Cerebrovascular and Stroke Center

Our Center

The Stony Brook University Medical Center Cerebrovascular and Stroke Center has a dedicated team with the expertise needed to diagnose and treat a wide range of cerebrovascular diseases, including arteriovenous malformations, arteriovenous fistulas, hemorrhagic strokes, ischemic strokes, atherosclerosis, and carotid stenosis. We are a multidisciplinary team of neurologists, interventional neuroradiologists, and cerebrovascular neurosurgeons who are committed to excellence in patient care, research, and education.

The Cerebrovascular and Stroke Center is home to an active clinical trials unit supported by four clinical research coordinators and an NIH funded hemodynamics laboratory. The clinical and translational research is funded by more than two dozen research grants and we participate in virtually all of the major trials that are currently underway in the U.S. As a result our patients have access to a wide variety of devices that are currently experimental but are available on a "compassionate use" basis to patients who have otherwise untreatable conditions.

The Cerebrovascular and Stroke Center use a multidisciplinary, team-based approach, state-of-the-art facilities and equipment, and the latest surgical and minimally invasive techniques to accurately diagnose your cerebrovascular disorder and design a treatment plan that is individualized to your unique circumstances.

Stony Brook's state-of-the-art facilities, which include high-speed computed tomographic (CT), MRI, biplane angiography equipment and a new $14 million cerebrovascular biplane suite, enable us to make quick and accurate diagnoses so that critical treatment can begin as soon as possible.
