Arterial ulcers develop as the result of damage to the arteries due to lack of blood flow to tissue. Venous ulcers develop from damage to the veins caused by an insufficient return of blood back to the heart. Unlike other ulcers, these leg wounds can take months to heal, if they heal at all.

What is an arterial ulcer?

Arterial wounds, also known as arterial ulcers, are painful injuries in your skin caused by poor circulation. ‌ Arterial ulcers typically happen when blood is unable to flow into the lower extremities, like the legs and feet.

What are arterial leg ulcers?

An arterial ulcer is an ulcer due to inadequate blood supply to the affected area (ischaemia). Arterial ulcers tend to occur on the lower legs and feet, and may be acute, recurrent or chronic. Ulcers may have multiple contributing factors; these ‘mixed ulcers’ constitute roughly 15% of all leg ulcers.

What is stasis ulcers in medical terms?

A stasis ulcer is a breakdown of the skin (ulcer) caused by fluid build-up in the skin from poor vein function (venous insufficiency). Fluid leaks from the veins into skin tissue when the blood backs up rather than returning to the heart through the veins.

Are arterial ulcers pale?

In addition, the base color of the extremity may turn red when dangled and pale when elevated. An additional sign of an arterial ulcer is delayed capillary return in the affected extremity. These ulcers are generally very painful, especially while exercising, at rest, or during the night.

What is the difference between arterial and venous insufficiency?

Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries. Left untreated, both conditions may lead to slow-healing wounds on the leg.

Do diabetics get venous or arterial ulcers?

Leg and foot ulcers in diabetic patients have three common underlying causes: venous insufficiency, peripheral neuropathy (neurotrophic ulcers), or peripheral arterial occlusive disease.

Do you stage stasis ulcers?

Venous stasis ulcers are the end stage of chronic venous insufficiency. In order to treat venous stasis ulceration, one must have a clear understanding of the pathophysiology of venous disease. Most of the vein problems that occur are due to increased pressure in the venous system.

What is the difference between venous and arterial ultrasound?

A venous ultrasound of the upper or lower extremities provides pictures of the veins and the blood flow within the veins of the arms or legs. An arterial ultrasound of the upper or lower extremities provides pictures of the arteries and the blood flow within the arteries of the arms or legs.

Is venous ulcer same as stasis ulcer?

These ulcers usually form on the sides of the lower leg, above the ankle and below the calf. See a picture of areas affected by venous skin ulcers. Venous skin ulcers are slow to heal and often come back if you don’t take steps to prevent them. A venous skin ulcer is also called a stasis leg ulcer.

Article first time published on

What is a stasis ulcer caused by?

Stasis ulcers are caused by: Venous insufficiency (poor return of venous blood from the peripheries to the central circulation) Venous hypertension (high pressures within the veins) Oedema (accumulation of fluid in the lower limbs).

How do you treat an arterial ulcer?

Treatment of arterial ulcers may involve surgical intervention for angioplasty, stenting, bypass grafting and, ultimately, amputation. Pain control is an important aspect of the management of arterial ulcers. Adequate analgesia is required to manage the severe ischaemic pain often experienced with arterial ulcers.

What are the different types of leg ulcers?

• Venous stasis ulcers.
• Neurotrophic (diabetic)
• Arterial (ischemic ulcers)

How can you tell the difference between a venous and arterial ulcer?

In venous disease, ulcers are usually located in the gaiter area between the ankle and the calf, often on the medial aspect of the leg. Arterial leg ulcers occur as a result of reduced arterial blood flow and subsequent tissue perfusion.

Can you compress arterial leg ulcers?

In patients with arterial leg ulcers, properly applied compression therapy using increased pressure over the wound may lead to an improvement of the arterial flow and to complete healing.

Where are venous stasis ulcers located?

Commonly located on the ankle or calf, venous stasis ulcers are painful and red in color but may be covered with a yellow, fibrous tissue and an irregular border. Drainage and discharge are possible with venous stasis ulcers. This type of ulcer is common in patients with a history of leg swelling or varicose veins.

What type of ulcer is diabetic foot?

