How long does a vein graft last?

However, its durability and longevity are not ideal. One year after coronary surgery, 10% to 20% of saphenous vein grafts fail. From 1 to 5 years, an additional 5% to 10% fail, and from 6 to 10 years, an additional 20% to 25% fail.

What is venous graft?

A vascular graft (also called vascular bypass) is a surgical procedure that redirects blood flow from one area of the body to another by reconnecting the blood vessels.

Where do grafted veins come from?

Coronary artery bypass surgery restores normal blood flow to the heart by creating a “detour” (bypass) around the blocked artery/arteries. This is done by using a healthy blood vessel, called a graft. Grafts usually come from your own arteries and veins located in the chest, leg or arm.

What is a saphenous vein graft used for?

Saphenous vein grafts (SVGs) are the most frequently used conduits for coronary artery bypass graft (CABG) surgery but are associated with 10-year vein graft failure (VGF) rates of 40−50%.

How do vein grafts work?

Your doctor attaches one end of the graft above the blockage and the other end below the blockage. Blood bypasses the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery.

What causes vein graft failure?

Three processes are responsible for vein graft failure. Thrombosis, intimal hyperplasia and accelerated atherosclerosis contribute to graft failure in the acute, subacute and late postoperative periods, respectively.

Which veins are used for CABG?

Coronary artery bypass graft surgery usually lasts 3 to 6 hours. But it may take longer depending on how many blood vessels are being attached. Blood vessels can be taken from your leg (saphenous vein), inside your chest (internal mammary artery), or your arm (radial artery).

Why saphenous vein is used in CABG?

The saphenous vein (SPV) is a commonly used conduit for bypass due to the ease of harvest, which can generally be done through minimally invasive procedures, with less scarring and faster recovery.
