Why perform it?
If you have suffered stroke caused by a blockage in a large artery but you are not suitable for or have not responded to thrombolysis, this procedure is a possible treatment for you.
What are the risks?
The insertion of catheters and guidewires in arteries to the brain carries a low but definite risk of bleeding or the movement of blood clots to previously unaffected parts of the brain. Endovascular treatment is inadvisable if your admission to hospital after the stroke was delayed, as this carries a higher risk of complications.
