Aim:To evaluate the patients who underwent surgery for an anterior communicating artery (AcomA) aneurysm at our institution. We analyzed our case series and systematically reviewed the literature to identify factors that could predict the rupture of an intracranial aneurysm in patients with AcomA aneurysms or any intracranial aneurysm.Material and Methods:We conducted a cross-sectional analysis of prospectively collected data from patients who underwent surgery for AcomA aneurysms at a single institution between January 2014 and May 2023. Predictors for the rupture of intracranial aneurysm were systematically reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Pubmed and MEDLINE databases.Results:Younger age (odds ratio (OR): 0.957, 95% confidence interval (CI): 0.920–0.995, p = 0.028), presence of a daughter sac (OR: 3.209, 95% CI: 1.095–9.408, p = 0.034), and ever-smoking (OR: 0.357, 95% CI: 0.137–0.930, p = 0.035) were significant predictors of increased risk of rupture in patients with AcomA aneurysms. Several aneurysm- and patient-related risk factors for rupture of intracranial aneurysms were retrieved via the literature analysis.Conclusion:Younger age, ever-smoking, and presence of a daughter sac increased the risk of AcomA aneurysm rupture. A systematic literature review revealed several more aneurysm- and patient-related risk factors for rupture of the intracranial aneurysms. Our results could aid neurosurgeons during their decision-making process when treating patients with unruptured intracranial aneurysms.
