5,000 patients enrolled to build brain bleed prediction tool
NCT ID NCT05738083
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is tracking 5,000 people who had a brain bleed from a ruptured aneurysm. Researchers are collecting medical data to find factors that predict complications like delayed brain injury or long-term disability. The goal is to create a computer model that helps doctors forecast recovery and make better treatment decisions.
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 successful, this could lead to better prediction tools for doctors to identify which patients are at higher risk for complications or poor recovery after a brain bleed.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly improve patient outcomes. The prediction models may not work well in other hospitals or countries.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Subarachnoid hemorrhage confirmed by computed tomography (CT); * Cerebral angiography (CTA) and digital subtraction angiography (DSA) examination confirming intracranial aneurysm rupture as the cause of the subarachnoid hemorrhage; * Blood routine, biochemical function, blood coagulation function, and craniocerebral CT performed within 24 hours of symptom onset; * Underwent aneurysm clipping by surgery or endovascular embolization within 72 hours after-onset. Exclusion Criteria: * Aneurysm rupture bleeding time exceeding 24 hours before hospital admission; * Incomplete image data or blood test information; * Long-term use of anticoagulant medications such as aspirin or warfarin; * Admitted to hospital with active infectious diseases; * long-term anticoagulant drugs such as aspirin, wave dimensions; * Presence of other intracranial vascular malformations.
