Can you tell me how atherectomy deal with severe peripheral arterial disease?

Might help symptoms: Atherectomy refers to the physical removal of plaque material from a blood vessel. If you have an obstruction in one of your arteries your doctor might use this method to open the artery to bring more blood flow to the affected area and reduce symptoms associated with obstruction such as pain upon walking and pain at rest.

Removing plaque: Atherectomy is the removal of plaque build up in the lining of an artery. The plaque causes a narrowing of the arterial lumen decreasing blood flow. By removing the plaque, there is increased flow in that artery. It can be done by a variety of techniques: using a laser, or devices that act like a plane to shave the plaque and others that are like a drill or file.
