Patients with UIA are treated with close observation, endovascular coiling or surgical clipping. The proportion of endovascular coiling has been rising. However, complications such as cerebral infarction (CI), intracranial hemorrhage (ICRH), and death remain crucial issues after coil treatment. (2) Methods: We analyzed the incidence and risk factors of complications after the use of coil in patients with UIA based on the patients\u2019 characteristics. We utilized the Health Insurance Review and Assessment (HIRA) database. Patients treated with coils for UIA between 1 January 2015 and 1 December 2021 were retrospectively analyzed. (3) Results: Of the total 35,140 patients, 1062 developed ICRH, of whom 87 died, with a mortality rate of 8.2%. Meanwhile, 749 patients developed CI, of whom 29 died, with a mortality rate of 3.9%. The overall mortality rate was 1.8%. In a univariate analysis of the risk factors, older age, males, a higher Charlson Comorbidity Index (CCI) score, and diabetes increase the risk of CI. Meanwhile, males with higher CCI scores and hemiplegia or paraplegia show increased ICRH risk. Older age, males and metastatic solid tumors relate to increased mortality risk. (4) Conclusions: This study is significant in that the complications based on the patient\u2019s underlying medical condition were analyzed.<\/jats:p>","DOI":"10.3390\/jcm13041094","type":"journal-article","created":{"date-parts":[[2024,2,15]],"date-time":"2024-02-15T05:55:59Z","timestamp":1707976559000},"page":"1094","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Risk Factor Analysis of Complications and Mortality Following Coil Procedures in Patients with Intracranial Unruptured Aneurysms Using a Nationwide Health Insurance Database"],"prefix":"10.3390","volume":"13","author":[{"given":"So Yeon","family":"Park","sequence":"first","affiliation":[{"name":"Department of Medicine, College of Medicine, Yeungnam University, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"So An","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Medicine, College of Medicine, Yeungnam University, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu Hyeon","family":"An","sequence":"additional","affiliation":[{"name":"Department of Medicine, College of Medicine, Yeungnam University, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Won","family":"Kim","sequence":"additional","affiliation":[{"name":"Medical Research Center, College of Medicine, Yeungnam University, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saeyoon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, College of Medicine, Yeungnam University, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6822-1051","authenticated-orcid":false,"given":"Jae Min","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, College of Medicine, Yeungnam University, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youngjin","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Yeungnam University Medical Center, Daegu 42415, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.3171\/jns.1990.73.1.0037","article-title":"The International Cooperative Study on the Timing of Aneurysm Surgery.
