We aimed to investigate the effect of routine extradural anterior clinoidectomy (EAC) and extradural lamina terminalis fenestration (ELTF) on the incidence of shunt-dependent hydrocephalus (SDH) and gyrus rectus injury in patients undergoing microsurgical clip reconstruction. Methods: This matched case\u2013control study included 15 patients treated with routine EAC\/ELTF between July 2023 and June 2025, matched 1:2 to 30 historical controls (2000\u20132019) by aneurysm size, location, dome-to-neck ratio, and rupture status. The primary outcome was the incidence of SDH. The secondary outcomes included the incidence of gyrus rectus hypodensity\/injury and clinical outcomes, as assessed by the modified Rankin Scale (mRS) at discharge and follow-up. Results: Among 15 cases, 6 had ruptured aneurysms, 4 had unruptured aneurysms, and 5 were recanalized post-endovascular treatment. EAC was performed in all cases; ELTF was performed in 83% of ruptured cases. SDH occurred in 33% of ruptured cases versus 90% in controls (p = 0.02). Gyrus rectus hypodensity occurred in 13% of cases vs. 50% of controls (p = 0.01). EAC\/ELTF was associated with reduced odds of SDH (OR: 0.06; 95% CI: 0.004\u20130.80; p = 0.03) and gyrus rectus hypodensity (OR: 0.15; 95% CI: 0.03\u20130.80; p = 0.03). A poor outcome (mRS &gt;2) was seen in 27% at discharge, improving to 14% at follow-up (with a median of 11 months). Delayed cerebral ischemia occurred in 33% of ruptured cases. Conclusions: Routine EAC\/ELTF may reduce SDH and gyrus rectus injury after AComA aneurysm clip reconstruction, particularly in ruptured cases. Prospective multi-center studies are needed to validate these preliminary findings.<\/jats:p>","DOI":"10.3390\/jcm14207413","type":"journal-article","created":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T15:20:12Z","timestamp":1760973612000},"page":"7413","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preliminary Experience with Extradural Clinoidectomy and Lamina Terminalis Fenestration in Anterior Communicating Artery Aneurysm Surgery: A Matched Case\u2013Control Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8323-3778","authenticated-orcid":false,"given":"Yasmin","family":"Sadigh","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Erasmus MC Stroke Center, Erasmus MC University Medical Center, 3015 GD Rotterdam, The Netherlands"},{"name":"Center for Complex Microvascular Surgery, Erasmus MC University Medical Center, 3015 GD Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joost W.","family":"Schouten","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Erasmus MC Stroke Center, Erasmus MC University Medical Center, 3015 GD Rotterdam, The Netherlands"},{"name":"Center for Complex Microvascular Surgery, Erasmus MC University Medical Center, 3015 GD Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erik H.
