Radial artery or saphenous vein harvesting involves removing a blood vessel to use in coronary artery bypass grafting (CABG). This heart surgery treats coronary artery disease. Your provider attaches the harvested blood vessel to your aorta and a blocked artery. Blood flows through the grafted blood vessel, bypassing the blocked coronary artery.
Radial artery or saphenous vein harvesting is often part of coronary artery bypass surgery. It’s a procedure that takes a blood vessel from one part of your body to use as the bypass.
Your healthcare provider surgically removes either a healthy radial artery from an arm or a saphenous vein from a leg. They then attach one end of this harvested blood vessel (called a graft) to your aorta, your body’s largest artery. The other end of the graft attaches below the section of a blocked coronary artery. This harvested graft allows blood to flow freely to your heart, bypassing your blocked artery.
Your radial artery branches from your brachial artery, a major blood vessel in your upper arm. You have a main radial artery that runs on the inside of each forearm from your elbow to your wrist. The artery lies just beneath the surface of your epidermis, the outermost layer of your skin.
The saphenous vein starts in your foot and runs up your calf (lower leg). It connects to the femoral vein in your thigh. The saphenous and femoral veins in your legs have special pumping mechanisms and valves. They send blood that no longer has oxygen back to your heart to get oxygen. The saphenous vein is also known as the greater saphenous vein and long saphenous vein.
Your healthcare provider will order tests to assess the extent of the coronary artery blockage. The results will help determine which artery or vein to harvest for the bypass surgery. These tests may include:
Your healthcare provider will harvest either a radial artery or saphenous vein from your nondominant side. To decide which one to use, they consider your test results, as well as these factors:
You should follow your healthcare provider’s instructions before the procedure. You may need to:
Harvesting of a blood vessel graft may take place using:
You may need a heart-lung bypass machine during surgery. This machine does the job of your heart and lungs during the procedure.
During coronary artery bypass surgery, your provider:
The following things occur after blood vessel harvesting and CABG:
Blood vessel harvesting makes coronary artery bypass grafting possible. Most artery or vein harvesting procedures take place endoscopically. This minimally invasive surgery requires smaller incisions than an open surgical procedure.
Benefits of endoscopic artery or vein harvesting include:
Risks of artery or vein harvesting include:
Your main focus will be on recovering from bypass surgery. After discharge from the hospital, you should follow your healthcare provider’s instructions. This aids your recovery and lowers your risk of postoperative complications.
Your at-home recovery may include:
Coronary artery bypass surgery using a harvested blood vessel is a life-saving procedure for most people. But, 1 in 10 people who have bypass surgery using a harvested saphenous vein experience a graft failure within 12 months of the procedure. Plaque can form in the grafted vein, causing atherosclerosis that can compromise the graft blood flow in up to 50% of the vein grafts at 10 years after surgery. Blood clots and thrombosis may also occur. These complications are less likely when bypass surgery takes place using a grafted radial or internal mammary artery.
You should call 911 if you think you’re having a heart attack. Call your healthcare provider if you experience:
A note from Cleveland Clinic
You may need radial artery or saphenous vein harvesting in addition to your internal mammary artery for use in coronary artery bypass grafting (CABG). This heart surgery treats coronary artery disease by using a harvested blood vessel to deliver blood to your heart. Your surgeon might use an internal mammary artery, radial artery or saphenous vein to bypass blocked coronary arteries. Blood vessel harvesting typically takes place using a minimally invasive endoscopic procedure. But some people need open surgery. Your healthcare provider will discuss which blood vessel to use and the best harvesting procedure for your unique situation.
