About this study
Official title: Biological Markers of Vasospasm in Cerebral Spinal Fluid and Blood in Patients With Subarachnoid Hemorrhage
In this project we are collecting cerebrospinal fluid and blood from patients at Vanderbilt Medical Center who have a subarachnoid hemorrhage which has followed the rupture of a brain aneurysm. We then propose to study the cerebrospinal fluid using a novel microscopic laser directed mass spectrometric analysis (MALDI) available at Vanderbilt. The cerebrospinal fluid and blood will then be analysed for different biological markers, protein expression and gene expression. These markers will then be statistically correlated with clinical data including prediction of vasospasm, time to vasospasm and response to standard therapy.

In this project we are collecting cerebrospinal fluid and blood from patients at Vanderbilt Medical Center who have a subarachnoid hemorrhage which has followed the rupture of a brain aneurysm. We then propose to study the cerebrospinal fluid using a novel microscopic laser directed mass spectrometric analysis (MALDI) available at Vanderbilt. The cerebrospinal fluid and blood will then be analysed for different biological markers, protein expression and gene expression. These markers will then be statistically correlated with clinical data including prediction of vasospasm, time to vasospasm and response to standard therapy.
The goal of this study is to determine cerebrospinal fluid and serum markers which will be predictive of vasospasm. This in turn may lead to improved outcomes in this population of patients.
The data will be compared to excess cerebrospinal fluid collected from patients who are undergoing lumbar puncture in the Neurology Clinic or excess cerebrospinal fluid from patients undergoing cranial surgery for other causes like tumor excision.
For patients enrolled in the study, cerebrospinal fluid will be collected by either lumbar puncture or external ventricular catheter. Specimens will be collected immediately pre-operatively if an external ventricular drain is in place or intraoperatively if an external ventricular drain is not present. We will also collect cerebrospinal fluid post operatively after placement of an external ventricular drain regularly from the excess cerebrospinal fluid that has been collected in the drainage bag. CSF will be collected in a serial fashion at multiple time points: immediately post operatively, during vasospasm and before the external ventricular drain is removed.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

We then propose to study the cerebrospinal fluid using a novel microscopic laser directed mass spectrometric analysis (MALDI) available at Vanderbilt. The cerebrospinal fluid and blood will then be analysed for different biological markers, protein expression and gene expression.

Questions about this trial
What is this clinical trial studying?
An observational study of Subarachnoid Hemorrhage, run by Vanderbilt University Medical Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 27 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
correlate biological markers of cerebral vasospasm with clinical outcomes (time frame: post hemorrhage). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Mar 2026; AzTrials last refreshed its copy on 8 Nov 2026.
