Cerebral Embolism: Symptoms, Risk factor, Cause, Treatment

Cerebral Embolism
Introduction

The most common cause of ischemic stroke is embolism.
If any abnormality occurs in the vessels like any rupture or surgery or infection which can cause damage inside of vessels wall, then fats or any unusual material deposits at that area and causing deposition and due to what embolism occurred. It may cause in any vessels into the living body.

An embolic stroke occurs when a blood clot that forms elsewhere in the body is released and transmitted to the brain via the bloodstream. If a blood clot in an artery and blocks the flow of blood, causing a stroke. 

It is a type of ischemic stroke. An ischemic stroke can occur when the arteries to the brain become blocked. The brain is the subject of the nearby arteries to supply blood to the heart and lungs. This blood flow helps to ensure that oxygen and nutrients reach the brain. 

If one of these arteries becomes blocked, the brain is unable to produce the energy it needs in order to function properly. These brain cells begin to die out, and if the blockage is more than just a few minutes.


Causation of Cerebral embolism

Cardiac origin

Atrial fibrillation and another arrhythmia (with rheumatic, atherosclerotic, hypertensive, or congenital heart disease)
Myocardial infarction with mural thrombus
Acute and subacute bacterial endocarditis
Heart disease without arrhythmia or mural thrombus (mitral stenosis, etc.)
Complications of cardiac surgery
Valve prosthesis
Nonbacterial thrombotic endocardial vegetations
Paradoxical embolism with congenital heart disease
Trichinosis


Noncardiac origin

The plaque or fat deposition inside the arterial wall is called Atherosclerosis. Atherosclerosis  of aorta and carotid arteries
From sites of cerebral artery thrombosis (basilar, vertebral, middle cerebral)
Thrombus in pulmonary veins
Fat
Tumor
Air
Complications of the neck and thoracic surgery

Undetermined origin


A stroke is when a blood clot that forms elsewhere in the body comes out and goes straight to the brain through the bloodstream.


Controlled risk factors for ischemic stroke include: - Cerebral Embolism

  1. high blood pressure
  2. high cholesterol
  3. smoking
  4. obesity
  5. lack of physical activity, the use of the drug

People with a family history of stroke, or an earlier mini-stroke are also at a higher risk. The Mild stroke is also known as a transient ischemic attack (TIA). - Cerebral embolism


In other uncontrollable risk factors include: 

The age over 40 years
old and latest deliveries
auto-immune diseases, weaknesses
Diabetes Mellitus
Cardiovascular abnormalities in the structure of the heart


Symptoms / Signs

These are the very common symptoms

  1. The patient can not speak well or understand the version well
  2. Paralytic walking, can not walk normally as a common person
  3. Numbness in the limbs or on one side of the face
  4. Temporary disability in cerebral embolism
  5. Embolic stroke does not cause any different symptoms. Symptoms can vary greatly from person to person and from stroke to stroke.

Muscle symptoms
  1. Muscle symptoms may include:
  2. Restricted muscle coordination
  3. Flexion or extension rigidity
  4. Feelings of weakness on the other side, or both, of the body
  5. paralysis on one side of the body
  6. Symptoms of comprehension


Mental confusion
  1. A modified level of awareness, which means you can be very dangerous
  2. Visible agnosia, or inability to see a large part of your line of sight


Other symptoms
  1. May diminish the vision
  2. Negative speech
  3. Dizziness and drowsiness
  4. Exhausted
  5. Difficulty swallowing
  6. Nausea
  7. Disturbed sleep and sleepiness

Treatment
Management of stroke
BP is to be monitored
Control of cerebral edema


Investigations

CSF examination
CT scan 
MRI


Experience

In my experience, I see the most symptoms or signs below:

The patient has impaired speech one or two times in a day but not frequently with sleepness in starting time. Some patients and patient parties ignore this condition. I see, it is the first and foremost symptom of stroke.

Then, the impairment frequency is more in the 2nd stage. If the patient doing some works, come for rest even sleepiness for some time, and regain again to work and it happens for some days.

The last and most effective in CVA or cerebral embolism is paralytic change on the face or limbs. And now the patient is aware to consult a physician.
