About this study
Official title: A Safety and Feasibility Study of the Use of Cervical Spinal Cord Stimulation for Treatment of Cerebral Vasospasm in Patients With Aneurysmal Subarachnoid Hemorrhage
The study is a non-blinded evaluation of the use of cervical spinal cord stimulation (SCS) for treatment of patients with Hunt and Hess grade 1-2 subarachnoid hemorrhage and evidence of cerebral vasospasm.
Read the detailed description
The study is a non-blinded evaluation of the use of cervical spinal cord stimulation (SCS) for treatment of patients with Hunt and Hess grade 1-2 subarachnoid hemorrhage and evidence of cerebral vasospasm. Stimulation will be provided with electrodes placed percutaneously in the upper cervical epidural space. The outcome of 5 patients will be studied with focus on possible adverse events related to the intervention. Vasospasm response to treatment will be measured as a secondary outcome. Middle cerebral artery flow velocity will be followed by transcranial Doppler and clinical outcome measured by NIH stroke scale. Flow velocities will be monitored daily by transcranial Doppler and NIH stroke scale performed daily for 7 days, after which spinal cord stimulation will be discontinued and the epidural lead removed.

Questions about this trial
What is this clinical trial studying?
A study testing Spinal Cord Stimulation in people with Cerebral Vasospasm, run by Mayo Clinic.
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 5 inclusion and 8 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The record says: withdrawn, as of the sponsor's last update on 22 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
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?
The study was withdrawn before enrolling participants, so there are no results.
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?
Looking at number of patients without an adverse effect (time frame: 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02426827, which also lists 10 linked publications.
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 22 Mar 2018.
