Interventional cardiologists often times will perform angioplasty to open narrowed arteries. They use a long, thin tube called a catheter that includes a balloon on its tip. During the procedure, they will inflate the balloon at the blockage site in the artery to flatten or compress the plaque against the artery wall.
Balloon angioplasty can also be used to open narrowed vessels in many other parts of your body. A stroke most often takes place when the carotid arteries become blocked and the brain does not get enough oxygen. Angioplasty can also be performed in the aorta, the iliac artery, the femoral artery, the popliteal artery, and the tibial and peroneal arteries.
