Atherectomy

Atherectomy is a minimally invasive surgical method of removing atherosclerosis from a large blood vessel. It is generally used to treat peripheral arterial disease of the lower extremities.

The procedure involves making an incision in the groin area and inserting a catheter into the femoral artery and carefully guiding it to the blockage. The surgeon uses live x-ray pictures to see the artery and monitor the blood flow inside the artery. This kind of x-ray is called fluoroscopy.

The surgeon then passes a guide wire through the catheter. The guide wire carries an atherectomy device to the blockage. Unlike angioplasty, where the buildup is pushed to the sides by a balloon to improve blood flow, the plaque is totally removed. This occurs when the atherectomy device either shaves part of the plaque away or grinds it up with a spinning diamond-tipped bur. This procedure is known as rotational atherectomy or rotablator.

After as much plaque as possible is removed but blood flow is still not restored, a stent may be inserted via the catheter and left in place to help keep the artery open.
