September is Peripheral Artery Disease Awareness Month
Are you familiar with Peripheral Artery Disease (PAD)? According to the Society for Cardiovascular Angiography & Interventions, PAD is a common yet often under-recognized condition that affects more than 10 million Americans and is the leading cause of non-traumatic amputations in the United States.
With PAD, the arteries that supply blood to the limbs become narrowed or blocked due to atherosclerosis — a build-up of fatty deposits on the artery walls. This reduced blood flow can cause a range of symptoms, from leg pain during walking (claudication) to more severe complications such as non-healing wounds or ulcers.
“PAD often goes unnoticed in its early stages because its symptoms can be mild or mistaken for other conditions,” said Richard A. Young, DPM, a board-certified podiatrist at Penn Highlands Orthopedics and Sports Medicine and the Center for Wound Management. “However, if left untreated, it can lead to significant health problems. It is crucial to recognize the signs early and seek appropriate treatment.”
One of the most concerning aspects of this disorder is its effect on wound healing. The reduced blood flow associated with PAD means that wounds and ulcers in the legs and feet can become chronic and difficult to heal. Here's why:
- Reduced Oxygen and Nutrients: Blood carries oxygen and essential nutrients necessary for cell repair and wound healing. In PAD, the compromised blood flow means that these critical elements do not reach the wound site effectively.
- Impaired Immune Response: A diminished blood supply can also weaken the immune response in the affected area, making it harder for the body to fight off infections that can further impede healing.
- Increased Risk of Infection: Slow-healing wounds are more susceptible to infections, which can exacerbate the problem and lead to more serious complications.
- Complications: In severe cases, chronic wounds associated with PAD can lead to conditions like gangrene, potentially resulting in amputation if not managed properly.
“Understanding the risk factors of PAD, such as smoking, diabetes, high blood pressure and high cholesterol can help individuals take preventive measures,” said Dr. Young. “Just as important is recognizing the warning signs. Symptoms such as leg pain while walking, numbness, weakness, coldness in the lower leg or foot, or wounds on the toes, feet, or legs that won’t heal should never be ignored. Early detection makes a big difference, which is why regular check-ups are essential. For those with risk factors, routine visits with a healthcare provider can help monitor vascular health and catch concerns before they become serious.”
Adoption of a healthier lifestyle can significantly improve PAD management. Quitting smoking, maintaining a balanced diet, and engaging in regular exercise can enhance blood flow and overall vascular health.
Moreover, for those with PAD, proper wound care is essential. Keeping wounds clean, monitoring for signs of infection and seeking medical advice early can prevent complications.
The wound care experts at Penn Highlands Healthcare are dedicated to healing patients with chronic and difficult wounds, including those that are caused by circulatory problems that stem from diabetes, trauma, paralysis or burns. The clinical staff thoroughly assesses each patient’s chronic wound, including any underlying causes. After each assessment, the treatment plan is individualized to meet the specific needs of that patient. For more information, visit www.phhealthcare.org/woundcare
