No vertical branches arose from the basilar bifurcation. The upper basilar artery gave rise to horizontal branches, which were studied with reference to their angle of origin. Perforating arteries arising from P<jats:sub>1<\/jats:sub> segments were found in all specimens. Rare branches were found to come from the inferior and anterior surfaces of P<jats:sub>1<\/jats:sub> segments. The anatomical patterns of these branches are discussed in the light of previous reports. Preoperative knowledge of some anatomical aspects (the position of the basilar apex, the angle between the right P<jats:sub>1<\/jats:sub> and left P<jats:sub>1<\/jats:sub> segments, and relationships to the dorsum sellae and the mammillary bodies) can help in the selection of a neurosurgical approach and may improve the operative results in the surgical treatment of basilar apex aneurysms.<\/jats:p>","DOI":"10.3171\/jns.1990.73.2.0259","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T18:18:52Z","timestamp":1242238732000},"page":"259-265","source":"Crossref","is-referenced-by-count":44,"title":["Perforating branches of the basilar bifurcation"],"prefix":"10.3171","volume":"73","author":[{"given":"Giuseppe","family":"Caruso","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Vincentelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00e9rard","family":"Giudicelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Grisoli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9","family":"Gouaze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"572","DOI":"10.3171\/jns.1984.60.3.0572","article-title":"Anomalies of the posterior communicating artery and their potential clinical significance.","volume":"60","author":"Bisaria","year":"1984"},{"key":"b2","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"671","DOI":"10.3171\/jns.1974.41.6.0671","article-title":"Surgical treatment of arterial aneurysms of the vertebrobasilar circulation.","volume":"41","author":"Chou","year":"1974"},{"key":"b3","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"230","DOI":"10.3171\/jns.1961.18.2.0230","article-title":"Bleeding aneurysms of the basilar artery.
