Most of the time, surgery is only done in cases of severe peripheral arterial disease (PAD), such as disabling intermittent claudication; open sores (ulcers that won't heal); or serious skin, bone, and tissue problems (gangrene).
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.
The methods of bypass surgery vary depending on the size of
the affected artery and where it is located.
- Peripheral Arterial Disease: Should I Have Surgery?
The type of surgery used to treat
PAD will depend on the location of the affected leg artery or
Endarterectomy is a less common surgery. It is typically done on the large femoral artery, which is in your groin and upper thigh area.
This surgery is done to remove fatty buildup (plaque) and to increase blood flow to the leg. This surgery is done by cutting open the femoral artery and removing the plaque. This surgery may be done by itself, or it may be done at the same time as bypass surgery or angioplasty.
What to think about
In rare cases,
peripheral arterial disease gets so bad that some people need to have a leg, a foot, or part of the foot amputated. 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.
Also 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
