Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with acute, spontaneous, primary supratentorial intracerebral hemorrhage greater than 20 mL and who can undergo surgery within 24 hours of symptom onset.

Probably not a fit

Patients with underlying vascular lesions, profound neurological deficits, or those with infratentorial hemorrhages may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This registry focuses on the use of the Aurora® Surgiscope to facilitate minimally invasive surgical access and visualization for the removal of hematomas in the brain. It will evaluate various methods of hematoma removal based on surgeon preference and assess the impact of patient selection and timing of surgery from the last known well time. The study aims to gather data on outcomes related to this innovative surgical approach.

Why it matters

Potential benefit: If successful, this could lead to improved surgical outcomes and recovery for patients with acute supratentorial hemorrhages.

How similar studies have gone: While this approach is innovative, similar minimally invasive techniques have shown promise in other studies, suggesting potential for success.
