Veins are sometimes used to replace arteries that are diseased. Removing them is called harvesting.
Leg veins are often 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.
Vein grafts are most often used to channel blood flow around blocked arteries.

Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
Things that may raise the risk of problems are:
The surgical team may meet with you to talk about:
The doctor will give general anesthesia. You will be asleep.
The surgery will be done one of two ways:
A long incision will be made in the skin. It will expose the whole length of vein. Every branch of the vein will be tied off. The vein will be removed. The skin will be closed with stitches or staples. A bandage will be placed over the site.
Two small incisions will be made at either end of the vein. A long, thin tool (endoscope) will be passed through one of the incisions. It has a camera that helps the doctor see the area. The tool will separate the vein from its branches and surrounding tissue. The vein will then be removed through the second incision. The incisions will be closed with stitches. A bandage will be placed over the site.
Vein harvesting is usually done at the same time as the main procedure. It does not add extra time.
There may be some pain and discomfort after the procedure. Medicine and home care help.
The hospital stay depends on the main procedure. Vein excision will not add time to the stay.
During your stay, the hospital staff will take steps to lower your risk of infection, such as:
There are also steps you can take to lower your risk of infection such as:
