(Leg Artery Bypass Surgery; Femoral Popliteal Bypass;)


Femoropopliteal bypass is surgery to route blood around a blocked main leg artery. A graft is made from a vein or artificial tube. The graft makes a new path for the blood.

Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:

  • Excess bleeding
  • Problems from the anesthesia
  • Blood clots
  • Damage to other organs or structures
  • Infection
  • Heart attack

What to Expect

Prior to Procedure

The doctor may meet with you to talk about:

  • Anesthesia options
  • Any allergies you may have
  • Current medicines, herbs, and supplements that you take and whether you need to stop taking them before surgery
  • Fasting before surgery, such as avoiding food or drink after midnight the night before
  • Whether you need a ride to and from surgery
  • Tests that will need to be done before surgery


The doctor will give:

Description of the Procedure

An incision will be made in the leg. The doctor will take out a vein. The vein will be used to make the bypass graft. If the vein cannot be used, an artificial vein is used.

Next, an incision will be made in the groin. It will 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. The other end will be stitched into the popliteal artery. The doctor will check the graft for leaks and repair any. The clamps will then be removed. This will allow blood to flow through the graft to the lower leg. The incisions will be stitched. A bandage will be placed over the site.

Sometimes a vein in the thigh is used as a graft while left in place. In this procedure, the valves inside the vein will be removed with a small scope and tool. The vein will then be attached to the arteries to form a graft.

How Long Will It Take?

1 to 3 hours

Will It Hurt?

There may be some pain for weeks or even months. Pain medicine will help.

Average Hospital Stay

7 to 10 days
