Popliteal artery for a heart bypass My father undergone surgery 10 years ago to get 3 bypasses close to the heart. Surgeons did a very long cut on his leg to get the material to make the bypasses they would later put on his chest. What I understood at that time, is that they took three sections of the popliteal artery to obtain the material to make those bypasses, and that they fixed the cuts again to restore such artery. The reason why that artery was chosen is because it is very elastic and surgeons can extract a section and stick it together again. My father is convinced they removed the whole popliteal artery from that leg and chopped it down to make the material they would use for the bypasses. I am trying to find information about this procedure to find out who is wrong. The problem is that we both are completely illiterate in medical stuff, so we are lost in the mist. What I found is that the popliteal artery is important and blockage could be problematic.

I'm not a physician, but I suspect the popliteal artery may not have been the vessel used. The popliteal artery has a very important role in supplying the leg with blood, and maintaining the blood supply from it to the lower (distal) leg is sometimes reason for harvesting other vessels.

You described a very long cut, which sounds like what you would see for harvesting the great saphenous vein. The great saphenous vein is the longest vein in the body, and dominates recent scientific publications in response to a query of ''coronary bypass harvesting''. (There are publications in that batch evaluating newer endoscopic techniques in which the long cut can be avoided) Wikipedia reviews the use of this vein reasonably well.
