Femoropopliteal Bypass Surgery
(Leg Artery Bypass Surgery)
by Editorial Staff and Contributors
During femoropopliteal bypass graft surgery, a vein or an artificial tube is used to create a bypass around a blocked main leg artery. The blocked arteries in the legs are usually caused by a buildup of plaque. When this buildup occurs, it is called peripheral arterial disease (PAD).
Reasons for Procedure

Description of the Procedure
The doctor will make a cut in the skin on the leg. Through this cut, the doctor will take out a vein that will be used to make the bypass. If the vein cannot be used, then an artificial vein is used.
Next, an incision will be made in the groin to expose the femoral artery. This is the artery in the thigh. The doctor will make another incision at the back of the knee to expose another artery. This is called the popliteal artery.
The doctor will use clamps to block the flow of blood through these two arteries. One end of the new bypass vein will be stitched into the femoral artery, and the other end will be stitched into the popliteal artery. Once attached, blood will be passed through the graft to check for leaks. If leaks are found, the doctor will repair them. The clamps will then be removed. This will allow blood to flow through the graft to the lower leg. The doctor will use stitches to close the incisions.
In some cases, a vein in the thigh will be used as a graft while left in place. This is called in situ. In this procedure, the valves inside the vein will be removed with a small scope and a small cutting tool. The vein will then be attached to the arteries to form a graft.
