Embolic Stroke - Oren Zarif - Embolic Stroke
There are two types of stroke: ischemic and embolic. Ischemic stroke results from blocked blood flow to the brain, and is often caused by high cholesterol or atherosclerosis. Embolic stroke is the opposite of ischemic stroke, and results when the clot travels to the brain. People with atrial fibrillation are at risk for embolic stroke. Patients may experience blurred vision, memory loss, or difficulty swallowing.

Embolic stroke is a life-threatening condition, and rapid treatment is essential to reduce brain damage. Blood flow must be restored as quickly as possible to reduce the chances of permanent brain damage. Treatment includes clot-busting medications and the placement of catheters. Once the brain has received enough oxygen and nutrients, the patient can recover. However, embolic stroke can be extremely difficult to reverse, and often requires emergency surgery.

Some common symptoms of embolic stroke include difficulty speaking or understanding speech, numbness, and weakness. They usually affect one side of the body, so it is crucial to seek medical attention as soon as possible. It is also important to ask the person to raise both arms and repeat a simple phrase. If they cannot, call 911 immediately. If you think your loved one has an embolic stroke, call 911 right away. Quick treatment will improve the chances of a full recovery.

Although a reliable embolic stroke diagnosis cannot be made based on symptoms alone, a thorough diagnostic assessment is necessary to rule out other possible causes. Some cases are simple and have minimal comorbidities, whereas others have complex clinical and diagnostic findings that require further investigation. If these are your patients, remember that your patient's underlying health condition may be contributing to the development of an embolic stroke. A complete diagnostic workup will rule out the underlying cause.

In a population-based study involving 2555 patients, researchers determined that one-third of patients with CS had no known cause of the stroke. Therefore, they proposed a new term called "Embolic Stroke of Undetermined Source." This new type of stroke was a different type of cardiogenic embolism, small artery occlusion lacunar, or large artery atherosclerosis. A recent study showed a direct correlation between AAA plaque size and the risk of embolism.

The causes of embolic stroke vary greatly. However, some patients may have several risk factors, such as a PFO. Depending on the cause of an embolic stroke, a patient may be classified as cardioembolic or cryptogenic. Regardless of the underlying cause, the treatment for an embolic stroke should be determined early, and patients should be monitored carefully for signs and symptoms of stroke. They should also be evaluated for cardiovascular and neurological conditions, which might be a contributing factor.

The causes of embolic stroke are complex and can impact poststroke outcomes. In a study of 2261 patients with cryptogenic stroke and 2163 with embolic stroke of unknown cause, researchers determined that ESUS had a significantly lower functional outcome than cardioembolic stroke. Despite the lack of clear data, these results suggest that potential embolic sources are important predictors of clinical outcomes after a cryptogenic stroke.

An embolic stroke can be treated using emergency procedures, including carotid endarterectomy, which involves the removal of plaque lining the carotid artery. Another type of emergency treatment involves mechanical clot removal. The doctor inserts a catheter into the brain to break up the clot. If you're suffering from embolic stroke, Tampa General Hospital offers specialized care around the clock. Neurologists, neurosurgeons, and neuroradiologists work together to provide comprehensive stroke treatment as well as rehabilitation.

Despite these advances in medical care, research on this disease is still ongoing. New drugs and rehabilitation techniques are constantly emerging. Stroke rehabilitation specialists undergo regular refresher courses to keep up with these changes. By providing comprehensive care, doctors can reduce the negative effects of a stroke and improve the chances of a full recovery. It can be as simple as passive gymnastics massage, but the recovery time can take months or even years. There are numerous treatments available for stroke, from rehabilitation to medication.
