Stroke Treatment
What is a Stroke?
Stroke is one of the nation’s leading causes of death and the major cause of serious, long-term disability.
Stroke is damage to the brain, spinal cord, or retina due to a disturbance in blood flow. More than 700,000 strokes occur per year in the United States and make up more than half of all hospital admissions for neurologic disease. Stroke is the leading cause of serious long-term disability and is consistently one of the leading causes of death in our country. Many of those who suffer stroke are unable to return to work leading to enormous indirect costs and lost wages.
Identifying stroke symptoms and acting quickly to be evaluated by emergency medical personnel is the first step in the treatment of any type of stroke. Calling 911 is a must and has been shown to reduce the time it takes for the stroke patient to receive lifesaving treatment.
Hospital emergency staff will need to determine if a stroke is occurring and if so which major type of stroke is present.
Carondelet Health Network offers:
- A dedicated neurological critical-care unit
- Angio suite for conducting minimally invasive vascular and endovascular procedures
- Long-term outpatient care, including rehabilitation
- Short Term Inpatient rehabilitation unit tailored to Stroke and Spine patients (Carondelet St. Mary's Hospital)
- Neurological Critical Care
- The critical-care unit is staffed by a neurointensivist – a physician who takes a team approach in working closely with surgeons, radiologists, ER staff, pharmacists, rehabilitation therapists and other care providers in neurologic emergencies. Multiple studies have shown that the outcome for patients with critical neurological conditions – such as acute ischemic stroke, aneurysm and hemorrhage – is significantly better when they are cared for by a neurointensivist.
- Interventional Neurology
- Neurointervention allows doctors to use highly specialized techniques, where possible, to avoid conventional open surgery of the brain and spine. It has become essential for comprehensive stroke care.
What Causes a Stroke?
There are two major types of stroke. Non-bleeding strokes are the most common type of strokes. These are also called ischemic strokes. Bleeding or hemorrhagic strokes are less common and are often associated with the rupture of an artery.
Non-bleeding strokes are often due to arteries suddenly closing and subsequently being unable to carry oxygenated blood cells to that part of the brain, spinal cord, or retina. Arteries becoming narrow with plaque development over many years due to the effects of high blood pressure or diabetes can cause this. A common place that plaque can form is in the carotid arteries found in the neck. Narrow carotid arteries are associated with increased stroke risk. Ischemic strokes can also be caused by blood clots forming in organs such as the heart, which can then travel to the nervous system and obstruct blood flow causing damage.
Bleeding strokes are associated with arteries which rupture and cause damage. High blood pressure is one risk factor associated with bleeding strokes. Arteries can also enlarge and balloon in size forming aneurysms, which can rupture, and cause bleeding in the subarachnoid layer around the brain. Identifying brain aneurysms prior to their rupture can prevent subarachnoid hemorrhages.
Stroke Treatment
Non-bleeding strokes may be treated with a FDA approved clot- busting drug called t-PA. Quick investigation in the emergency center can determine if a patient with stroke symptoms is able to receive this drug. T-PA can be associated with severe bleeding complications and therefore can only be used within 3 hours of stroke symptom onset. In rare instances this drug may be used after this time window however best results are associated with its use as a clot buster as soon after stroke symptoms develop.
While not every stroke patient can receive t-PA, patients with stroke are admitted to the hospital and other treatments are implemented. Treatments can include control of vital signs, fluid and electrolyte management, and even surgical treatments to relieve pressure in the nervous system that can result from large strokes. Multiple tests are also performed to help identify the location and cause of the stroke so that the best preventative strategy can be implemented to reduce the risk of recurrent strokes.
In rare circumstances specialists at Western Neuro can recommend that a stroke patient be evaluated for retrieval of clot found in a major artery may be causing stroke. Such clots may not respond quickly enough for t-PA to work and may require the expertise of a vascular neurosurgeon to perform an invasive catheter procedure to help treat stroke.
Bleeding strokes often require close observation in the neurological intensive care unit to identify changes in neurological function that may lead to surgical intervention. Subarachnoid hemorrhages will need their aneurysms treated with either surgical or non-surgical treatment.
Frequently asked questions about stroke
Yes. Identifying and treating high blood pressure, elevated cholesterol, and diabetes can reduce the risk of both non- bleeding and bleeding strokes. Blood thinner medications can reduce the risk of stroke due to atrial fibrillation. Exercise and weight loss can also help prevent stroke. Imaging studies can identify plaque in the carotid arteries or aneurysms in the brain. There are also both surgical and non-surgical treatments for the treatment of carotid artery plaque formation and brain aneurysms.
In addition, following a stroke, medications can be given to reduce the risk of plaque formation on arteries. Often, there are multiple risk factors present, and a comprehensive prevention plan with a neurologist and/or neurosurgeon working together with one’s primary care physician can help reduce the risk of stroke.
A transient ischemic attack or TIA is a warning sign of stroke. Symptoms of TIA’s are the same as those for stroke and often only last minutes. While only a small proportion of strokes are preceded by a TIA, these symptoms are very important since strokes can occur within days after a TIA occurs.
A TIA requires an urgent evaluation to prevent stroke. A TIA Clinic is present at Western Neuro to more quickly evaluate a patient with TIA. A typical TIA evaluation will include a neurological exam, lab tests, and imaging of the brain, blood vessels, and heart.
Comprehensive Stroke Center Certification
Carondelet Health Network is home to the Carondelet Neurological Institute at St. Joseph’s Hospital. Our stroke program is designated as a Comprehensive Stroke Center Certification from DNV Healthcare. Comprehensive Stroke Centers represent the most advanced stroke treatment available in each geographic area. The certification affirms that Carondelet Neurological Institute addresses the full spectrum of cerebrovascular diseases – diagnosis, treatment, rehabilitation and education – and establishes clear metrics to evaluate outcomes. It is based on standards created by the Brain Attack Coalition and the American Stroke Association.
Comprehensive Stroke Centers can treat patients suffering hemorrhagic or large ischemic strokes with follow up care in an intensive care unit. Centers can also treat patients with suspected aneurysmal subarachnoid hemorrhage, those requiring specialized testing or therapies such as endovascular surgery, and those requiring multispecialty management. The Carondelet Neurological Institute at St. Joseph’s Hospital receives rapid transfers from smaller hospitals across the region in Southern Arizona.
Primary Stroke Center Certification
Carondelet Health Network is committed to providing quality stroke care with a Primary Stroke Center Certification from DNV Healthcare at St. Mary’s Hospital. This certification recognizes rigorous standards and a commitment to excellence for stroke care. Carondelet St. Mary’s Hospital provides the critical elements for long-term success in improving outcomes.
