Interestingly, the PPOA was originating from the A\n                    <jats:sub>1<\/jats:sub>\n                    segment of the anterior cerebral artery and coursed anteromedially along the olfactory tract. Moreover, the PPOA in this case had 2 branches: the branch making a hairpin turn and supplying the distal part of the anterior cerebral artery territory (Type 1), and the branch extending to the cribriform plate to supply the nasal cavity (Type 2). To the best of the authors' knowledge, this is a new variant (Type 3) of PPOA associated with a ruptured aneurysm. The clinical implications of this case are discussed in terms of the embryological aspects.\n                  <\/jats:p>","DOI":"10.3171\/2012.3.jns111932","type":"journal-article","created":{"date-parts":[[2012,4,27]],"date-time":"2012-04-27T11:07:28Z","timestamp":1335524848000},"page":"26-28","source":"Crossref","is-referenced-by-count":23,"title":["New variant of persistent primitive olfactory artery associated with a ruptured aneurysm"],"prefix":"10.3171","volume":"117","author":[{"given":"Nobutaka","family":"Horie","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minoru","family":"Morikawa","sequence":"additional","affiliation":[{"name":"Radiology, Nagasaki University School of Medicine, Nagasaki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuji","family":"Fukuda","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiko","family":"Suyama","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Izumi","family":"Nagata","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns111932","series-title":"No Shinkei Geka","first-page":"203","article-title":"[A ruptured cerebral aneurysm of the fronto-orbital artery and a coexisting anastomosis with the anterior ethmoidal artery\u2014a case report.]","volume":"14","author":"Enomoto","year":"1986"},{"key":"b2-jns111932","series-title":"No Shinkei Geka","first-page":"781","article-title":"[An aneurysm of the distal anterior cerebral artery with a remarkably anomalous configuration.]","volume":"16","author":"Hanakita","year":"1988"},{"key":"b3-jns111932","series-title":"No Shinkei Geka","first-page":"933","article-title":"[Persistent primitive olfactory artery: report of 5 cases.]","volume":"27","author":"Kaneko","year":"1999"},{"key":"b4-jns111932","series-title":"J Korean Neurosurg Soc","first-page":"290","article-title":"Diagnosis of persistent primitive olfactory artery using computed tomography angiography","volume":"49","author":"Kim","year":"2011"},{"key":"b5-jns111932","series-title":"AJNR Am J Neuroradiol","first-page":"2075","article-title":"Anomalous origin of the callosomarginal artery from the A1 segment with an associated saccular aneurysm","volume":"27","author":"Krishnamoorthy","year":"2006"},{"key":"b6-jns111932","series-title":"Brain Dev","first-page":"318","article-title":"Combination of olfactory course anterior cerebral artery and accessory middle cerebral artery (MCA) with occluded in situ MCA and related moyamoya phenomenon","volume":"31","author":"Lin","year":"2009"},{"key":"b7-jns111932","series-title":"Anat Anz","first-page":"477","article-title":"A case of peristence of the primitive olfactory artery","volume":"121","author":"Moffat","year":"1967"},{"key":"b8-jns111932","series-title":"Acta Neurochir (Wien)","first-page":"397","article-title":"Cerebral aneurysm associated with persistent primitive olfactory artery aneurysm","volume":"140","author":"Nozaki","year":"1998"},{"key":"b9-jns111932","series-title":"Contrib Embryol","first-page":"205","article-title":"Development of cranial arteries in human embryo","volume":"32","author":"Padget","year":"1948"},{"key":"b10-jns111932","series-title":"J Neurosurg","first-page":"138","article-title":"Aneurysm of a persistent primitive olfactory artery.
