Although the treatment went very well and the patient recovered very well, angiography 6 months after the operation showed that left PCoA had occluded and the aneurysm disappeared. The temporary recanalization of occluded ophthalmic segment of ICA can be a pathway for interventional therapy. Mechanism and preventive measures for spontaneous occlusion of the PCoA harboring an aneurysm still needs further study.<\/jats:p>","DOI":"10.4103\/0028-3886.391389","type":"journal-article","created":{"date-parts":[[2024,1,3]],"date-time":"2024-01-03T11:03:32Z","timestamp":1704279812000},"page":"1241-1243","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Parent Artery Chronical Occlusion after Endovascular Treatment of a Unruptured \u201cTrue\u201d Posterior Communicating Artery Aneurysm"],"prefix":"10.4103","volume":"71","author":[{"given":"Baoyuan","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Neurosurgery and Laboratory of Neurosurgery, Lanzhou University Second Hospital, Institute of Neurology, Lanzhou University, Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linjuan","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Lanzhou University Second Hospital, Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shouyuan","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Laboratory of Neurosurgery, Lanzhou University Second Hospital, Institute of Neurology, Lanzhou University, Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hailin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Laboratory of Neurosurgery, Lanzhou University Second Hospital, Institute of Neurology, Lanzhou University, Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2023,12,20]]},"reference":[{"key":"R1-20260511","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1177\/1591019919874603","article-title":"Treatment of true posterior communicating artery aneurysms: Endovascular experience in a single center","volume":"26","author":"Liu","year":"2020","journal-title":"Interv Neuroradiol"},{"key":"R2-20260511","doi-asserted-by":"crossref","first-page":"1191","DOI":"10.1007\/s00234-019-02277-y","article-title":"Feasibility and midterm outcomes of endovascular embolization for true posterior communicating artery aneurysms","volume":"61","author":"Wang","year":"2019","journal-title":"Neuroradiology"},{"key":"R3-20260511","doi-asserted-by":"crossref","first-page":"1340","DOI":"10.4103\/0028-3886.304098","article-title":"True posterior communicating artery aneurysms: Report of 17 surgically treated patients and review of the literature","volume":"68","author":"Guo","year":"2020","journal-title":"Neurol India"},{"key":"R4-20260511","doi-asserted-by":"crossref","first-page":"299","DOI":"10.3174\/ajnr.A6928","article-title":"Endovascular recanalization of symptomatic nonacute intracranial internal carotid artery occlusion: Proposal of a new angiographic classification","volume":"42","author":"Gao","year":"2021","journal-title":"AJNR Am J Neuroradiol"},{"key":"R5-20260511","doi-asserted-by":"crossref","first-page":"15","DOI":"10.4103\/2152-7806.175898","article-title":"Spontaneous thrombosis of giant intracranial aneurysm and posterior cerebral artery followed by also spontaneous recanalization","volume":"7","author":"de Aguiar","year":"2016","journal-title":"Surg Neurol Int"},{"key":"R6-20260511","doi-asserted-by":"crossref","first-page":"856","DOI":"10.1017\/cjn.2016.282","article-title":"Spontaneous thrombosis of an unruptured saccular aneurysm causing MCA infarction","volume":"43","author":"Fomenko","year":"2016","journal-title":"Can J Neurol Sci"}],"container-title":["Neurology India"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/0028-3886.391389","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T16:25:19Z","timestamp":1786724719000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/0028-3886.391389"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,11]]},"references-count":6,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2023]]}},"URL":"https:\/\/doi.org\/10.4103\/0028-3886.391389","relation":{},"ISSN":["0028-3886","1998-4022"],"issn-type":[{"value":"0028-3886","type":"print"},{"value":"1998-4022","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,11]]},"assertion":[{"value":"2021-02-14","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-07-06","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
