Clinically, two patients presented with subarachnoid hemorrhage and two with brain-stem ischemia. In two cases of ruptured arterial dissection of the posterior cerebral artery, angiography demonstrated fusiform and \u201csausage-like\u201d dilatation of the involved vessel. In two cases of occlusive dissection of the basilar artery, angiography revealed the typical \u201cstring sign.\u201d All four patients were treated conservatively: three survive in good clinical condition and one remains disabled. Follow-up angiograms showed spontaneous healing of the lesion with return to an almost normal arterial configuration in two cases; residual narrowing corresponding to the dissection was the most notable finding in the other two. It is recommended that, in a subset of neurologically stable patients, angiographic monitoring is undertaken to assess the tendency for spontaneous repair before surgical intervention is planned.<\/jats:p>","DOI":"10.3171\/jns.1991.75.1.0069","type":"journal-article","created":{"date-parts":[[2009,5,19]],"date-time":"2009-05-19T16:22:46Z","timestamp":1242750166000},"page":"69-72","source":"Crossref","is-referenced-by-count":87,"title":["Benign arterial dissections of the posterior circulation"],"prefix":"10.3171","volume":"75","author":[{"given":"Eugenio","family":"Pozzati","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Padovani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Fabrizi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luciano","family":"Sabattini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giulio","family":"Gaist","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":"Stroke","first-page":"294","article-title":"Dissecting aneurysms of the basilar artery in two patients.","volume":"10","author":"Alexander","year":"1979"},{"key":"b3","series-title":"J Neurosurg","first-page":"882","article-title":"Intracranial dissecting aneurysms of the posterior circulation.