What Is a Diabetic Foot Ulcer? A diabetic foot ulcer is an open sore or wound that occurs in approximately 15 percent of patients with diabetes, and is commonly located on the bottom of the foot. Of those who develop a foot ulcer, six percent will be hospitalized due to infection or other ulcer-related complication.

Is a diabetic foot ulcer the same as a pressure sore?

Diabetic ulcers may look similar to pressure ulcers; however, it is important to note that they are not the same thing. As the name may imply, diabetic ulcers arise on individuals who have diabetes, and the foot is one of the most common areas affected by these skin sores.

How are arterial ulcers diagnosed?

Physical assessment should include both a general exam, looking for problems relating to lungs, heart and nervous system, and a focused exam of the affected extremities and arterial pulses. Vascular laboratory findings can also help confirm a diagnosis of arterial ischemic ulceration.

Are arterial ulcers painful?

Arterial ulcers are often very painful, they are often on the foot, around the ankle, sometimes the lower leg. The pain from them can be worse at night, and patients hang the leg out of bed or sleep in a chair to get relief from this night pain.

How do venous stasis ulcers form?

A venous leg ulcer can develop after a minor injury if there’s a problem with the circulation of blood in your leg veins. If this happens, pressure inside the veins increases. This constant high pressure can gradually damage the tiny blood vessels in your skin and make it fragile.

What is the difference between a blood vessel and an artery?

‌Arteries and veins (also called blood vessels) are tubes of muscle that your blood flows through. Arteries carry blood away from the heart to the rest of the body. Veins push blood back to your heart. You have a complex system of connecting veins and arteries throughout your body.

What are the symptoms of a blocked artery in your leg?

• Painful cramping in one or both of your hips, thighs or calf muscles after certain activities, such as walking or climbing stairs.
• Leg numbness or weakness.
• Coldness in your lower leg or foot, especially when compared with the other side.
• Sores on your toes, feet or legs that won’t heal.

What does arterial ultrasound show?

Ultrasound is a procedure that uses sound waves to “see” inside your body. An arterial duplex ultrasound uses sound waves to create a color map of the arteries in your legs to identify: Narrowing of your vessels that may be causing leg pain when walking. Resting leg pain.

What are the 6 types of wounds?

• Penetrating wounds. Puncture wounds. Surgical wounds and incisions. Thermal, chemical or electric burns. Bites and stings. Gunshot wounds, or other high velocity projectiles that can penetrate the body.
• Blunt force trauma. Abrasions. Lacerations. Skin tears.

What is the difference between a pressure ulcer and a non pressure ulcer?

Non-pressure chronic ulcers are similar to pressure ulcers in that they require documentation of the site, severity and laterality. Category L97 and L98 are for non-pressure ulcers, and have an instructional note to code first any associated underlying condition, such as: Associated gangrene.

What are the classification of wounds?

Surgical wound infection control began in the 1960s in the United States with the classification of wounds into four categories (clean, clean-contaminated, and dirty or infected) and with surveillance reports from Cruse and Foord.

How do you describe a venous stasis ulcer?

A venous stasis ulcer is wound on the skin. It is due to a pooling of blood in the veins. These ulcers happen most often on the legs. If left untreated, the ulcers can lead infection and other serious problems.

How do you prevent stasis ulcers?

1. Avoid smoking.
2. Lose weight if you’re overweight or obese.
3. Stay at your ideal weight.
4. Get plenty of regular exercise.
5. Move around often.
6. Raise (elevate) your legs for a short time, especially if you’ve been standing all day.

Can you Debride an arterial ulcer?

It is not appropriate to debride arterial ulcers as this may promote further ischaemia and lead to the formation of a larger ulcer. ​ Choice of wound dressings will be dictated by the nature of the wound. Vasoconstrictive drugs such as non-selective β blockers should be avoided.

Are ischemic ulcers painful?

Wound may or may not be painful. Skin on the leg appears shiny, tight, dry, and hairless. Dangling the leg down off the side of a bed or chair causes the leg to turn red. When you raise the leg, it turns pale and cool to touch.
