PAD: Atherectomy
A catheter-based treatment that removes plaque from narrowed arteries in selected cases of peripheral artery disease.
Overview
A vascular team may consider it to improve blood flow and relieve symptoms of peripheral artery disease, depending on the location and type of narrowing.
Atherectomy removes or modifies plaque that restricts blood flow in an artery. It may be combined with angioplasty or stenting as part of a vascular treatment plan.
What to expect
Imaging, such as angiography or vascular ultrasound, helps assess the blockage. Follow food, drink and medicine instructions, especially those concerning anticoagulants.
Through a blood-vessel access site, a catheter is advanced to the narrowed area. A specialised cutting, rotating or laser device treats the plaque. Local anesthesia and sedation may be used.
The team monitors circulation and the access site. Rest and activity restrictions depend on the approach; discharge may be the same day or after observation.
Risks
Risks include damage or perforation of the artery and plaque fragments blocking smaller downstream vessels. Report a cold or numb leg, worsening leg or groin pain, redness or swelling promptly.
