Because of the coagulopathy, simple internal carotid artery ligation was chosen, and the aneurysm initially shrank following treatment. However, it recurred due to collateral arteries from the posterior communicating artery and branches of the external carotid artery. These arteries were occluded using endovascular techniques, resulting in complete obliteration of the aneurysm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>To the best of the authors\u2019 knowledge, this is the first reported case of treating a giant CCA associated with hemophilia A. In patients with coagulopathy, surgical options are limited, and standard treatments may not achieve a complete cure. Careful consideration of treatment strategies is crucial when managing giant CCA in the context of a coagulation disorder.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE24693\">https:\/\/thejns.org\/doi\/10.3171\/CASE24693<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case24693","type":"journal-article","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T02:57:07Z","timestamp":1740365827000},"source":"Crossref","is-referenced-by-count":0,"title":["Challenges in the treatment of giant cavernous carotid aneurysm associated with hemophilia A: illustrative case"],"prefix":"10.3171","volume":"9","author":[{"given":"Yuichi","family":"Hirata","sequence":"first","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1054-0612","authenticated-orcid":true,"given":"Masafumi","family":"Hiramatsu","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Sugiu","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juntaro","family":"Fujita","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuta","family":"Sotome","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3277-6434","authenticated-orcid":true,"given":"Masato","family":"Kawakami","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9699-916X","authenticated-orcid":true,"given":"Ryu","family":"Kimura","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Ebisudani","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1009-6216","authenticated-orcid":true,"given":"Jun","family":"Haruma","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shota","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"bib1","article-title":"World Federation of Hemophilia Report on the Annual Global Survey 2022.","unstructured":"1.World Federation of Hemophilia.
