Diagnosis and Treatments
To determine if you are having a stroke, we perform a physical examination, checking for signs like drooping facial muscles, inability to lift an arm, slurred or jumbled speech. We then use advanced procedures and technology to decide if you are having, or had, a stroke. Based on the results, we talk about treatment options and carefully monitor your condition.
Diagnostic procedures can include
These can tell physicians and emergency staff how fast a person’s blood clots, if blood sugar is abnormally high or low, if blood chemicals are out of balance or if an infection is present.
In this test, sound waves create images of the carotid arteries in the neck, showing blood flow and buildup of fatty plaques.
During this procedure, the physician inserts a thin, flexible catheter into a large artery — typically in the groin — and threads it past the heart to the arteries in the brain. He or she then injects a special dye into the catheter that travels to arteries throughout the brain. A series of X-ray images can then reveal details about the condition of the arteries.
Computerized Tomography (CT) Scan
This test uses X-rays and computers to create images of the brain. Sometimes, contrast dye is injected to make bleeding in the brain easier to see.
This test uses sound waves to create detailed images of the heart and can find a source of clots in the heart that may have led to a stroke.
Magnetic Resonance Imaging (MRI)
This test uses a powerful magnet and radio waves to produce images of the brain. It can detect bleeding in the brain and damage to brain tissue caused by an ischemic stroke.
Treatment for a Hemorrhagic Stroke may include
In the emergency room, a person suffering this type of stroke may be given drugs to counteract the effects of blood thinners, reduce pressure in the brain, reduce blood pressure, prevent seizures or prevent spasms of the blood vessels. When bleeding stops, a person will receive supportive medical care.
In some cases, the surgeon may need to remove blood and relieve pressure in the brain. Surgery can also repair blood vessel abnormalities associated with these types of strokes and may include clamping of the aneurysm, inserting a coil into an aneurysm, surgical removal of an aneurysm, and performing a surgical bypass of intracranial blood vessels to improve blood flow.
Treatment for an Ischemic Stroke may include
A surgeon may use a catheter to insert a tiny device to break up or remove a clot and/or deliver clot-busting drugs directly into the area where a stroke is occurring.
Therapy with clot-busting drugs administered within three hours of a stroke’s development can be very effective in ensuring survival and reducing complications. Some people may also be given aspirin to reduce the likelihood of another stroke or an injection of recombinant tissue plasminogen activator (TPA), which restores blood flow by dissolving a clot.
A surgeon may remove plaques from carotid arteries in the neck or insert a balloon to expand the artery and insert a stent to improve blood flow.
