Stroke

Miami Cardiac & Vascular Institute provides comprehensive stroke treatment services and treatments. About 800,000 people in the United States experience a stroke every year, according to the American Heart Association. Stroke is the fourth leading cause of death.

Our physicians work with you to help you manage and treat the disease before it has serious consequences. Our goal is to improve your health and quality of life.

Types of Stroke

An ischemic stroke occurs when there is a lack of blood flow into the brain. The effects of a stroke can be minimal, severe, temporary or permanent, depending on the location where the brain had damage.

An embolic stroke occurs when a blood clot is created somewhere in your body, usually within the heart, and travels through the bloodstream into your brain. Once it reaches your brain, it then blocks your blood vessels, causing a stroke.

A thrombotic stroke occurs when blood vessels are unhealthy and build fatty deposits or cholesterol in the wall of the artery, blocking blood flow to your brain.

A hemorrhagic stroke occurs when there is too much blood flow into the brain. An intracerebral hemorrhagic stroke occurs when the blood vessels within the brain bleed, and is usually caused by high blood pressure. A subarachnoid hemorrhagic stroke occurs when an aneurysm bursts, bleeding into the space between the brain and the skull.

Treatment Options


Stroke Team. Because time is critical with stroke care, the multidisciplinary stroke team at Baptist Health Neuroscience Center goes into action when paramedics notify us that a stroke patient is en route to one of our emergency rooms.

The Institute offers the following stroke treatments:

tPA Clot-busting Medication. If diagnostic tests reveal your stroke is caused by a blood clot, physicians can administer tissue plasminogen activator (tPA), a commonly used clot-busting drug. tPA is most effective when given within a certain time of onset of stroke symptoms, again emphasizing the need for fast treatment.

Carotid artery stenting. An interventional radiologist performs this minimally invasive procedure under local anesthesia by threading a small catheter through a blood vessel in your groin. Once the catheter reaches your carotid artery, a removable protection device deploys inside the artery to capture any plaque that could loosen and cause a stroke. Next, the doctor places a mesh-like metal device called a stent in the narrowed portion of the artery. The stent is designed to keep the artery open and restore blood flow to the brain.

Flow Diverter. A flow diverter is a device that can reroute blood flow around an intracranial aneurysm ¬– a weakened, bulging part of an artery that carries blood to the brain. A flow diverter is essentially a long stent with a denser mesh. The flow diverter is placed endovascularly (inside the vessel) and supports the artery while also helping to close off blood flow to the aneurysm.

Coiling. Coiling uses a tiny spring-shaped device to block the blood flow into a weakened, bulging part of a brain artery called an aneurysm. The goal is to keep the bulging area from bursting and causing a stroke. Sometimes coiling can also be used after an aneurysm has broken open. The coiling procedure is endovascular (inside the vessel) so no surgery is required. An interventional neuroradiologist places a catheter through the artery in your groin and directs the coiling device up to the aneurysm site in your brain.

Surgical Clipping. Surgery that places a clip to close off a brain aneurysm is called surgical clipping. The clips shut off blood flow to a bulging, weakened portion of a brain artery. The goal is to prevent the aneurysm from bursting open and causing a stroke. The clips are placed in the brain permanently.

Clot Extraction Device. Institute physicians can also remove blood clots from blockages in brain arteries using new-generation retrieval devices. This is an endovascular (inside the vessel) treatment for patients experiencing an ischemic stroke. Physicians use a catheter (a thin tube) to guide the device into the affected area. The extractor compresses and withdraws the clot to restore blood flow to the brain.

Stroke
Stroke is a serious condition that requires clinical care by a physician or other healthcare professional. Listed in the directory below you will find some additional information regarding stroke, for which we have provided a brief overview.

​​

To help in the diagnosis of your stroke, your physician may request that you have one or more of the following tests:

  • Ultrasound
  • Carotid Doppler
  • Transcranial Doppler
  • Cerebral angiography
  • MRI
  • Magnetic resonance angiography (MRA)
  • CT scans
  • CT angiograms (CTA)
  • Echocardiography​​

As a leader in neurologic and vascular care, the Institute conducts clinical trials to explore new interventions to prevent and treat stroke.
