What is a Cerebral Embolism?
A cerebral embolism, the most common type of embolic stroke, occurs when a blood clot forms in one part of the body and then travels through the blood to the brain, where it blocks adequate oxygen and blood flow. As a result, brain cells may die off. Symptoms include trouble walking and speaking, as well as muscle paralysis and numbness. This is a medical emergency and requires immediate attention.
Causes of Cerebral Embolisms
A cerebral embolism may occur because of heart disease, heart surgery, or atrial fibrillation, a type of abnormal heart rhythm. Risk factors include obesity, smoking, sedentary lifestyle, drug use, high cholesterol, and high blood pressure. African Americans, people over 40 and women who have recently given birth are also at increased risk.
Symptoms of Cerebral Embolism
Stroke symptoms can include confusion, dizziness, nausea, headaches, difficulty speaking, vision problems, and sudden numbness of the face, arms or leg, especially on one side of the body. Muscles may be stiff. If a loved one is experiencing these symptoms, try to check the acronym F-A-S-T for signs that a stroke has occurred:
FACE: Does the patient’s face droop on one side when asked to attempt to smile?
ARMS: Does one arm sag when a patient is asked to raise both arms to the side?
SPEECH: Does the patient slur or lag when asked to say a simple phrase?
TIME: Call 911 immediately if these symptoms are apparent.
Diagnosis of a Cerebral Embolism
Your doctor will conduct a complete physical exam and order appropriate imaging tests, such as a CT scan, MRI, carotid ultrasound, or cerebral angiogram, to verify and treat a stroke.
Treatment of Cerebral Embolism
A tissue plasminogen activator can be administered through the arm to dissolve blood clots if the patient suffered an embolic stroke within just a few hours. Additionally, a carotid endarterectomy may be performed to remove plaque lining in the carotid artery to improve blood flow. A clot can also be removed manually with a catheter. Medications and lifestyle changes may be recommended to prevent another stroke.
