A Comprehensive Stroke Center

Welcome to Westchester Medical Center (WMC), the flagship of Westchester Medical Center Health Network, and the only hospital in the Hudson Valley recognized as a Comprehensive Stroke Center. As a certified Comprehensive Stroke Center, we can receive patients from throughout the Hudson Valley and beyond via Life Flight air transport and support from our transfer center team. Our dedicated, 24/7 stroke team is always on call to provide life-saving neurological and neurosurgical care for patients experiencing acute stroke.

As the region’s leading stroke care providers, we are honored recipients of the American Heart Association/American Stroke Association's Get with the Guidelines® Stroke Gold Plus Quality Achievement Award for 2022. (Learn more.)

Our stroke care extends throughout the region through community hospitals that are designated primary stroke centers: Good Samaritan Hospital, MidHudson Regional Hospital and HealthAlliance Hospital.

What Is a Stroke?

Stroke is a medical emergency that can result in permanent neurological damage; complications such as pneumonia, brain swelling, seizures and blood clots; or death. It is a leading cause of long-term adult disability in the United States and the second leading cause of death globally. Risk factors for stroke include advanced age, hypertension, previous stroke or transient ischemic attack (TIA), diabetes, high cholesterol, cigarette smoking, and atrial fibrillation. High blood pressure is understood as the most important modifiable risk factor for stroke.

There are two main types of stroke: ischemic and hemorrhagic. Ischemic stroke is caused by a lack of blood flow to the brain, often due to blockages or arterial embolism. Hemorrhagic stroke is caused by bleeding in the brain. Both types of stroke can result in the loss of brain function, which may cause inability to move limbs on one side of the body, difficulty speaking or understanding speech, or loss of vision in one side of the visual field.

BEFAST: Remember the signs of a stroke

Rapid Assessment. Rapid Action.

From the moment EMS notifies our hospital of an incoming stroke patient, our stroke response activates. A 24/7 team of triage nurses, radiologists, neurologists, neurosurgeons and pharmacists prepare for the patient's arrival. Once a patient enters our doors, our multidisciplinary team begins performing a rapid assessment and evaluation of the patient's condition, administering appropriate treatments, and coordinating with other medical professionals as needed to provide the best possible care for the patient. The full team may include:

  • EMTs
  • Triage Nurses
  • Radiologists (and CT scan)
  • Pharmacists
  • Neurologists
  • Neurosurgeons
  • Residents, Stroke Attending, Emergency Department physicians, nurses and more

Clinical Research

Our neurologists are prolific researchers whose work is frequently published in academic medical journals. Our physicians and patients are involved in numerous clinical studies. Learn more about Stroke Clinical Research at Westchester Medical Center.

Stroke Treatment Options

Ischemic Stroke Treatment

Treatment for ischemic stroke may include intravenous thrombolysis (thrombolytic therapy). Alteplase or tenecteplase are drugs used to break up the clot. These drugs are commonly known as a "clot buster." In some patients, additional treatment is needed to remove the clot.

Westchester Medical Center and MidHudson Regional Hospital are unique as two of the few hospitals in the area with the trained surgeons and facilities needed for endovascular thrombectomy, another stroke treatment option in which a skilled neurosurgeon physically removes the clot. In a thrombectomy, the neurosurgeon inserts a catheter via a small incision, typically in the groin. Using real-time imaging technology, the neurosurgeon carefully guides the catheter through a network of blood vessels, arriving at the clot. Tiny surgical tools are then used to remove the clot. A small device may be permanently placed in the blood vessel to help it stay open and healthy. Surgeons may also perform carotid stenting and carotid endarterectomies in the treatment of ischemic stroke.

Hemorrhagic Stroke Treatment

Treatment for hemorrhagic stroke is also available at Westchester Medical Center. One type of hemorrhagic stroke is caused by a ruptured aneurysm. This is typically treated with an endovascular approach. One common approach is endovascular coiling, in which the surgeon introduces a coil made of metals like platinum to promote clotting and stabilization of the aneurysm.

In some cases, the surgeon may clip the aneurysm in an open craniotomy. Clipping an aneurysm refers to placing a permanent titanium clip on a section of the artery in order to prevent blood from entering the aneurysm, worsening the patient’s condition, and increasing risk of rupture.

Telestroke Program

Our Telestroke Program allows us to extend Westchester Medical Center’s expertise to community-based hospitals throughout the Hudson Valley. Physicians at neighboring facilities seeking telestroke support facilities can instantly alert WMC neurologists of a new stroke patient. Using technology that is quite similar to making a video call on your phone, our neurologist can conduct a comprehensive stroke exam in real-time with the patient. This evaluation may help the patient receive local care or may indicate a need for the patient to be immediately transported to Westchester Medical Center for more complex acute care.

Revolutionary Diagnostic Technology for Heart Complications

WMC is the only facility in the region to have robotic TCD (transcranial doppler) imaging technology. This advanced imaging technology allows neurologists to perform a diagnostic test that may reveal if a patient has patent foramen ovale (PFO), a very common congenital heart condition characterized by a hole in the heart. PFO may be the cause of stroke in some patients. If PFO is discovered after the initial stroke has been treated, then the neurologist may recommend closure of this hole to reduce potential risk of future stroke. Many of these closures are performed at Westchester Medical Center.

Stroke Recovery and Follow-Up Care

Stroke rehabilitation can help restore lost function. Rehab typically involves speech and language therapy, physical therapy, and occupational therapy. 

To prevent recurrence of a stroke, patients may be given antiplatelet drugs such as aspirin and dipyridamole, and may be treated for hypertension and high cholesterol. In some cases, carotid endarterectomy and anticoagulant medication may also be beneficial.

The Stroke Rehabilitation Program at Westchester Medical Center uses advanced technologies to promote recovery, including virtual reality and exoskeleton suits that provide support to survivors as they relearn balance and walking skills.
