Risk Factors for Amputation in Peripheral Artery Disease

Monday, 12 April 2021 00:00

Peripheral artery disease (PAD) is a condition that causes poor circulation in the lower limbs due to the narrowing and hardening of the arteries that supply blood to this area. Left untreated, PAD can become progressively worse and lead to a variety of complications, up to and including amputation of the affected limb. Certain risk factors can make someone more likely to develop severe PAD that may require an amputation. Some of these include a history of cardiovascular disease, diabetes, and kidney disease, being 75 or older, or having an infected wound. If you are experiencing symptoms such as leg pain, numbness, or weakness, please consult with a podiatrist who can screen you for PAD, monitor your condition, and help you maintain the health of your feet and ankles.

Peripheral artery disease can pose a serious risk to your health. It can increase the risk of stroke and heart attack. If you have symptoms of peripheral artery disease, consult with Dr. Waymon Lewis from Weatherford Podiatry Clinic. Our doctor will assess your condition and provide you with quality foot and ankle treatment.

Peripheral artery disease (PAD) is when arteries are constricted due to plaque (fatty deposits) build-up. This results in less blood flow to the legs and other extremities. The main cause of PAD is atherosclerosis, in which plaque builds up in the arteries.


Symptoms of PAD include:

  • Claudication (leg pain from walking)
  • Numbness in legs
  • Decrease in growth of leg hair and toenails
  • Paleness of the skin
  • Erectile dysfunction
  • Sores and wounds on legs and feet that won’t heal
  • Coldness in one leg

It is important to note that a majority of individuals never show any symptoms of PAD.


While PAD occurs in the legs and arteries, Podiatrists can diagnose PAD. Podiatrists utilize a test called an ankle-brachial index (ABI). An ABI test compares blood pressure in your arm to you ankle to see if any abnormality occurs. Ultrasound and imaging devices may also be used.


Fortunately, lifestyle changes such as maintaining a healthy diet, exercising, managing cholesterol and blood sugar levels, and quitting smoking, can all treat PAD. Medications that prevent clots from occurring can be prescribed. Finally, in some cases, surgery may be recommended.
