Arterial Ulcers
Arterial ulcers are wounds that develop when there isn’t enough blood flow to deliver oxygen and nutrients needed for the skin to heal. They’re most often caused by peripheral artery disease (PAD) and commonly appear on the toes, feet, heels, or along pressure points on the lower leg. Because circulation is limited, these ulcers can be slow to heal and may become increasingly painful—especially at night or when the leg is elevated.
At Coastal Vascular Center, we focus on identifying the underlying circulation problem and restoring blood flow when needed, so the wound has the best chance to heal. If you have a sore on your foot or leg that isn’t improving, or you’re experiencing pain, color changes, or coldness in the foot, a vascular evaluation can help prevent complications and protect long-term limb health.
Arterial Ulcers: What You Should Know
Arterial ulcers and other vascular ulcers are chronic wounds that develop due to impaired blood circulation, most commonly affecting the lower extremities such as the legs and feet. Arterial ulcers are painful injuries in the skin caused by poor circulation. These ulcers are broadly categorized into arterial ulcers (also known as ischemic ulcers) and venous ulcers, each with distinct causes and characteristics. Arterial ulcers result from arterial insufficiency, where narrowed or blocked arteries—often due to peripheral arterial disease (PAD)—reduce blood flow and oxygen delivery to tissues. Peripheral arterial disease (PAD), a condition where narrowed arteries reduce blood flow to the limbs, is a common underlying cause of arterial ulcers. This lack of circulation can lead to tissue death, open wounds, and, if left untreated, severe complications like amputation of the affected limb.
This guide is intended for patients, caregivers, and healthcare professionals seeking to understand, prevent, and treat arterial ulcers. Early recognition and treatment of arterial ulcers are crucial to prevent serious complications such as infection and limb loss.
Venous ulcers, in contrast, are caused by problems in the leg veins that prevent blood from efficiently returning to the heart, leading to increased pressure and fluid buildup in the lower legs. Both types of vascular ulcers are influenced by underlying conditions such as high blood pressure, diabetes mellitus, and poor circulation. Recognizing the underlying cause of these ulcers is essential for effective treatment and prevention, as addressing issues like blood pressure, diabetes, and overall blood circulation can significantly reduce the risk of developing these serious wounds. At Coastal Vascular Center, our team specializes in diagnosing and treating the full spectrum of vascular ulcers, helping patients restore healthy blood flow and prevent complications.
Causes of Arterial Ulcers
Addressing the causes of arterial ulcers requires a multifaceted approach, focusing on improving blood circulation, managing underlying conditions such as diabetes and hypertension, and adopting healthier lifestyle choices to mitigate risk factors. At Coastal Vascular Center, our specialized care team offers tailored treatment plans to tackle the root causes of arterial ulcers, prioritizing patient outcomes and quality of life.
Arterial ulcers, a severe and painful manifestation of vascular disease, arise from a complex interplay of factors that disrupt normal blood circulation. Understanding these ulcers’ root causes is pivotal in preventing their onset and addressing the underlying problem effectively. The primary cause of arterial ulcers is inadequate blood flow to the tissues, often a consequence of Peripheral Arterial Disease (PAD), which commonly affects the lower limb arteries. Peripheral arterial disease (PAD) is a common underlying condition that leads to the development of arterial ulcers. Endothelial dysfunction, particularly in patients with diabetes mellitus, contributes to impaired blood flow, impaired angiogenesis, and the development of arterial ulcers. Heart disease is another contributing condition that can worsen arterial disease and increase the risk of arterial ulcers. Here’s a closer look at the various factors contributing to this condition:
Atherosclerosis
Atherosclerosis, characterized by cholesterol accumulation in blood vessel walls, is a primary cause of arterial ulcers. This condition involves the accumulation of plaque—a mixture of fat, cholesterol, and other substances—on the walls of arteries, causing them to narrow and harden. As the arteries become more restricted, blood flow to extremities, such as the legs and feet, diminishes, increasing the risk of ulcer formation.
Hypertension and Diabetes
Both hypertension (high blood pressure) and diabetes are significant risk factors for the development of arterial ulcers. Hypertension can damage blood vessels over time, while diabetes, particularly when uncontrolled, can lead to poor circulation and nerve damage. These conditions exacerbate the effects of atherosclerosis, further limiting blood flow.
Smoking and Other Lifestyle Factors
Smoking is a major risk factor for arterial ulcers due to its adverse effects on blood circulation and artery health. Nicotine causes arteries to constrict, while the chemicals in cigarette smoke can damage the lining of the arteries, accelerating atherosclerosis. Obesity and a sedentary lifestyle also contribute to the development of arterial ulcers by increasing the risk of hypertension, diabetes, and atherosclerosis.
Trauma and Injury
In individuals with compromised circulation, minor injuries or trauma to the legs or feet can escalate into arterial ulcers. The diminished blood flow hampers the body’s natural healing process, preventing wounds from healing appropriately and leading to ulcer formation.
Age and Genetic Factors
Increasing age is associated with a higher risk of atherosclerosis and PAD. Additionally, genetics can play a role; individuals with a family history of vascular disease may be more prone to developing arterial ulcers.

