Neurovascular Stroke Center

Stroke is a medical emergency. Receiving appropriate treatment could significantly reduce long-term disability. In order to receive timely evaluation and treatment, it is imperative that stroke victims get to the hospital as soon as they experience symptoms suggestive of stroke. Treatment within eight hours of symptom onset at a hospital with a specialized stroke team provides the best chance in minimizing the long-term effects of stroke.

The Ohio State University Neurovascular Stroke Center offers quality around-the-clock assessment and treatment by experienced medical professionals specialized in stroke care. Our team of stroke experts is available 24/7 to stroke victims in metro Columbus area and the surrounding counties in central Ohio. The OSU Stroke Center is accredited by the Joint Commission on Accreditation of Healthcare Organizations (TJC), reflecting our commitment to the highest quality of care and safety. The OSU Stroke Center is the recipient of the 2011 Stroke Care Excellence Award™ and the 2012 America’s 100 Best Stroke Care™ hospitals by HealthGrades®.

The OSU Stroke Center is staffed and operated by physician faculty from OSU Departments of Neurology and Neurological Surgery. We have around-the-clock and immediate access to sophisticated neuro-imaging modalities such as emergent MR diffusion/perfusion and CT perfusion scans. In addition to intravenous thrombolysis (IV rtPA), the OSU Stroke Center offers interventional reperfusion therapies for acute ischemic stroke, including administration of intra-arterial rtPA and mechanical embolectomy. We also have full capability to provide appropriate and timely care for patients with hemorrhagic stroke.

As a part of our commitment to high quality stroke care to underserved areas, we have developed a signature collaboration with several hospitals in rural central Ohio via Telemedicine technology. This real-time remote video technology brings academic neurovascular expertise to underserved regions and enables timely delivery of thrombolytic therapy under the supervision of an OSU vascular neurologist. The faculty physicians of the Stroke Center are also available through telephone consultations with the outside healthcare facilities.Our outpatient cerebrovascular clinics are staffed by expert physicians specifically focusing on the needs of patients with ischemic and hemorrhagic strokes, arteriovenous malformations, cerebral aneurysms, and other disorders of brain and spinal cord vasculature.
Delivering quality care is also one of the reasons OSU Medical Center’s Neurology and Neurosurgery programs are ranked by U.S. News & World Report as “America’s Best.” Our stroke rehabilitation program at OSU Dodd Hall is also consistently ranked among the top ten stroke rehabilitation centers in the country.
