Subarachnoid Hemorrhage clinical trials at UCSF

4 in progress, 2 open to eligible people

Subarachnoid hemorrhage is bleeding between the brain and its covering membranes. UCSF is researching non-invasive methods to monitor brain pressure using ultrasound. UCSF also offers a registry that links stroke survivors with researchers studying recovery methods.

  • NOninVasive Intracranial PrEssure from Transcranial DoppLer Ultrasound Development of a Comprehensive Database of Multimodality Monitoring Signals for Brain-Injured Patients

    open to eligible people ages 18 years and up

    This is an observational study in neurocritical care units at University of California San Francisco Medical Center (UCSFMC), Zuckerberg San Francisco General Hospital (ZSFGH), UC Davis, and Emory University. In this study, the investigators will primarily use the monitor mode of the Transcranial Doppler (TCD, non-invasive FDA approved device) to record cerebral blood flow velocity (CBFV) signals from the Middle Cerebral Artery and Internal Carotid Artery. TCD data and intracranial pressure (ICP) data will be collected in the following four scenarios. Each recording is up to 60 minutes in length. Multimodality high-resolution physiological signals will be collected from brain injured patients: traumatic brain injury, subarachnoid and intracerebral hemorrhage, liver failure, and ischemic stroke. This is not a hypothesis-driven study but rather a signal database development project with a goal to collect multimodality brain monitoring data to support development and validation of algorithms that will be useful for future brain monitoring devices. In particular, the collected data will be used to support: Development and validation of noninvasive intracranial pressure (nICP) algorithms. Development and validation of continuous monitoring of neurovascular coupling state for brain injury patients Development and validation of noninvasive approaches of detecting elevated ICP state. Development and validation of approaches to determine most likely causes of ICP elevation. Development and validation of approaches to detect acute cerebral hemodynamic response to various neurovascular procedures.

  • Stroke Recovery Initiative - Registry for Stroke Research Studies

    open to eligible people ages 18 years and up

    The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.

  • IA Lidocaine and Methylprednisolone for Headache Associated With Subarachnoid Hemorrhage

    Sorry, not yet accepting patients

    Subarachnoid hemorrhage (SAH) is a type of bleeding around the brain that can cause sudden and severe headaches. These headaches can be debilitating and persist for weeks, significantly impacting a patient's comfort and recovery. Many patients require opioids for pain control, which can lead to side effects such as drowsiness, constipation, and dependency. There is a need for new treatment strategies to help relieve this pain while minimizing side effects. This clinical study is designed to evaluate whether an injection of two medications (lidocaine and methylprednisolone) directly into the middle meningeal artery (MMA) can help reduce headache severity in patients who recently experienced a SAH. The medications will be given through a minimally invasive procedure performed during a routine angiogram, a type of imaging test already commonly used in SAH patients. The main goals of the study are to determine whether this treatment approach is safe, helps to reduce the severity of headaches, and decreases the need for opioid pain medications. Eligible patients will be those recently diagnosed with persistent headache symptoms and SAH who are undergoing routine cerebral angiogram, during which the medications are infused into the MMA. Participants will be monitored for pain levels using the Headache Impact Test (HIT-6) and for changes in their functional recovery using standard neurologic scales. The results of this study may provide early evidence to support new treatment options for patients suffering from difficult-to-control headaches after a SAH.

  • GTX-104 Compared with Oral Nimodipine in Patients with ASAH

    Sorry, in progress, not accepting new patients

    The purpose of this study is to deliver nimodipine via IV directly into the bloodstream and to determine if this is as safe and tolerable as oral nimodipine capsules.
