Typically, these malformations present with a wide range of nonspecific symptoms indicative of thoracolumbar myelopathy. However, patients with spinal dural arteriovenous fistulas may rarely present with subarachnoid hemorrhage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic review of MEDLINE and Embase databases was performed querying for cases of spinal dural arteriovenous fistulas with subarachnoid hemorrhage. Patient characteristics and outcomes investigated included spinal level of the fistula, delay of diagnosis, Hunt and Hess grade, interventions, recurrence of the fistula, and postoperative disability. Additionally, we present a unique case in which subarachnoid hemorrhage resulted from a spinal dural arteriovenous fistula that was refractory to multiple endovascular and open surgical interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 116 records identified, 45 studies were included comprising 80 patients with spinal dural arteriovenous fistula and subarachnoid hemorrhage. The most common locations of the spinal dural arteriovenous fistula were in the cervical spine (57.5%) and at the craniocervical junction (35%). Patients were treated with open surgical ligation (60.0%), endovascular embolization (22.5%), or an open surgical procedure following persistent symptoms after endovascular treatment (10.0%). Overall, the prognoses among the treated patients were favorable with only two reported (2.5%) mortalities. Rates of neurologic recovery were similar when comparing endovascular and open surgical treatment. Endovascular treatment with coil embolization of a C1\u2013C2 spinal dural arteriovenous fistula presenting as subarachnoid hemorrhage is also described.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Spinal dural arteriovenous fistulas, particularly in the cervical spine, could be considered as a potential etiology for subarachnoid hemorrhage patients with no obvious intracranial cause. Treatment with either open surgery or embolization appears to offer a positive prognosis for both functional and angiographic outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15910199251328721","type":"journal-article","created":{"date-parts":[[2025,7,15]],"date-time":"2025-07-15T07:57:31Z","timestamp":1752566251000},"page":"2698-2708","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Spinal dural arteriovenous fistulas presenting as intracranial subarachnoid hemorrhage: A systematic review"],"prefix":"10.1177","volume":"32","author":[{"given":"Bridget","family":"Nolan","sequence":"first","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3559-2766","authenticated-orcid":false,"given":"Christian","family":"Rajkovic","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Galadu","family":"Subah","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alis J","family":"Dicpinigaitis","sequence":"additional","affiliation":[{"name":"New York Presbyterian\u2014Weill Cornell Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Feldstein","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4761-7828","authenticated-orcid":false,"given":"Ankita","family":"Jain","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eris","family":"Spirollari","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6236-1190","authenticated-orcid":false,"given":"Ariel","family":"Sacknovitz","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilya","family":"Frid","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merritt","family":"Kinon","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Wainwright","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chirag D","family":"Gandhi","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gurmeen","family":"Kaur","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4461-7005","authenticated-orcid":false,"given":"Fawaz","family":"Al-Mufti","sequence":"additional","affiliation":[{"name":"School of Medicine"},{"name":"New York Medical College"},{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,7,15]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3171\/FOC.2009.26.1.E4"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1485"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11883-013-0335-7"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clineuro.2019.105371"},{"key":"e_1_3_2_6_2","first-page":"854","article-title":"Cervical dural arteriovenous fistulae manifesting as subarachnoid hemorrhage: report of two cases and literature review","volume":"25","author":"Aviv RI","year":"2004","unstructured":"Aviv RI, Shad A, Tomlinson G, et al.
