About the trial
What the trial wants to find out
A research-initiated prospective cohort study with the aim to assess the effectivity, safety and long-term outcomes after surgical and endovascular treatment of unruptured intracranial aneurysms. All consecutive patients with a non-ruptured intracranial aneurysms treated at Helsinki University Hospital will be included. Safety is measured by postoperative magnetic resonance imaging (MRI) taken 1-3 days after the treatment, treatment-related complications and functional outcome at three months. Effectiveness is measured by angiographic results and assessment of long-term bleeding from the treated aneurysm. Other outcomes include risk of developing epilepsy, getting a new stroke, and dementia on long-term follow-up.
The 2 groups in the trial
- Endovascular treatment
Patients with unruptured intracranial aneurysms treated endovascularly
