Testing and diagnosis of cerebral vascular accident roof

To determine the best treatment for stroke, the researchers emergencies to find out what type of stroke are and what parts of the brain are affected. The other possible causes of symptoms, such as a brain tumor or drug reactions, should also be excluded. Your doctor may use a number of tests to determine the risk of stroke.

 

Physicals. The doctor will request or a family member has symptoms of, at the beginning, and what you start, and then assess whether the symptoms are still present.

The doctor wanted to know what kind of drugs, and have experienced any head injury. Your doctor will also ask about personal history and family of heart disease, stroke or TIA. Your doctor will check your blood pressure and use a stethoscope to listen to heart and listen carotid (neck), may indicate atherosclerosis. Your doctor may use an ophthalmoscope to check for signs of small crystals of cholesterol or blood clots in the blood vessels in the back of the eye.

The various blood tests provide care team important information such as blood clots and supervise g of sugar in the blood is abnormally high or low blood chemistry data have important balance, or may be contaminated identical. Clotting time and the level of sugar and chemicals key must be managed as part of stroke care. The infection must be treated well.

Computer tomography (CT). Brain imaging plays an important role in determining if there is a type of stroke. Computerized tomography angiography (CTA) is a specialized CT, in which dye is injected into the vein and the X-rays to create a 3-D images of blood vessels in the neck and brain. The doctors find aneurysm or arteriovenous malformation and evaluation of arterial narrowing. CT scan was performed without dyes, can provide images of the brain and bleeding, but provide little information about the blood vessels.

Magnetic resonance imaging (MRI). In the images, the strong magnetic field and radio waves to create 3-D brain. MRI can detect brain cells damaged by a stroke ischemia. Magnetic resonance angiography (MRA) using a magnetic field, radio waves and dye is injected into a vein to assess the arteries in the neck and brain.

Carotid ultrasound. This procedure may show narrowing or clotting in the carotid artery. A wand-like device (transducer) painlessly sends high-frequency sound waves into the neck. The sound waves travel through the tissue and then back, creating the image on the screen.

Angiography. This procedure for a look artery in the brain normally not visible in X-rays. The doctor put a thin, flexible tube (catheter) through a small incision, usually in the groin area. The catheter is manipulated through the artery and into the carotid or vertebral column. Then doctors inject a dye through the catheter to provide X-ray images artery.

Echocardiography. Ultrasonic technology to create images of the heart, allowing doctors to see if a clot (embolus) from heart went into the brain and cause a stroke. Your doctor may need to use Transesophageal echocardiography (TEE) to see a clear heart. In this procedure, to swallow an e au flexible probe with a transducer is built. Since then, the exploration of the esophagus - the tube connecting the back of the mouth e ến stomach. Because the esophagus directly behind the heart, very clear, detailed ultrasound images can be created, allowing a better view of the clot can not be seen clearly in the echocardiographic examination traditional.
