Endovascular treatment (EVT) has become a preferred approach, but optimal management strategies remain debated. This study compares the efficacy and safety of different EVT techniques, including primary coiling, stent-assisted coiling (SAC), and flow diversion (FD), in treating AChoA aneurysms.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Patients were categorized by endovascular technique, aneurysm morphology, and rupture status. Angiographic occlusion rates were assessed using the Raymond-Roy Occlusion Scale (RROS), and clinical outcomes were measured via the Modified Rankin Scale (mRS) at discharge and follow-ups. Statistical analyses compared occlusion rates, procedural complications, and functional outcomes among treatment groups.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>In this study, 60 patients with 80 anterior choroidal artery aneurysms were treated. Among these, 44 aneurysms (55%) were classified as dependent, meaning the choroidal branch arose from the aneurysm dome or neck, while 36 aneurysms (45%) were independent, originating from the carotid artery near the choroidal branch. Primary coiling was used in 29 cases, stent-assisted coiling (SAC) in 21, and flow diversion (FD), with or without additional coiling, in 30 cases. Complete occlusion rates were significantly higher with SAC (83.3%) and FD (76.1%) compared to primary coiling (31.8%) (p\u2009&lt;\u20090.05). Flow diversion was associated with more technical complications (25%), and ischemic events were more common in dependent aneurysms (p\u2009&lt;\u20090.05). Importantly, no cases of symptomatic AChoA occlusion occurred after FD treatment. The overall mortality rate was 5%, with all deaths occurring in the primary coiling group among patients with ruptured aneurysms.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>EVT of AChoA aneurysms is effective, with SAC and FD demonstrating superior occlusion rates compared to primary coiling. FD carries a higher risk of technical complications but maintains AChoA patency. To optimize outcomes, treatment choice should be guided by aneurysm morphology and patient risk factors.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s00701-025-06647-9","type":"journal-article","created":{"date-parts":[[2025,9,1]],"date-time":"2025-09-01T07:39:19Z","timestamp":1756712359000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative analysis of endovascular treatment methods for anterior choroidal aneurysms: single center study with 80 aneurysms"],"prefix":"10.1007","volume":"167","author":[{"given":"Yigit Can","family":"Senol","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Halis Emre","family":"Ciftci","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zeynep Gence","family":"Oz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dilara","family":"Duman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bige","family":"Sayin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilkay","family":"Akmangit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Musa Onur","family":"Ozbakir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denizhan","family":"Divanlioglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmet Deniz","family":"Belen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ergun","family":"Daglioglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,9,1]]},"reference":[{"issue":"1","key":"6647_CR1","doi-asserted-by":"publisher","first-page":"127","DOI":"10.3171\/2024.4.JNS24362","volume":"142","author":"P Barhouse","year":"2025","unstructured":"Barhouse P, Young M, Taussky P, Pacheco-Barrios N, Ogilvy CS (2025) Anterior choroidal artery aneurysms: a systematic review and meta-analysis of outcomes and ischemic complications following surgical and endovascular treatment.
