Research Areas

Mechanical Thrombectomy

The mechanical thrombectomy is a non-invasive procedure done in patients with acute onset of stroke. During this procedure a stent is advanced through a blot clot in the brain. Once the stent passes the clot it is pulled back in hopes to take the clot with it. This can be done with or without aspiration. 

Our Goal

To research and better characterize the use of mechanical thrombectomy as an effective treatment for patients with ischemic stroke. Including analyzing factors associated with reperfusion status after thrombectomy, different imaging modalities, TPA, event times, and functional outcomes.

Aneursym Coiling

Aneurysm Embolization

Cerebral aneurysms are enlargements of an artery that may be caused by weakening of artery walls. In order to treat these aneursyms, a non-invasive procedure can be conducted in which an embolization device is used to clot the localized enlargement. 

Our Goal

To research the effectiveness in technical, radiological, and clinical of many aneurysmal embolization devices. Some of these devices include: stent assisted coiling, Surpass Streamline Flow Diverter, Woven EndoBridge (WEB), and more.

Carotid Stenting/Angioplasty

In patients with Internal Carotid Artery occlusion or stenosis, carotid stenting/angioplasty (non-invasive) can be perform to recanalize the vessel and restore adequate blood flow to the brain.

Our Goal

To investigate and analyze the technical and clinical outcomes after endovascular treatment of patients with carotid artery stenosis and occlusion.

CVST

Cerebral Venous Sinus Thrombosis (CVST)

CVST is a rare form of stroke , commonly seen in young adults and children. It occurs when a blood clot forms in the venous system of the brain resulting in abnormal drainage and/or bleeding in the brain tissue.

Our Goal

To investigate risk factors and novel biomarkers using Machine Learning Methodologies (MLM), and to develop a prognostic to identifying high-risk individuals with CVST.  

Arteriovenous Malformation (AVM)

AVM's are unique entanglements of blood vessels that may connect arteries and veins together. This can disrupt normal blood flow as well as needed oxygen circulation. The vessels can also rupture and cause a bleed in the brain or spinal cord. Typical treatment includes non-invasive catheter or radiation therapy to close off these vessels. 

Our Goal

We focus on retrospectively studying AVM cases to develop new ways to better manage and treat these patients.

CTP

Cerebrovascular Imaging

We study cutting-edge innovative imaging modalities using research software for Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Computed Tomography Perfusion (CTP) modalities to devise novel approaches for the diagnosis, prognostication, and treatment for patients with ischemic and hemorrhagic strokes. The core lab is equipped with image acquisition and optimizing protocols for clinical and experimental studies. We use algorithms and machine learning applications to evaluate biomarkers for functional and structural cerebrovascular diseases.
