Permanent Cerebral Oxymetry Monitoring for Early Diagnosis and Treatment of Delayed Vasospasm After Subarachnoid Hemorrhage (COMOVA)

Transcranial Doppler ultrasound (TCD) monitoring and CT-scanner perfusion are useful but imperfect tools to identify vasospasm and allow intervention to avoid infarction. Permanent

GLP-1 Analogue in Preventing Progression of Small Vessel Disease (GAPP-SVD) (GAPP-SVD)

Cerebral small vessel disease (cSVD), a result of neurovascular cell dysfunction, is a major cause of stroke, dementia and mobility problems worldwide. Vascular risk factor control alone may not be sufficient to prevent the development of vascular cognitive impairment (VCI) in patients with cSVD according to previous clinical trials. The …

Evaluation of Cerebrovascular Events in Patients With Occlusive Carotid Artery Disorders

As of today, no suitable multiparametric predictive method is available to properly estimate stroke risk in patients with carotid artery stenosis. Carotid artery stenosis is one of the proven risk factors of stroke incidence, but the indication of its intervention is merely the grade of stenosis itself. The current international …

Estimation of Intracranial Pressure Using Non-invasive Fundus Videos

The purpose of this pilot study is to assess whether the intracranial pressure (ICP) can be detected by using a non-invasive retinal fundus scanner, recording the vessels of the eye entering from the optic disc. The artery's diameter (A) is measured and compared to the vein's diameter (V) thereby a …

Perioperative Cerebrovascular Autoregulation Monitoring in Neurosurgical Patients

One of the challenges in pediatric anesthesiology is to ensure adequate cerebral perfusion pressure to prevent cerebral ischemia or hyperemia from pressure-passive perfusion. However, there is no optimal tool for longitudinally monitoring cerebral perfusion under general anesthesia (GA). In addition, the safe limits of blood pressure that maintains adequate cerebral …

NOninVasive Intracranial prEssure From Transcranial doppLer Ultrasound Development of a Comprehensive Database of Multimodality Monitoring Signals for Brain-Injured Patients (NOVEL ICP)

This is an observational study in neurocritical care units at University of California San Francisco Medical Center (UCSFMC), Zuckerberg San Francisco General Hospital (ZSFGH), and Duke University Medical Center. In this study, the investigators will primarily use the monitor mode of the Transcranial Doppler (TCD, non-invasive FDA approved device) to …
