A fem-pop bypass uses a natural or synthetic graft to create the detour around the blockage beginning at your groin/thigh crease and ending at the inner knee, or sometimes the calf or foot.
An incision, about 4–8 inches long, is made at the groin crease and again at the end point. If your own vein is used to create the graft, other small incisions may be made on the inner portion of the thigh. Otherwise, a synthetic tube made of fabric or plastic will be used. The graft is sewn to the artery at both ends with fine stitches.
Surgery can take 1.5 to 6 hours.
