About Our Research Programs

The Comprehensive Cerebrovascular and Stroke Center of USC is a leader in research, attracting students, residents and fellows to participate in groundbreaking clinical trials and research projects. Our research includes prehospital stroke studies, acute stroke research, as well as stroke prevention and recovery after stroke.

Current Research

Defuse 3

This is a study to evaluate the hypothesis that FDA cleared thrombectomy devices plus medical management leads to superior clinical outcomes in acute ischemic stroke patients at 90 days when compared to medical management alone in appropriately selected subjects with the Target mismatch profile and an MCA (M1 segment) or ICA occlusion who can be randomized and have endovascular treatment initiated between 6-16 hours after last seen well.

  • Primary: To test the hypothesis that apixaban is superior to aspirin for the prevention of recurrent stroke in patients with cryptogenic ischemic stroke and atrial cardiopathy.
  • Secondary: To test the hypothesis that the relative efficacy of apixaban over aspirin increases with the severity of atrial cardiopathy.

Crest – H

We aim to determine whether cognitive impairment attributable to cerebral hemodynamic impairment in patients with high-grade asymptomatic carotid artery stenosis is reversible with restoration of flow. To accomplish this aim CREST-H will add on to the NINDS-sponsored CREST-2 trial (parallel, outcome-blinded Phase 3 clinical trials for patients with asymptomatic high-grade carotid artery stenosis which will compare carotid endarterectomy plus intensive medical management (IMM) versus IMM alone (n=1,240), and carotid artery stenting plus IMM versus IMM alone (n=1,240) to prevent stroke and death).

The purpose of this study is to test a newly-developed outpatient clinic and community-based care intervention called SUCCEED (Secondary stroke prevention by Uniting Community and Chronic care model teams Early to End Disparities) for improving control of stroke risk factors among stroke patients in the Los Angeles County “safety net”, and to measure the costs of running such an intervention, relative to usual care.

The purpose of this study is to test a newly developed outpatient care intervention called SUSTAIN (Systematic Use of Stroke Averting Interventions) for improving delivery of stroke preventive services at Los Angeles County hospitals and to measure the costs of running such an intervention.

The purpose of this study is to determine the effects of the Doctormate device, a specialized blood pressure cuff used to perform remote limb ischemic conditioning, on cerebral blood flow in subjects with intracranial atherosclerosis. Previous studies in patients with narrowing of the brain arteries have shown that this device is safe to use and suggested that if this device is inflated in both arms for 5 minutes, followed by deflation for 5 minutes and repeated 4 times in a row every day for 6-9 months, the risk of another stroke is lowered and the device may increase the blood flow to the brain.

Featured Publication

DEFUSE 3 is an NIH-funded trial, testing the safety and efficacy of mechanical thrombectomy plus medical management, compared with medical management alone for six to 16 hours after a large artery ischemic stroke. Perfusion CT and/or advanced MR imaging will be used to identify candidates for this trial. Keck Medicine of USC is the only trial site in Los Angeles. [NCT02586415]
