The patient had 3\/5 quadriparesis and a Glasgow coma scale (GCS) score of 8, which merited neurocritical intensive care. Brain imaging suggested the presence of two lesions: (i) a fusiform aneurysm of 12\u2009\u00d7\u20097\u00a0mm in an accessory A2 artery of the anterior cerebral artery and (ii) an unruptured saccular aneurysm of 3.3\u2009\u00d7\u20092.8\u00a0mm in the distal segment of the basilar artery. He was deemed a candidate for microsurgical management. Postoperatively, he had 4\/5 quadriparesis, paresis of the right oculomotor nerve, and a GCS score of 13. A 3-month follow-up showed a significant improvement in neurological function with a score of 2 on the modified Rankin scale. The presented case illustrates the relevance of a nuanced acquaintance to operate in diseased anatomical variants and complex pathologies of narrow corridors.<\/jats:p>","DOI":"10.1093\/jscr\/rjad742","type":"journal-article","created":{"date-parts":[[2024,1,18]],"date-time":"2024-01-18T17:48:54Z","timestamp":1705600134000},"source":"Crossref","is-referenced-by-count":1,"title":["Microsurgery for brain aneurysms in an accessory A2 and basilar arteries: a rare case presentation and surgical video"],"prefix":"10.1093","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3661-7195","authenticated-orcid":false,"given":"Jhon E","family":"Bocanegra-Becerra","sequence":"first","affiliation":[{"name":"School of Medicine, Universidad Peruana Cayetano Heredia , Lima, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8427-2390","authenticated-orcid":false,"given":"Jos\u00e9 Luis","family":"Acha S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Vascular Neurosurgery and Skull Base Division , Department of Neurosurgery, , Lima, Peru"},{"name":"Hospital Nacional Dos de Mayo , Department of Neurosurgery, , Lima, Peru"},{"name":"School of Medicine, Universidad Nacional Mayor de San Marcos , Lima, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Contreras Montenegro","sequence":"additional","affiliation":[{"name":"Vascular Neurosurgery and Skull Base Division , Department of Neurosurgery, , Lima, Peru"},{"name":"Hospital Nacional Dos de Mayo , Department of Neurosurgery, , Lima, Peru"},{"name":"School of Medicine, Universidad Nacional Mayor de San Marcos , Lima, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,1,16]]},"reference":[{"key":"2024011817362801400_ref1","doi-asserted-by":"crossref","first-page":"825","DOI":"10.1212\/WNL.13.10.825","article-title":"Studies on the arteries of the brain: II.
