Peripheral Artery Disease (PAD) is a serious circulatory condition in which the arteries that supply blood throughout the body become completely or partially blocked. This blockage is caused by fatty plaque deposits that harden arteries, called atherosclerosis, and significantly impair blood flow. The most common type is lower-extremity PAD, where there is a reduction in blood flow to the legs and feet. When left untreated, PAD can lead to gangrene or even limb loss1.
PAD affects more than 12 million Americans. In fact, one in five people over the age of 60 are living with PAD. PAD increases the risks of hard-to-heal wounds by obstructing circulation to the legs. Risk factors for PAD include smoking, advanced age, vascular disease and diabetes. Although the long-term effects of PAD are serious, an astonishing 40 percent of people with PAD do not experience any symptoms.
OSF Wound Care a member of the Healogics® network, provides specialized wound care and non-invasive tests, including a painless Doppler ultrasound, which evaluates blood flow in arteries near the wound, helping identify circulation issues and potential blockages. When appropriate, an ankle-brachial index (ABI) test may also be performed. This approach to early detection and assessment of PAD can help prevent complications and reduce amputation risks.
The following are the signs and symptoms of PAD:
- Pain or cramps in the back of the leg while walking or exercising
- Lower legs and feet that are cool to touch or that have shiny skin
- Legs and feet appear pale when raised and bluish/purplish when hanging down
- Numbness or tingling in the feet and legs
- A sore or wound on the toes, legs or feet that does not heal
Advanced PAD results in impaired wound healing and a greater risk for limb loss. Twenty-five percent of those with advanced PAD may require an amputation within one year. People who are at risk for PAD should call OSF Holy Family Wound Care if they develop a wound that is slow to heal. The specialized treatment provided by OSF Holy Family Wound Care may accelerate healing times, boost healing rates and significantly diminish amputation risks.
