Atherectomy and angioplasty are methods that can be used to open arteries without surgery.
There are several different devices that can be threaded through blood vessels to the site of a narrowing or blockage. These devices remove the obstruction so that blood flow is restored.

Most often, these procedures are done when an artery is narrowed by atherosclerosis . If the artery is too narrow, blood is no longer able to pass through. The body part then suffers from lack of oxygen, also called ischemia. This can cause different symptoms, depending on the part of the body that is not getting enough oxygen.
If you are planning to have an atherectomy or angioplasty, your doctor will review a list of possible complications, which may include:
Factors that may increase the risk of complications include:
Be sure to tell your doctor if you are allergic to shellfish, iodine, or contrast dye.
You will be thoroughly evaluated before deciding on the best procedure. This may involve contrast x-rays, ultrasound, or computerized scans to identify the area of concern. You will be asked not to eat or drink anything for several hours before the procedure.
Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to one week before the procedure, like:
You will most likely be sedated, but not put to sleep. A local anesthetic will numb the site of insertion of the device.
You will be lying down. The room will have x-ray machines and a variety of surgical equipment. Depending on the artery to be opened, a blood vessel in your groin or arm will be prepared and covered with sterile drapes. Your doctor will puncture your numbed skin. A tube called a catheter will be placed into your blood vessel and passed to the site of the obstruction. Contrast material may be injected through the catheter to visualize the obstruction on the x-rays. There may be more than one location that requires opening. The device used will depend on the type of obstruction and location in the vessel. Possible approaches include:
Recovery time is minimal. You will be moved to another room to recover.
Between 30 minutes and two hours
Some minor discomfort may accompany the procedure.
This procedure is done in a hospital setting. You may need to stay overnight. You may be kept longer if complications arise.
After the procedure, be sure to follow your doctor's instructions .
Depending on the site of your procedure, call your doctor if you experience the following:
