Abstract: BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are commonly prescribed for the management of type 2 diabetes, and recent studies have highlighted their neuroprotective and anti-inflammatory properties. However, their influence on clinical outcomes in patients undergoing endovascular treatment for unruptured intracranial aneurysms remains largely unexplored. METHODS: : I67.1). Patients were categorized based on the use of GLP-1RAs. The outcomes included overall survival, poor functional outcome, new subarachnoid hemorrhage, and hydrocephalus. The propensity score matching method was applied. RESULTS: A total of 6824 patients met the inclusion criteria, with 447 patients in each group following propensity score matching. No statistically significant differences were observed in short- and mid-term mortality between GLP-1RAs users and non-users. However, long-term mortality was significantly lower in the GLP-1 group (odds ratio 0.58, 95% CI 0.36-0.94). Furthermore, GLP-1RAs users demonstrated significantly reduced risks of poor functional outcomes (odds ratio 0.37, 95% CI 0.21-0.66), new subarachnoid hemorrhage (odds ratio 0.39, 95% CI 0.27-0.56), and hydrocephalus (odds ratio 0.57, 95% CI 0.33-0.97) at 3 months, with similar trends persisting in mid- and long-term follow-up. CONCLUSION: Use of GLP-1RAs in patients with unruptured intracranial aneurysms treated via endovascular intervention is associated with improved long-term survival and reduced risks of subarachnoid hemorrhage, hydrocephalus, and poor functional outcomes. These findings suggest a potential therapeutic benefit beyond glycemic control. Prospective studies are needed to validate these results and explore their implications for clinical decision-making in aneurysm treatment.
