Clinical workup demonstrated advanced papilledema, tortuous optic nerves, flattened globes and intracranial pressure of &gt;55\u2009cm H<jats:sub>2<\/jats:sub>O. Diagnostic cerebral angiogram demonstrated a Cognard IIA tentorial dural arteriovenous fistula (dAVF) associated with transverse sinus stenosis. Venous manometry demonstrated a pressure gradient of 28\u2009mm Hg across the stenosis. Given acute symptoms of elevated intracranial pressure and significant functional gradient, venous sinus balloon angioplasty and stenting were performed, which resulted in near resolution of functional gradient, immediate improvement of symptoms and resolution of retrograde venous flow, thus downgrading his dAVF to Cognard I. At 3-month follow-up, angiographic improvement in dAVF grade was maintained, with durable improvement in papilledema and headaches.<\/jats:p>","DOI":"10.1136\/bcr-2025-266426","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T04:05:21Z","timestamp":1753243521000},"page":"e266426","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Demonstration of physiologic, clinical and angiographic improvement of dural arteriovenous fistula via primary transverse sinus stenting"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8819-2198","authenticated-orcid":false,"given":"Christina P","family":"Rossitto","sequence":"first","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nanthiya","family":"Sujijantarat","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edwin","family":"Owolo","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9538-7708","authenticated-orcid":false,"given":"Varun","family":"Padmanaban","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James D","family":"Rabinov","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neuroradiology and Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher J","family":"Stapleton","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2958-3484","authenticated-orcid":false,"given":"Robert W","family":"Regenhardt","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aman B","family":"Patel","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital, Department of Neurosurgery, Harvard University, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,7,22]]},"reference":[{"key":"2025082709493530000_18.7.e266426.1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1995.82.2.0166"},{"key":"2025082709493530000_18.7.e266426.2","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.116.012784"},{"key":"2025082709493530000_18.7.e266426.3","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1994.80.5.0884"},{"key":"2025082709493530000_18.7.e266426.4","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2006.104.2.254"},{"key":"2025082709493530000_18.7.e266426.5","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000040097","article-title":"Dural arteriovenous fistula may be occluded through recanalization of impaired venous sinuses","volume":"103","author":"Zhao","year":"2024","journal-title":"Medicine (Baltimore)"},{"key":"2025082709493530000_18.7.e266426.6","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1177\/159101990300900111","article-title":"Endovascular Treatment of a Dural Arteriovenous Fistula of the Transverse Sinus by Recanalisation, Angioplasty and Stent Deployment.
