Peripheral Atherectomy

Also known as: Debulking atherectomy

Duration: About 2 hours

An atherectomy is a term for a group of procedures that use sharp blades to remove plaque (fat and calcium buildup) from the clogged arteries.

A peripheral atherectomy removes plaque from the peripheral arteries. It is a minimally invasive procedure that follows a peripheral angiogram to improves the blood flow to your limbs when severe calcium and/or fat builds up in your arteries and will not allow the insertion and expansion of a stent.

How the procedure is performed: 

  • Firstly, a peripheral angiogram is performed to check for any blocks in the peripheral arteries. A catheter (a thin, long tube) is placed in either your legs or groin and is monitored by an x-ray camera until it reaches the targeted artery.
  • A contrast dye is then infused so that the arteries can be seen. 
  • If an artery is blocked, your cardiologist will determine if a peripheral atherectomy is needed to remove plaque (fat and calcium buildup) from the clogged arteries.
    • Rotational Atherectomy involves removing plaque by using a rotating catheter with a diamond-tipped blade
    • Orbital Atherectomy – involves using the Diamondback 360° Orbital Atherectomy System to remove the plaque with orbital motion
    • Laser Atherectomy – uses a laser-tipped catheter to treat complex blockages
  • Once the atherectomy is completed, your cardiologist will determine if a balloon angioplasty with or without stent placement is required.
