Carotid stenting is a procedure that is one done without a neck incision. The procedure is performed through a groin puncture.
With the use of X-ray guidance and special endovascular wires and catheters guided through the vascular lumen, a stent (metallic mesh tube) is inserted via the femoral artery and advanced up into the carotid artery to the site of the blockage, where it is expanded.
Typically patients who undergo this procedure have a supervised hospital stay for one day after surgery.
As with any operation, carotid stenting has a risk of minor and major complications, the most serious one being the risk of stroke.
You will want to discuss these thoroughly with your vascular surgeon.
