Veins can sometimes be used to replace arteries that are diseased. The process of removing them is called harvesting.
Leg veins are frequently used for vein harvesting. For open chest procedures, like coronary artery bypass grafting (CABG), veins or other blood vessels in the chest are often used.
Diseased arteries with atherosclerosis have a buildup of plaque that can block the flow of blood. Coronary (heart) or carotid arteries to the brain are often repaired by making a bypass. Vein grafts are most often used to bypass these blocked arteries.

Complications are rare, but no procedure is completely free of risk. There may include:
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:
The preparation you will need will be determined by the primary procedure. In most cases, it will be a major cardiac or vascular surgery for which you will be hospitalized and evaluated thoroughly.
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 not be able to eat or drink for 8 hours prior to the procedure.
You will be given general anesthesia. It will make you sleep.
A long cut in the skin will be made to expose the entire length of the vein. Every branch of the vein will be found and tied off. The vein will be removed. The skin will be closed with stitches or staples.
Two small incisions are made at either end of the vein. A special long, thin tool with a camera on the end (endoscope) is passed through one of the incisions and along the vein. The tool will separate the vein from its branches and surrounding tissue. The vein will then be removed through the second incision at the other end of the vein.
The primary surgery will take place. Your leg (or legs) will be wrapped tightly to prevent bleeding from the remaining veins.
Vein harvesting is usually done at the same time as the primary procedure. It does not add time to the total surgery.
Leg pain from the long incision method may be significant. Talk to your doctor about a plan to manage pain.
Your hospital stay will depend on your primary procedure. Vein excision will not extend your stay.
During your stay, the hospital staff will take steps to reduce your chance of infection such as:
There are also steps you can take to reduce your chances of infection such as:
