Peripheral Artery Disease Q & A

What is peripheral artery disease?

Peripheral artery disease (PAD) develops when your arteries become clogged with plaque, which narrows and hardens them. This restricts your blood flow and causes a variety of problems. Peripheral artery disease usually affects your legs or arms, but can also develop in your abdomen and head. Some of the common signs of PAD include:

  • Leg cramping
  • Your feet, lower legs, hands, or arms are cold
  • Numbness and weakness in your extremities
  • Body hair and nail growth slows
  • Skin becomes shiny or discolored
  • Sores on your feet or legs don’t heal
  • Reduced pulse in your extremities
  • Erectile dysfunction in men

Your symptoms may be worse when you’re lying down or resting. Many patients say their pain and numbness interferes with their sleep.

What causes peripheral artery disease?

PAD and atherosclerosis develop when plaque builds up on the inside of your arteries. While your family history contributes to your risk of peripheral artery disease, other factors also increase your chances of developing the conditions. For example, you have a higher risk of peripheral artery disease if you:

  • Smoke
  • Have diabetes 
  • Have high blood pressure
  • Have high cholesterol
  • Are overweight or obese

Your risk of PAD also increases with age. If you have any of these symptoms, you should make an appointment to find out what’s causing them and get appropriate treatment. 

How is peripheral artery disease treated?

At ImageMed, Dr. Wood provides expert, customized treatments for PAD. He uses minimally invasive techniques with X-ray guidance to open your arteries and increase your circulation. 

All of Dr. Wood’s procedures are performed with catheters that he inserts through a tiny nick in your skin. He uses special X-rays to guide the catheter through your blood vessels to the blockage. Depending on your needs, he might perform angioplasty to gently put pressure on the inside of your arteries to widen them. Alternatively, Dr. Wood might perform atherectomy and send a laser fiber through the catheter to remove the plaque buildup. 

When your treatment is complete, Dr. Wood removes the catheter and covers the tiny incision. His minimally invasive procedures are safer and usually have shorter recovery times than traditional treatments for PAD.
