy in the cerebral venous system; the device's higher mesh density may theoretically offer advantages for organized venous thrombi in large-caliber sinuses, expanding therapeutic options where consensus on optimal technique remains elusive.<\/jats:p>","DOI":"10.3389\/fradi.2026.1875234","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T05:40:58Z","timestamp":1784785258000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: Mechanical thrombectomy of cerebral venous sinuses using the NeVa stent retriever"],"prefix":"10.3389","volume":"6","author":[{"given":"Mar\u00eda Estefan\u00eda","family":"Pe\u00f1a Giraldo","sequence":"first","affiliation":[{"name":"School of Medicine, Fundaci\u00f3n Universitaria Juan N.
