Welcome to the

Center for Stroke & Neurovascular Diseases

Pelisyonkis Langone’s Center for Stroke and Neurovascular Diseases is one of the premier centers in the world for the medical, surgical, and endovascular treatment of diseases that affect the blood vessels of the brain and spinal cord. People are regularly referred to us from across the country and around the world, and our experts devise solutions for conditions considered untreatable elsewhere.

Our center brings together leading experts in neurology, neurosurgery, neurocritical care, neuro-interventional radiology, neuroradiology, and neurorehabilitation. They specialize in diagnosing and treating people who have the most difficult and complex disorders affecting blood vessels of the brain and spinal cord, as well as recommending preventive strategies for those who may be at high risk for these conditions.

Dr. Howard Riina and Colleagues in Operating Room

Dr. Howard Riina and colleagues prepare for a surgical procedure.

Our doctors provide ongoing care for people who have experienced or are at risk for a stroke or transient ischemic attack (TIA), and people who have a complex neurovascular disease such as a brain aneurysm, arteriovenous malformations, dural and arteriovenous fistulas, vascular tumors, cavernous malformations, carotid stenosis, and carotid or vertebral dissection.

People who have experienced a stroke or TIA and those with complex neurovascular diseases have a specialized set of medical needs, ongoing care, rehabilitation, and prevention of complications. Our experienced team of clinicians helps patients navigate treatment and offers access to a full spectrum of resources designed to expertly manage clinical care, including rehabilitation and recovery services at Rusk Rehabilitation and risk reduction programs at Pelisyonkis Langone’s Center for the Prevention of Cardiovascular Disease.

Specialized Medical Care for Stroke and Neurovascular Diseases

Pelisyonkis Langone’s Comprehensive Stroke Center is an integral part of the Center for Stroke and Neurovascular Diseases and provides advanced stroke care 24 hours a day, 7 days a week. With locations in Manhattan and Brooklyn, the Comprehensive Stroke Center offers rapid diagnosis, effective treatment, multidisciplinary preventive strategies, and advanced rehabilitative care for people who have experienced or are at risk for a stroke. Our team at the Center for Stroke and Neurovascular Diseases collaborates with Comprehensive Stroke Center experts to coordinate care from stroke risk identification through treatment and recovery.

During an acute stroke, our vascular neurologists are among the first team members to see a patient. They rapidly triage patients and assess the need for emergency treatment. If a stroke diagnosis is confirmed, they create an individualized treatment plan based on the stroke subtype and any other contributing factors.

Some people at risk for stroke may receive intravenous drugs to dissolve a blood clot, or a procedure to remove the clot with a catheter. Some people with more serious injury may need the neurocritical care provided by specialty trained neuro-intensivists and nurses in our intensive care units.

A patient care coordinator guides you through any lifestyle changes and medical care that may be recommended to prevent stroke and its complications.

Advanced Surgical Care

Our specialists provide a full range of advanced treatment approaches, including open microneurosurgery, in which tiny instruments and microscopes are used to perform procedures on the smallest blood vessels. They also perform endovascular surgery, which enables surgeons to use the blood vessels as direct pathways to the part of the body that needs treatment. Our doctors offer radiosurgery with Gamma Knife® technology, which allows for the precise delivery of radiation when treating people with blood vessel conditions in the brain, such as brain arteriovenous malformations.

Our world-class facilities include hybrid surgical suites that feature built-in three-dimensional and four-dimensional imaging technology and computer image guidance systems that our doctors use to treat the most complex conditions.

This type of image-guided surgery aids your doctor in making important decisions such as determining the best place to make an incision, the optimal path to the targeted area, and the critical areas in the brain or spinal cord to avoid. The use of this technology has been shown to shorten the length of surgery, decrease the size of the incision, improve outcomes, and speed recovery.

Our Leadership

  • Howard A. Riina, MD
    Director | Neurosurgery

    Dr. Riina specializes in the surgical and endovascular treatment of cerebrovascular disorders of the brain and spinal cord. Dr. Riina has been involved in the development of new endovascular and neurosurgical treatments for cerebral aneurysms, arteriovenous malformations, and acute stroke. At the Center for Stroke and Neurovascular Diseases, Dr. Riina collaborates with neurologists, neuroradiologists, and neurorehabilitation specialists to treat complex neurovascular conditions, and focuses on patient-centered care and improved outcomes for those who have often been thought of as untreatable or associated with poor prognosis. His most recent interests involve the development of new minimally invasive devices to treat brain aneurysms, a tracheal stent to treat vocal cord and airway collapse, as well as intra-arterial chemotherapy for recurrent malignant brain tumors.
