Carotid stenting

In carotid stenting, a surgeon sends a long, hollow tube, known as a catheter, through the arteries to the narrowed carotid artery in the neck. The surgeon then puts a small wire mesh coil, known as a stent, into the vessel to keep the artery from narrowing again. Finally, the surgeon removes the tube and the filter that was used to catch debris that might have broken off during the procedure.
