You will have had investigation for your leg pain such as CT and MRI prior too needing a bypass procedure performed. If you have had an angioplasty or stenting done that has not been successful or been suitable to correct the problem, you may now be recommended to have a bypass graft done. Bypasses are used to re-route the blood supply around the blocked/affected area in a limb or other area in the circulatory system, much like a detour when a road is being repaired. An ultrasound scan will be done to determine if a vein from your leg is suitable to use for the bypass. If suitable the vein/s will be marked prior to surgery on your leg with a surgical marking pen. If no suitable vein is found then a synthetic graft will be used. The chosen graft will be tunnelled into position and attached/stitched to the artery on either end of the graft.
Your surgeon will discuss the risks of surgery with you at your clinic appointment prior to signing a consent form for the procedure.
