Arterial Ulcer vs. Venous Ulcer: What’s the Difference?

Wounds on the lower legs can be painful and frustrating, especially when they refuse to heal. According to the American College of Surgeons, arterial and venous ulcers are among the most common types of non-healing wounds. Although both are types of leg ulcers, they have different causes and require distinct treatments. Proper diagnosis is key to determining the best course of action for healing these wounds.

Understanding the differences between arterial and venous ulcers can help you make informed decisions about your care and ensure that you receive the right treatment as soon as possible. If you suspect that you have a venous ulcer or any non-healing wound on your lower leg, it’s crucial to seek medical attention right away.

What Are Venous Ulcers?

Venous ulcers are the most common type of chronic wound, typically forming on the lower legs or ankles. These ulcers occur when the veins in the legs fail to return blood back to the heart efficiently, a condition known as chronic venous insufficiency. This leads to a buildup of pressure and fluid in the legs, which can cause the skin to break down and form an ulcer.

Symptoms of Venous Ulcers

• Appearance: Venous ulcers often have irregular, shallow edges and are accompanied by swollen, discolored skin.
• Location: Venous ulcers are most commonly located on the inside of the leg, near the ankle.
• Pain: They are typically less painful than arterial ulcers but may cause discomfort, swelling, and aching in the legs.

According to the National Institutes of Health (NIH), venous ulcers can be slow to heal, often taking several months of specialized care. Early diagnosis and treatment are essential for managing the underlying venous disease and speeding up healing.

What Are Arterial Ulcers?

Arterial ulcers, also known as ischemic ulcers, develop when there is insufficient blood flow to the lower limbs. This lack of blood flow, or ischemia, deprives skin and tissues of the oxygen they need, eventually leading to tissue death and open sores. Arterial ulcers are typically found on the feet, toes, or heels, and they often cause intense pain, particularly when the legs are elevated.

Symptoms of Arterial Ulcers

• Appearance: Arterial ulcers are usually small and have well-defined edges. The skin around them often appears thin, shiny, and hairless.
• Location: These ulcers typically form on pressure points, such as the ankles, toes, or heels.
• Pain: Unlike venous ulcers, arterial ulcers can be extremely painful, especially at night or when lying down.

People with conditions that reduce blood flow, such as atherosclerosis, diabetes, or peripheral artery disease (PAD), are at a higher risk for arterial ulcers. According to the Cleveland Clinic, managing these underlying conditions is essential for preventing arterial ulcers and their complications.

How to Tell the Difference Between Arterial and Venous Ulcers

Distinguishing between arterial and venous ulcers is crucial for getting the right treatment. However, because they both cause open wounds on the lower legs, it can be challenging for someone without medical training to identify the difference.

Here are a few key differences:

• Appearance: Arterial ulcers are smaller, rounder, and have a dry appearance, while venous ulcers are larger and often wet or weeping.
• Pain: Arterial ulcers are generally more painful, especially when the legs are elevated, while venous ulcers may cause aching or throbbing discomfort, particularly when standing.
• Location: Arterial ulcers are found on the toes, feet, or heels, whereas venous ulcers usually appear on the lower legs or ankles.

If your wound has not healed after four weeks, it’s important to seek medical attention immediately. Center for Vein Restoration can help you determine whether the ulcer is venous or arterial and recommend the best treatment plan.

Why Don’t Some Ulcers Heal?

Both arterial and venous ulcers can be difficult to heal without medical intervention. In many cases, the body needs help addressing the underlying causes, such as poor circulation or venous insufficiency. If left untreated, these ulcers can worsen and lead to complications like infection, tissue damage, or even amputation.

According to the Mayo Clinic, non-healing ulcers pose a high risk for infection, which can cause further damage to the skin and surrounding tissues.
