What is an arterial ulcer?

An arterial ulcer is a type of skin ulcer that is caused by a problem with the arteries, which are the blood vessels that carry oxygen and nutrients to the tissues of the body. Arterial ulcers typically occur on the legs, but can also develop on the feet, arms, or other parts of the body.

Arterial ulcers are often caused by a condition called peripheral arterial disease (PAD), which is a narrowing or blockage of the arteries in the legs. PAD can occur due to a buildup of plaque, which is made up of cholesterol, fat, and other substances. Plaque can narrow the arteries and restrict blood flow to the legs, leading to the development of arterial ulcers.

Arterial ulcers can also be caused by other conditions that affect the arteries, such as diabetes, high blood pressure, and smoking. These conditions can damage the arteries and make them more likely to develop blockages.

Symptoms of an arterial ulcer include:

* A painful, open sore on the skin

* Red, swollen, and warm skin around the ulcer

* Throbbing or aching pain in the leg or foot

* Difficulty walking or standing

* Pale or bluish skin

* Hair loss on the leg or foot

* Cool or cold skin

If you have any of these symptoms, it is important to see a doctor right away to get a diagnosis and treatment. Treatment for arterial ulcers may include medications, surgery, or lifestyle changes.
