Recanalization rates were as follows: PcoA preservation 40.5% (85\/210); incomplete PcoA occlusion 34.0% (18\/53); complete PcoA occlusion 14.3% (4\/28). Aneurysms &gt;7\u2009mm (HR 3.40; P&lt;0.01), retreatment for recanalization (HR 3.23; P&lt;0.01), and compromise of PcoA (P&lt;0.01) emerged from multivariate analysis as significant risk factors for recanalization. Compared with PcoA preservation, complete PcoA compromise conferred more favorable outcomes (HR 0.160), whereas incomplete compromise of PcoA fell short of statistical significance. Thromboembolic infarction related to PcoA compromise did not occur in any patient.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>PcoA compromise in conjunction with coil embolization of PcoA aneurysms appears safe in hypoplastic variants of PcoA, helping to prevent recanalization if complete occlusion is achieved.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/neurintsurg-2018-014233","type":"journal-article","created":{"date-parts":[[2018,10,8]],"date-time":"2018-10-08T09:57:58Z","timestamp":1538992678000},"page":"373-379","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Selective compromise of hypoplastic posterior communicating artery variants with aneurysms treatable by coil embolization: clinical and radiologic outcomes"],"prefix":"10.1136","volume":"11","author":[{"given":"Hyun Ho","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Chung-Ang University Hospital, Chung-Ang University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Dae","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong Hyun","family":"Yoo","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eung Koo","family":"Yeon","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeongjun","family":"Lee","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Dongguk University College of Medicine, Dongguk University Hospital, Ilsan, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Su Hwan","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun-Seung","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Won-Sang","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong Eun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0883-841X","authenticated-orcid":false,"given":"Moon Hee","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"},{"name":"Department of Neurosurgery, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,10,5]]},"reference":[{"key":"2025092912061615000_11.4.373.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2010.09.012"},{"key":"2025092912061615000_11.4.373.2","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A3541"},{"key":"2025092912061615000_11.4.373.3","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1007\/s00062-014-0308-4","article-title":"Posterior communicating artery compromise in coil embolization of posterior communicating artery aneurysms","volume":"25","author":"Cho","year":"2015","journal-title":"Clin Neuroradiol"},{"key":"2025092912061615000_11.4.373.4","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2828"},{"key":"2025092912061615000_11.4.373.5","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2051"},{"key":"2025092912061615000_11.4.373.6","doi-asserted-by":"crossref","unstructured":"Choi HH , Lee JJ , Cho YD , et al .
