The usual pathogenesis of aneurysms in this location is either penetrating or blunt trauma with resultant pseudoaneurysm formation. We report a postpartum patient with a presumed traumatic pseudoaneurysm of the extracranial vertebral artery presenting with subarachnoid hemorrhage.<\/jats:p>\n          <jats:p>A 41-year-old woman had three episodes of neck stiffness 1 month after an uncomplicated vaginal delivery. The last episode, 3 days before admission, was accompanied by intense neck and head pain and paresthesias that extended into the left arm, thumb, and forefinger.<\/jats:p>\n          <jats:p>Lumbar puncture showed subarachnoid hemorrhage. Angiography revealed a left vertebral artery dissection from C6-7 to C3 with pseudoaneurysm at C5-6. Computed tomography demonstrated impingement of the C6 root at the foramen by this lesion. The lesion was successfully treated by balloon occlusion of the vertebral artery.<\/jats:p>\n          <jats:p>We present a patient with an extracranial vertebral pseudoaneurysm with subarachnoid hemorrhage and cervical root impingement. To our knowledge, this is the first case of such a lesion presenting as subarachnoid hemorrhage. The lesion was successfully treated using endovascular techniques.<\/jats:p>","DOI":"10.1161\/01.str.24.9.1397","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:08:03Z","timestamp":1308341283000},"page":"1397-1399","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":14,"title":["Extracranial vertebral artery pseudoaneurysm presenting as subarachnoid hemorrhage."],"prefix":"10.1161","volume":"24","author":[{"given":"S S","family":"Kaplan","sequence":"first","affiliation":[{"name":"Neurosurgical Service, Massachusetts General Hospital, Boston 02114."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C S","family":"Ogilvy","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Massachusetts General Hospital, Boston 02114."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Massachusetts General Hospital, Boston 02114."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Gress","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Massachusetts General Hospital, Boston 02114."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Pile-Spellman","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Massachusetts General Hospital, Boston 02114."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","container-title":["Stroke"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.STR.24.9.1397","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T22:27:22Z","timestamp":1715552842000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.STR.24.9.1397"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,9]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[1993,9]]}},"alternative-id":["10.1161\/01.STR.24.9.1397"],"URL":"https:\/\/doi.org\/10.1161\/01.str.24.9.1397","relation":{},"ISSN":["0039-2499","1524-4628"],"issn-type":[{"value":"0039-2499","type":"print"},{"value":"1524-4628","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,9]]},"assertion":[{"value":"1993-09-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
