What Causes Slow Healing Wounds on Legs?
Leg wounds often go unnoticed, with many people assuming they will heal on their own. While this is true for most minor injuries, slow-healing wounds can be a cause for concern. For some people, these persistent sores may signal more serious underlying health issues that require immediate attention. Slow-healing wounds are especially concerning for individuals at risk for peripheral artery disease (PAD), as these persistent sores can often be the first indication of the condition. In this blog, we will discuss the various causes of slow-healing wounds, how to recognize them, and the important link between these persistent sores and peripheral artery disease PAD.
Understanding Slow Healing Wounds
A leg wound that has not shown significant improvement after four weeks can be considered slow healing. It’s important to note that everyone’s wounds heal differently, but certain signs can indicate a wound is healing more slowly than expected. Factors such as age, overall health, and underlying medical conditions can significantly influence the healing process. Specifically related to the legs, factors including poor circulation, diabetes, and infections can prompt slower healing, making it crucial to monitor any wounds closely.
The main reason that legs and feet are particularly vulnerable to slower healing wounds is their distance from the heart, which makes effective blood flow more challenging. As blood circulates through the body, it naturally encounters resistance, particularly in the lower extremities. This can result in reduced oxygen and nutrient delivery to the tissues, slowing down the healing process.
Signs of a Slow-Healing Wound
Recognizing a slow-healing wound early is crucial for receiving the appropriate, effective care. Common indicators include:
- Lack of improvement over time
- Increase in size or depth of the wound
- Persistent or worsening pain/discomfort
- Signs of an infection, such as redness, swelling, warmth, or discharge
The Connection Between Slow-Healing Wounds and Peripheral Artery Disease
PAD is a vascular condition that develops in the arteries. It stems from narrowed arteries due to plaque buildup, which ultimately leads to restricted blood flow. When the body experiences restricted blood flow, the legs and feet become particularly susceptible, leading to various complications, including pain, discomfort, and slow-healing wounds.
How PAD Contributes to Slow Healing
Because PAD leads to blockages in the arteries that cause decreased circulation, the essential nutrients and oxygen supply required to heal wounds becomes limited. As a result, patients with PAD may experience significantly delayed healing for leg wounds, and in some cases, these wounds may fail to heal altogether. PAD can make any injury to the legs more susceptible to infection and prolong healing times. This condition also affects the nerves, which can cause numbness or pain in the legs. Essentially, when a person with PAD is unaware of an injury or wound, they may fail to treat it properly, allowing for these wounds to worsen over time.
Risk Factors for PAD
Several factors can increase the risk of developing PAD, including:
- Age
- Medical history
- High blood pressure and cholesterol
- Smoking
- Diabetes
- Kidney disease
- Obesity
- Race
Treatment Options for PAD
Addressing slow-healing wounds requires a thorough evaluation to pinpoint and treat the underlying causes, making professional care essential. If PAD is identified as the source of your slow-healing wound, our expert vascular specialists at American Endovascular will develop a personalized treatment plan designed to restore blood flow and promote wound healing.
We offer several minimally invasive treatment options for peripheral artery disease, including:
- Angioplasty: Uses a small balloon to widen blocked arteries, improving blood flow and sometimes delivering medication directly to dissolve clots.
- Atherectomy: This procedure clears plaque buildup in challenging areas by using a precision catheter with advanced technology to restore artery health.
- Stent Placement: A small supportive tube is placed in blocked arteries to keep them open and strengthen artery walls for better circulation, especially to the legs and feet.
Proper wound management is also critical in your recovery efforts. Your physician will help guide you through the best steps for effective wound care, which may include:
- Cleaning the wound regularly
- Applying appropriate medications to the affected area
- Using antibiotics if an infection is present
- Monitoring progress and consulting with a vascular specialist
Lifestyle Modifications
Making significant lifestyle changes can positively impact your recovery. Your healthcare provider may prescribe medications to improve blood flow, manage pain, or treat underlying skin conditions contributing to slow healing. Adopting a balanced diet, regular exercise, quitting smoking, and proper wound care can further support your body’s healing process.
