Purpose of this study is to assess the hypothesis that a strategy with acetylsalicylic acid (ASA) 100 mg/day, intensive blood pressure treatment (targeted systolic blood pressure below 120 mmHg), and a blood pressure measuring device reduces the risk of aneurysm rupture or growth compared with standard care (i.e. no ASA, blood pressure management according to standard blood pressure management, no blood pressure measuring device)

Condition Unruptured Intracranial Aneurysms
Treatment Acetylsalicylic acid, intensive blood pressure control
