What is Mechanical Thrombectomy ?  It's a stroke treatment technology that helps reduce disability.

          Mechanical Thrombectomy this is a treatment method for ischemic stroke where a doctor uses a small catheter to directly remove the blood clot from a blood vessel in the brain. This helps restore blood flow more quickly, reduces brain damage, and increases the patient's chances of recovery.

          It is currently considered one of the key technologies in treating stroke emergencies, especially in patients with major cerebral artery occlusion.

 

What causes a stroke?

          Stroke caused by a blood clot blocking a blood vessel in the brain prevents sufficient blood and oxygen from reaching the brain.

When the brain is deprived of blood:

  • Brain cells begin to be damaged.
  • Speech, movement, and cognition become impaired.
  • This can lead to paralysis, stroke, or death.

 

 

How does mechanical thrombectomy help treat stroke ?

         The doctor will use a catheter through a blood vessel in the groin or wrist, and then insert a specialized instrument to the site of the blockage to directly remove the blood clot from the cerebral artery.

 

Advantages of Mechanical Thrombectomy

  • Opens blood vessels quickly
  • Reduce brain damage
  • Reduce the long-term risk of stroke.
  • Increase the chances of returning to a life as close to normal as possible.

 

Who might be suitable for this treatment?

  • Stroke patient due to a major cerebral artery occlusion.
  • People who experience sudden symptoms such as facial asymmetry, slurred speech, or arm weakness.
  • Those who arrive at the hospital within a timely manner.
  • Those who have been evaluated by a specialist physician.

This depends on the doctor's discretion and the results of the diagnostic tests.

 

What are the risks of delaying stroke treatment?

Stroke is a condition that doctors call "Time is Brain"  the later you come, the worse it gets.

  • The brain is damaged even more.
  • The risk of paralysis increases.
  • The chance of recovery decreases.
  • They may lose the ability to perform daily living activities.

Therefore, if you suspect a stroke, you should go to the hospital immediately.
