Preliminary Experience with Extradural Clinoidectomy and Lamina Terminalis Fenestration in Anterior Communicating Artery Aneurysm Surgery: A Matched Case-Control Study.

ABSTRACT: Background/Objectives: The anterior communicating artery (AcomA) is one of the most common sites of intracranial aneurysms. 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-control study included 15 patients treated with routine EAC/ELTF between July 2023 and June 2025, matched 1:2 to 30 historical controls (2000-2019) 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 ou
