In an autopsy series of 110 patients with subarachnoid hemorrhage (SAH), the incidence of this entity was 4.5%, with all five cases progressing rapidly to death from massive SAH. Cases of intracranial vertebral dissection can be divided clearly into two groups based on the clinical and pathological features. In the first group, the dissection is confined to the vertebral artery and a massive SAH develops caused by the rupture of the arterial wall. The plane of dissection is mainly subadventitial. In the second group, brain-stem infarction develops resulting from luminal occlusion by intramural hematoma. The plane of dissection is mainly subintimal, with the dissection extending to the basilar artery. The condition in the second group affects patients at a younger age. If the lesion is localized within the vertebral artery and does not extend to the basilar artery, the disease seems not to be fatal. The clinical features of the vertebral dissection are largely determined by the plane and extension of dissection. Vertebral artery dissection is due to many causative factors including hypertension, congenital or degenerative changes in the arterial wall, and anatomical and pathological characteristics of the vertebral artery.<\/jats:p>","DOI":"10.3171\/jns.1991.75.6.0874","type":"journal-article","created":{"date-parts":[[2009,5,19]],"date-time":"2009-05-19T16:25:34Z","timestamp":1242750334000},"page":"874-882","source":"Crossref","is-referenced-by-count":220,"title":["A clinicopathological study of dissecting aneurysms of the intracranial vertebral artery"],"prefix":"10.3171","volume":"75","author":[{"given":"Osamu","family":"Sasaki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Ogawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuo","family":"Koike","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayuki","family":"Koizumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuichi","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Arch Neurol","first-page":"773","article-title":"Intracranial hemorrhage produced by spontaneous dissecting intracranial aneurysm.","volume":"39","author":"Adams","year":"1982"},{"key":"b2","series-title":"J Neurosurg","first-page":"882","article-title":"Intracranial dissecting aneurysms of the posterior circulation, Report of six cases and review of the literature.","volume":"61","author":"Berger","year":"1984"},{"key":"b3","series-title":"Br Med J","first-page":"790","article-title":"Spontaneous dissecting aneurysms of the cervical internal carotid artery.","volume":"2","author":"Brice","year":"1981"},{"key":"b4","series-title":"Brain","first-page":"797","article-title":"The pathogenesis of cerebral aneurysms.","volume":"89","author":"Crompton","year":"1966"},{"key":"b5","series-title":"Rev Neurol","first-page":"95","article-title":"An\u00e9vrysme diss\u00e9quant vert\u00e9bro-basilaire.","volume":"128","author":"Escourolle","year":"1973"},{"key":"b6","series-title":"Zentralbl Allg Pathol","first-page":"243","article-title":"\u00dcber den Ursprung gewisser Aneurysmen der basalen Hirnarterien.","volume":"44","author":"Forbus","year":"1929"},{"key":"b7","series-title":"J Neurosurg","first-page":"325","article-title":"Subarachnoid hemorrhage from intracranial dissecting aneurysm.","volume":"60","author":"Friedman","year":"1984"},{"key":"b8","series-title":"J Pathol Baeteriol","first-page":"213","article-title":"Medial defects in the circle of Willis and their relation to aneurysm formation.","volume":"51","author":"Glynn","year":"1940"},{"key":"b9","series-title":"Arch Pathol","first-page":"142","article-title":"Pathogenesis of dissecting aneurysm of the aorta.","volume":"53","author":"Gore","year":"1952"},{"key":"b10","series-title":"J Neurosurg","first-page":"693","article-title":"Dissecting aneurysm of the cerebral arteries.
