Peripheral Artery Bypass Surgery
Surgery to bypass a blocked leg artery can relieve your symptoms. The bypass is done with a graft, a special tube that reroutes blood around a blockage.
Types of Grafts
-
Blood vessel grafts often come from your own leg. They are removed and prepared at the time of the bypass. In some cases, a leg vein is left in place and connected to the artery (an in situ procedure).
-
Manmade (synthetic) grafts are materials easily accepted by the body. These grafts work best on arteries at or above the knee.

Attaching the Graft
Peripheral bypass grafts carry blood from the femoral artery in your thigh to an artery further down your leg. During the surgery, a graft is stitched into the artery above and below the blockage. This creates a new passage for blood flow. The blocked section of the artery is usually not removed. After the graft is in place, the incisions in the skin are closed with stitches or staples.

The type of bypass depends on where your artery

| Distal bypass: Used for the lower part of the leg. Graft may be your vein or both your vein and synthetic material. |
is blocked.