Risk Factors for Arterial Ulcers
Arterial ulcers are complex conditions with multiple contributing factors. While the direct cause of these ulcers is inadequate blood flow due to peripheral arterial disease (PAD), several risk factors increase the likelihood of their development. Recognizing these risk factors is crucial for prevention and early intervention. Here are the key risk factors associated with arterial ulcers:
- Smoking: The consumption of tobacco products is one of the most significant risk factors for arterial ulcers. Smoking damages the blood vessels, leading to decreased blood flow and an increased risk of plaque buildup in the arteries (atherosclerosis), directly contributing to the development of PAD and subsequent arterial ulcers.
- Diabetes: Individuals with diabetes are at a higher risk of developing arterial ulcers due to the disease’s impact on blood circulation and nerve function. High blood sugar levels can damage blood vessels over time, reducing blood flow to the limbs and impairing wound healing. Diabetes also increases the likelihood of nerve damage (neuropathy), making individuals less aware of injuries and infections that could lead to ulcers.
- Hypertension (High Blood Pressure): Hypertension can cause harm to arteries and is a known factor in the progression of atherosclerosis, thereby indirectly increasing the risk of arterial ulcers by reducing blood flow to the extremities.
- High Cholesterol: Elevated levels of cholesterol contribute to the buildup of fatty deposits in the arteries, narrowing them and limiting blood flow to various parts of the body, including the legs and feet. This condition, known as atherosclerosis, is a direct contributor to the risk of developing arterial ulcers.
- Age: The risk of arterial ulcers increases with age, particularly in individuals over 60. Aging is associated with a natural decline in the efficiency of the vascular system, including the arteries, which can exacerbate the effects of other risk factors for arterial ulcers.
- Sedentary Lifestyle: A lack of physical activity can contribute to several conditions, such as obesity, diabetes, and hypertension, that are risk factors for arterial ulcers. Regular exercise can improve blood flow and overall vascular health, reducing the risk of ulcers.
- Family History and Genetics: A family history of vascular disease, including PAD, can increase an individual’s susceptibility to arterial ulcers. Genetic predispositions play a role in the development of many conditions associated with arterial ulcers.
Understanding and mitigating these risk factors through lifestyle changes and medical intervention is essential in the prevention of arterial ulcers. Incorporating regular exercise, maintaining a healthy diet, quitting smoking, and managing existing health conditions like diabetes and hypertension are critical steps in reducing the risk. At Coastal Vascular Center, our team is dedicated to providing personalized care and education to help patients navigate these risk factors, aiming to prevent the occurrence of arterial ulcers and improve overall vascular health.
Understanding these risk factors can help with early recognition of symptoms, which is crucial for timely intervention.
Symptoms of Ulcers
The symptoms of vascular ulcers can vary depending on whether the ulcer is arterial or venous in origin, as well as the severity of the underlying vascular disease. Below is a quick comparison of the distinguishing features of arterial ulcers and venous ulcers:
- Arterial Ulcers:
- Typically have a “punched-out” appearance
- Usually extremely painful, especially when the affected area is elevated or during activity
- Most often found on the toes, feet, or lower leg
- The surrounding skin may look pale, thin, and shiny, with little to no hair growth
- Tissue may feel cool to the touch due to poor blood flow
- In severe cases, the skin around the ulcer may become necrotic or blackened
- Arterial ulcers typically have a ‘punched-out’ appearance and are usually extremely painful
- Venous Ulcers:
- Tend to have irregular, shallow edges
- Often less painful than arterial ulcers and are often painless unless infected
- Usually develop on the lower leg, particularly around the inner ankle
- The surrounding skin may appear swollen, discolored, or hardened, often due to underlying venous insufficiency
- May notice swelling, warmth, or redness in the affected area
- Wounds may ooze or develop a foul odor if infection sets in
Early recognition of these symptoms is crucial, as prompt treatment can help prevent complications such as infection, tissue loss, or even amputation. If you notice any persistent wounds, pain, or changes in the skin of your lower legs or feet, it’s important to seek evaluation from a vascular specialist.
Treatment for Arterial Ulcers
At Coastal Vascular Center, we understand the necessity of treating the root cause—poor arterial blood supply. Without addressing it, ulcers may take an extended period to heal or may never heal at all. Arterial ulcers at Coastal Vascular Center are treated using medical dressings, creams, and ointments to stimulate healing and protect the ulcer from infection.
Simultaneously, we are dedicated to conserving the limbs by treating arterial ulcers and Peripheral Arterial Disease (PAD) medically. Medications are used to manage high cholesterol, control blood pressure, reduce walking pain, and prevent plaque buildup or blood clots formation.
We also employ minimally invasive interventional radiology procedures, such as angioplasty for treating peripheral artery disease, which involves unblocking the arteries using a medical balloon to promote better blood flow. In other instances, arteries are kept open using a stent—a small metal cylinder. This involves placing a stent in the arteries or veins to keep them open and blood flowing. We also utilize atherectomy, which involves shaving plaque from the inside of the artery using a small catheter at the site of the blockage and removing it from the patient’s body.
In severe cases of peripheral arterial disease, our team will work with you to provide the best treatment. This may mean performing surgery to remove blockages or create bypasses around the clogged areas. Understanding the severity of arterial ulcers and the need for specialized care is essential.
