PATHOLOGY

Detailed explanation-1: -This is called off-pump coronary artery bypass, or OPCAB. During bypass surgery: The doctor will take a vein or artery from another part of your body and use it to make a detour (or graft) around the blocked area in your artery.

Detailed explanation-2: -The saphenous vein is the most commonly used conduit for coronary artery bypass grafting.

Detailed explanation-3: -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).

Detailed explanation-4: -Endoscopic vein removal requires only a small incision at the knee to insert a lighted, flexible instrument called an endoscope before the saphenous vein is removed. In open vein removal, surgeons make either a long incision or many small ones to remove the vein.
