Atherectomy is a minimally-invasive procedure performed to remove fatty plaque from an artery that is partially blocked. Plaque slowly builds-up in the arteries over time and affects them by making them thicker and narrower. This is known as atherosclerosis.
Atherectomy usually has no complications, but as with any surgery, there is a risk of complications, such as embolization (the dislodgement of debris that blocks the arteries in the lower part of the leg) and perforation. These complications, however, are rare.
