Vascular Neurology - Stroke Clinic

The Division of Vascular Neurology evaluates, treats and studies diseases which affect the structure and function of the blood vessels supplying the brain. The academic mission is two-fold: (1) to represent the principal educators of cerebrovascular disease for the Yale School of Medicine, the Yale Neurology Residency Program, and practitioners throughout New England; and (2) to investigate novel translational approaches to more effective acute stroke treatments, better secondary stroke prevention strategies and to improve stroke recovery and rehabilitation.

Vascular Neurologists hold teaching appointments at the Yale University School of Medicine and are clinical faculty within Yale Medical Group. They provide outpatient consultations in a multidisciplinary setting at the Yale Physician's Building or at the VAMC in West Haven, CT. Consultative services are also provided at Gaylord Hospital, one of the major rehabilitation hospitals in Connecticut. Yale conducts numerous acute and secondary stroke prevention clinical research trials including those sponsored by industry and the National Institutes of Health.

The stroke program was certified as a Primary Stroke Center by the Joint Commission in 2005 and by the Connecticut Department of Public Health in 2008. Its mission is to provide safe, effective, patient-centered, timely efficient and equitable care to patients with cerebrovascular disease at Yale-New Haven Hospital. The Stroke Center serves as a primary referral center for acute stroke management and has multidisciplinary outpatient stroke clinics for secondary stroke prevention and stroke recovery.

Joseph Schindler, MD serves as the Clinical Director of the Yale-New Haven Stroke Center and leads the acute stroke team activities. The hospital's resident-staffed acute stroke team is available 24/7 and in collaboration with clinical staff from neurosurgery, neuroradiology and emergency medicine, provide acute stroke consultation, treatment and cutting-edge interventional treatment aided by state-of-the-art imaging.

Yale-New Haven Hospital is the only hospital in Connecticut to offer acute vascular neurology consultation through the Yale-New Haven Telestroke Network. Now in its fourth year of operation, the Network allows a team of neurologists to provide 24/7 telemedicine coverage to two outlying hospitals in Connecticut and work in collaboration with the clinical staff in the Emergency Department to evaluate and treat patients presenting with acute neurological emergencies. These patients are also offered the opportunity to be transferred to Yale-New Haven Hospital for Neuro-interventional procedures, monitoring in the Neuro-Intensive Care Unit and enrollment in clinical trials.

Telestroke Network

In 2008, Yale-New Haven Stroke Center established Connecticut's first telemedicine — or telestroke program. Under the leadership of Joseph Schindler, MD, neurologists use a video and image-sharing telecommunications system to provide acute stroke care consultative services to outlying hospitals when patients present with acute stroke symptoms. Within minutes of making an initial call to Yale's telestroke network, the on-call neurologist can examine a patient at the remote hospital to help diagnose and make recommendations for treatment. This service offers selected patients the opportunity for treatment with IV tPA and for transfer to YNHH for neuro-interventional procedures.

YNHH has partnered with Lawrence and Memorial Hospital (New London, CT), Sharon Hospital (Sharon, CT) and Griffin Hospital (Derby, CT) to deliver acute stroke consultative services on a 24/7 basis. In addition, monthly teleconferencing meetings are held to review cases and to stay updated on the latest research  and evidence-based guidelines for acute stroke care. Hospitals within the telestroke network are certified as Primary Stroke Centers by either the CT Department of Health and/or the Joint Commission.

Telestroke programs throughout the country have demonstrated that telemedicine conferencing between outlying hospitals and trained stroke neurologists can enhance the use of tPA at hospitals that do not have on-site neurologists 24/7. Data analyzed from services rendered to our remote hospital showed a 90% increase in the rate of IV tPA administration and a reduction in the rate of symptomatic hemorrhage when comparing services pre and post telestroke (International Stroke Conference 2011).

Telestroke impact on patient care

A Stroke Story: David Schrage, a physically fit, 51-year-old tri-athlete, suffered a devastating stroke one afternoon at the office. Through video communication, drug therapy and cutting-edge neurosurgery at Yale-New Haven Hospital, Schrage was on the road to recovery within days (click to watch video).

The following clinical trials related to stroke at Yale-New Haven Hospital are currently undergoing relating to stroke at Yale-New Have Hospital. If you are interested in participating in any of these trials, please follow the links below. For ALIAS2 and CLEAR III, the patient must either be in the Emergency Room or admitted to the hospital with a new stroke.
