Surgery
Bypass surgery in the leg arteries may be
used to treat severe or limb-threatening
peripheral arterial disease (PAD) that is causing
symptoms. Bypass surgery redirects blood through a grafted blood vessel to
bypass the blood vessel that is damaged. The grafted blood vessel may be a
healthy natural vein or artery, or it may be man-made.
You may
need surgery if you have symptoms of intermittent claudication and one of the following conditions:
- Your lifestyle or job is limited because of your
symptoms.
- Exercise has not relieved your
symptoms.
- Medicines have not relieved your symptoms.
The methods of bypass surgery vary depending on the size of
the affected artery and the location of the artery.
Surgery Choices
The types of surgery used to treat
PAD are categorized according to the location of the affected leg artery or
arteries. See a picture of

Should I have surgery (angioplasty or bypass surgery) for peripheral arterial disease?
What to Think About
Surgery for peripheral
arterial disease is used for people who have disabling
intermittent claudication; pain when at rest; open
sores (ulcers) that won't heal; or dying skin, muscle, bone, and nerve tissue
in their legs or feet (gangrene).
In rare cases,
some people need to have a leg, foot, or part of the foot amputated. Over a
year's time, less than 1% of people with intermittent claudication need to have
amputation for peripheral arterial disease that gets worse.1 People with diabetes are at increased risk for amputation.
Amputation is used only when the damage is very severe, possibly
life-threatening, and after all other treatment options have been tried.
In rare cases, a blood clot in an artery can suddenly and
completely block blood flow to a leg or foot. Often, severe pain, numbness, and
coldness develop within 1 hour. This blockage is an emergency. Clot-dissolving
medicines, surgical removal of the clot, or bypass surgery is needed to restore
blood flow.
