• Study Focus: Management of unruptured intracranial aneurysms (UIAs) from conservative to interventional.
• Objective: Identify patterns and predictors for revising UIA management strategy.
• Methodology: Retrospective review of cases diagnosed between 2006-2022 with conservative management.
• Results: 10 of 144 cases shifted to interventional treatment due to aneurysm growth.
• UIA Growth: Most frequent reason for changing treatment strategy.
• Size Threshold: UIAs > 3 mm at diagnosis more likely to require intervention.
• Conservative Management: Regular radiographic follow-ups recommended, especially for UIAs > 3 mm.
• Guidelines: ESO and American Heart Association guidelines emphasize monitoring UIA growth.
• Statistical Analysis: Cox regression and Kaplan-Meier curves used for data analysis.
• Risk Factors: No significant effect of potential risk factors on treatment change.
• Imaging: DSA as confirmative modality for revising conservative management.
• Study Limitations: Low statistical power due to limited cases of treatment change.
• Conclusion: Regular monitoring crucial for conservatively managed UIAs, especially > 3 mm.
