what vein can be grafted and used for coronary bypass surgery. What other vessels may also be used?
- hamid bLv 410 years agoBest Answer
Normally the Saphenous Veins (veins in the legs) are used. They are harvested, cleaned, have the valves removed and only a small portion (5 to 10 centimeters) are used for each graft.
The second most common vessel used is the Left Internal Mammary Artery, LIMA. LIMA runs right behind the left breast muscle. The other artery used is the RIMA, the Right Internal Mammary Artery.
If they cannot use the Saphenous Veins, they usually go to the arms and use some of the veins in the arms.

During this surgery, the doctor takes a vein or artery from another part of your body and uses it to create a detour (or graft) around the blocked area in your artery.
* Your doctor may use a vein, called the saphenous vein, in your leg. To reach this vein, an incision will be made along the inside of your leg, between your ankle and the groin. One end of the graft will be sewn to your coronary artery. The other end will be sewn to an opening that will be made in your aorta.
* The internal mammary artery (IMA), in your chest, can also be used as the graft. One end of the IMA is already connected to your aorta, so just one end will need to be attached. It will be sewn to your coronary artery.
* Other arteries are also now being used for grafts in bypass surgery. The most common one is the radial artery, in your wrist.
Ten years after CABG surgery, only 66% of vein grafts are open compared to 90% of internal mammary arteries.Source(s): http://en.wikipedia.org/wiki/CABG http://www.nlm.nih.gov/medlineplus/ency/article/00... http://www.medicinenet.com/coronary_artery_bypass_... http://www.merck.com/mmhe/sec03/ch033/ch033a.html#...

The choice of conduits is highly dependent upon the particular surgeon and institution. Typically, the left internal thoracic artery (LITA) (previously referred to as left internal mammary artery or LIMA) is grafted to the left anterior descending artery and a combination of other arteries and veins is used for other coronary arteries. The right internal thoracic artery (RITA), the great saphenous vein from the leg and the radial artery from the forearm are frequently used. The right gastroepiploic artery from the stomach is infrequently used given the difficult mobilization from the abdomenSource(s): doc

They normally take veins out of your legs. They may open up the whole length of the leg to extract what they need.
