Summary

This trial is a is a prospective, randomized (1:1) placebo-controlled, clinical trial with blinded endpoint assessment of 440 participants with unruptured brain aneurysm planned for endovascular treatment using coiling-only approach (primary coiling or using balloon-assistance but not stenting) to test if oral acetylsalicylic acid (325 mg/ day for a total of 5 days) is superior placebo in preventing clinical and silent strokes.
