Stroke occurs when the blood does not reach the brain. As a result, oxygen and nutrients to brain cells die and are not.
One of the main causes of disability and death, stroke! Among the types of strokes are ischemic strokes are the most important ones. Because more than 80 percent of all strokes in the world of this type!
Having realized the importance of this type of stroke. Let's symptoms, causes, prevention and treatment of stroke, obstructive examine together.
Ischemic stroke or blockage (In English: Ischemic Stroke) One of the three most common type of stroke. Also known as cerebral ischemia or infarction, obstructive.
This type of stroke caused by a blockage in the arteries that send blood to the brain. The blockage of blood flow and oxygen to the brain and reduces the damage or death of brain cells.. If blood flow is not restored again quickly, it can cause permanent brain damage.
- Almost 87 percent of all strokes, ischemic stroke!
What are the symptoms of ischemic stroke?
Specific symptoms of ischemic stroke depends on the area of the brain that is damaged. General symptoms The most common are ischemic strokes:
- Vision problems, such as blindness in one eye or double vision
- Weakness or numbness in the extremities, depending on which arteries are affected by one or both parties may be involved
- Lethargy and confusion
- Loss of coordination
- Fall down one side of the face
- Aphasia, or speech problems after stroke
Once symptoms begin, it is necessary to treat as soon as possible. Otherwise makes permanent brain damage.
If you believe someone has had a stroke, using the following guide a person through Rate:

Although the Mild Stroke For a short time it takes and usually resolve spontaneously, but needs to see a doctor. The stroke can be a sign of warning for Full ischemic stroke Is.
How ischemic stroke diagnosed?
Your doctor can usually diagnose a physical examination, family history of ischemic stroke associated with use. Based on the patient's symptoms, your doctor can also give information on where the blockage is, get.
If symptoms such as Confusion And Unclear speech Have, your doctor may Blood glucose test Do. This test is for this reason that indicate signs of confusion and unclear speech The sharp decline in blood sugar Is.
A CT brain scans can also detect other diseases, such as ischemic stroke, hemorrhagic stroke (Bloodshed) Or help with brain tumor.
Once your doctor has diagnosed an ischemic stroke, will try to detect the beginning and the main reason. MRI is the best way to determine when an ischemic stroke is started.
experiments Used to determine the main cause of stroke include the following:
- Her ECG or electrocardiogram (ECG or EKG) To test abnormal heart rhythms
- Akvqlb (Eco cardiography) To clots and heart abnormalities
- Angiogram to see whether arteries are blocked and how severe obstruction
- Blood test for cholesterol problems and ...
What is the treatment of ischemic stroke?
The first goal of treatment is to restore breathing, heart rate and blood pressure to normal. If necessary, the doctor tries to reduce blood pressure in the brain with drugs.
The main treatment for ischemic stroke, intravenous administration of tissue plasminogen activator (tPA) , Which solves clots. When in the past four and a half hours of stroke onset to tPA is highly effective. The drug can be given after five hours of onset of stroke.
Because tPA can lead to bleeding, a history of the following if you can not use it:
- Hemorrhagic stroke
- Bleeding in the brain
- Recent surgery or head injury
As well as those taking anticoagulant drugs can not easily use the drug.
If you work tPA, the clot can be removed through surgery. Dissolve the blood clot surgery can be performed until 24 hours after the onset of stroke symptoms.
Long-term treatment includes Aspirin (Arid) Or an anticoagulant to prevent blood clots more.
اگر سکته ایسکمیک ناشی از یک بیماری مانند فشار خون بالا یا آترواسکلروز باشد، برای درمان سکته نیاز به درمان این موارد دارید. به عنوان مثال، پزشک ممکن است یک استنت را برای باز کردن یک شریان کوچک که توسط پلاک چربی بسته شده است در رگ قرار دهد.
پس از سکته مغزی ایسکمی، شما باید برای مدت حداقل چند روز در بیمارستان بمانید. اگر سکته مغزی موجب فلج شدن یا ضعف شدید شود، ممکن است نیاز به توانبخشی برای بازگرداندن توانایی های از دست رفته داشته باشید.
توانبخشی شامل کادر گفتاردرمانی، فیزیوتراپی، کاردرمانی و ارتز پروتز می باشد.
