Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients aged 18 and older admitted for poor grade aneurysmal subarachnoid hemorrhage classified as IV-V according to the WFNS classification.

Probably not a fit

Patients younger than 18, pregnant or breastfeeding women, and those with aneurysmal subarachnoid hemorrhage due to trauma or vascular malformations other than cerebral aneurysms may not benefit from this study.

What this trial studies

This multicentric registry aims to define outcomes, predictors, treatment effects, and modifiers in patients suffering from poor grade aneurysmal subarachnoid hemorrhage. The research focuses on three main areas: early brain injury predictors in the emergency department, delayed brain injury predictors in the neurocritical care unit, and treatment strategies. Additionally, it investigates the incidence and impact of delayed cerebral ischemia and the long-term follow-up of patients who may experience significant improvement after 6-12 months. Standard management will be provided according to established guidelines.

Why it matters

Potential benefit: If successful, this study could improve understanding of treatment outcomes and predictors, leading to better management strategies for patients with poor grade aneurysmal subarachnoid hemorrhage.

How similar studies have gone: Other studies have explored similar predictors and outcomes in subarachnoid hemorrhage, suggesting that this approach has potential for meaningful insights.
