Topic Overview

The decision to have a limb amputated is difficult for the person and his or her doctor. Many times, extensive measures have been tried to save the limb. The major causes of amputation are diabetes and/or peripheral arterial disease that results in either painful, poor limb function or gangrene.

In general, amputation is recommended for:

Atherosclerosis: Your Arteries Age by Age

Atherosclerosis takes place over a lifetime. Complications from atherosclerosis tend to happen later in life. But the process of narrowing and hardening of the arteries starts early, progressing over decades. Developing some atherosclerosis is often unavoidable. It's the result of aging and our own genetic tendencies. A much larger part, though, is determined by our behavior and lifestyle choices as we move through life. How old are your arteries? Are they the ones you had in college? Or are...

  • Gangrene with or without infection.
  • Unbearable pain when at rest.
  • Nonhealing, untreatable ulcers.

Tobacco use may be the most important factor in progressing to amputation.

In doing the amputation, the surgeon seeks to remove all dead or dying tissue. Goals of amputation are to relieve pain, encourage wound healing, and increase a person's ability to carry out his or her daily activities.

Amputations and bypass grafting surgery may be planned at the same time to achieve the best results. For example, a person who has gangrene may have an amputation of part of the foot or leg while also having bypass grafting in an attempt to preserve still-living tissue. In a person who is not a candidate for revascularization or who has not had success with previous bypass grafting attempts, amputation alone may be recommended for severe pain at rest, nonhealing ulcers, and/or gangrene.

Preoperative issues in amputations

Preoperative care before amputation is similar to any major surgery. A complete history and physical exam, routine lab tests, a chest X-ray, and an electrocardiogram (EKG or ECG) may be performed.

People with major medical problems, such as diabetes or heart, lung, or kidney problems must be carefully assessed and their medical care optimized before the operation. The importance of the preoperative evaluation cannot be overemphasized. People who have amputations are often chronically or seriously ill. And their risk of dying around the time of the operation as well as in the following years is higher than for other people of the same age.

At which level should the amputation be done?

The appropriate amputation level depends on a number of factors, including why the amputation is needed, the general health of the person, the possibility for recovery and rehabilitation (rehab), and the probability of adequate wound healing. The aim of an amputation is to remove all dead and dying tissue while creating the most useful limb for recovery and rehab. It is very important to make sure that an artificial limb, if desired, can be appropriately fitted.
