Blood clue may reveal which brain aneurysms will burst

NCT ID NCT03408379

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether platelet activation in the blood is higher in people whose brain aneurysm has already burst compared to those with an unruptured aneurysm. Researchers will collect blood samples from 230 patients during treatment. The goal is to see if platelet activity could help predict rupture risk.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If this study finds a link, it could point toward new ways to predict which aneurysms might rupture.
What could go wrong
This is an observational study, not a treatment trial. It only looks for a connection, so it won't directly help patients yet.
