Directional Atherectomy
A directional atherectomy removes fatty buildup (plaque) from the arteries. By cutting through the blockage, blood can flow more freely. You may need this procedure to treat critical limb ischemia or CLI (severe blockage in the arteries of your legs).
How to Prepare for a Directional Atherectomy
To prepare for a directional atherectomy, you should:
- Arrange blood tests and imaging tests before the procedure
- Ask your doctor about stopping medications if necessary
- Avoid eating and drinking eight hours before your procedure
- Schedule someone to drive you home after the procedure
What to Expect During a Directional Atherectomy
A directional atherectomy usually takes one to two hours. You may be able to have it as an outpatient procedure (same-day surgery).
First, you will receive an intravenous (IV) line in the arm for fluids and medicines. Next, you will receive a sedative or local anesthesia (medicine to help you relax and not feel pain) through the IV. You will be awake during the procedure.
Once the medicine is working, we make a small cut to reach the blockage. A doctor will insert a long, thin tube (catheter) with a tiny rotating cutting blade into your artery. The blade will remove the plaque buildup, allowing blood to flow. After this, the doctor removes the catheter. We use stitches and a bandage to cover the cut, and then move you to a recovery room.
What Happens After a Directional Atherectomy
After your surgery, our team will monitor your heart rate and blood pressure. Depending on your results, you may be able to go home the same day. Once your doctor releases you, you can have someone drive you home. Follow your doctor's instructions for returning to normal activities.
