Common questions about stroke

What is a stroke?

The brain needs a constant supply of oxygen and nutrients in order to function. A stroke, which can also be referred to as a brain attack, occurs when blood flow to the brain is disrupted.

A stroke is caused when either:

  • A blood clot blocks one of the vital blood vessels in the brain (ischemic stroke)
  • A blood vessel in the brain bursts, spilling blood into surrounding tissues (hemorrhagic stroke)

Even if there is a brief interruption in blood supply it can still cause problems. Brain cells begin to die after just a few minutes without blood or oxygen. Due to both the physical and chemical changes that occur in the brain with stroke, damage can continue to occur for several days.

Damage caused by strokes

Impairment of brain function occurs with the loss of brain cells.

A stroke can impair:

  • Movement
  • Speech
  • Thinking
  • Memory
  • Bowel and bladder function
  • Eating
  • Emotional control
  • Other vital body functions

Recovering from a stroke

Recovery from stroke and the specific impaired ability depends on the size and location of the stroke.

A small stroke may result in problems such as weakness in an arm or leg.

Larger strokes may cause paralysis, loss of speech or even death.

What can I expect if I am having surgery?

You will be given specific instructions on the time to arrive at the hospital and where to check in. Once checked in you will be directed to a pre-operation area where you will change into a hospital gown, and you may get white stockings to wear to help prevent blood clots in your legs after surgery.

Our endovascular nurses will talk with you about the type of anesthesia and pain medication you will be receiving. And an IV line will be placed in your arm for fluids and medicine throughout your surgery.

As with all surgeries, you will be asked to sign a standard consent form prior to surgery and your surgeon will discuss the specifics of any risks associated with your individual situation. If you have any questions prior to surgery, please do not hesitate to ask your doctor or any other member of your healthcare team.
