Managing unruptured intracranial aneurysms with different treatment options

The Comprehensive Aneurysm Management Trial

Not applicable Interventional Centre hospitalier de l'Université de Montréal (CHUM) · NCT04155606

This study is testing whether surgery or a less invasive treatment is better for people with unruptured brain aneurysms compared to just monitoring their condition.

What this trial studies

This trial investigates the long-term clinical outcomes of patients with unruptured intracranial aneurysms (UIAs) who are offered either active treatment or conservative management. It aims to determine whether surgical clipping or endovascular treatment provides better outcomes compared to conservative management for patients deemed eligible for both surgical and endovascular options. The study addresses a significant gap in current medical practice, as there are no established guidelines or evidence supporting the treatment of UIAs. By offering a comprehensive framework for patient participation, the trial seeks to clarify the best management strategies for UIAs.

Who should consider this trial

Good fit: Ideal candidates include patients with at least one documented intracranial subarachnoid aneurysm who are considering treatment options.

Not a fit: Patients with recent intracranial hemorrhage or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this trial could provide evidence-based guidelines for the treatment of unruptured intracranial aneurysms, potentially improving patient outcomes.

How similar studies have performed: While there have been no randomized trials comparing active and conservative management for UIAs, the study addresses a critical need in the field, making it a novel approach.
