Angioplasty is a procedure that can open blocked arteries.
A doctor inserts a long, narrow catheter into an artery in your groin.
He or she guides the catheter to your blocked artery.
The doctor inflates the small balloon on the end of the catheter, reopening the artery. He or she may put a stent (small tube) into the artery to keep it from getting blocked again.
This procedure cannot be done on a totally blocked carotid artery.
