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.
What is a characteristic of a venous stasis ulcer?
Venous stasis commonly presents as a dull ache or pain in the lower extremities, swelling that subsides with elevation, eczematous changes of the surrounding skin, and varicose veins. 2 Venous ulcers often occur over bony prominences, particularly the gaiter area (over the medial malleolus).
What should be included in the documentation of a venous stasis ulcer?
Document wound size, appearance, location, condition of surrounding skin, presence and characteristics of exudate, and signs and symptoms of infection.
How do you describe a leg ulcer?
A leg ulcer is a long-lasting (chronic) sore that takes more than 2 weeks to heal. They usually develop on the inside of the leg, just above the ankle. The symptoms of a venous leg ulcer include pain, itching and swelling in the affected leg.
What is a venous ulcer look like?
Shallow sore with a red base, sometimes covered by yellow tissue. Unevenly shaped borders. Surrounding skin may be shiny, tight, warm or hot, and discolored.
What do arterial wounds look like?
Arterial wounds typically have a “punched-out” look. They may be round in shape with well-defined margins — meaning the sore may be deeper in the skin than the surrounding area of healthy skin. In addition, you might have: There is little to no hair growth on the affected limb.
What are venous ulcers briefly describe the risk factors for venous leg ulcers?
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.
How can you tell the difference between arterial and venous ulcers?
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.
Which of the following characterizes an arterial ulcer?
Arterial ulcers are characterized by a punched-out look, usually round in shape, with well-defined, even wound margins. Arterial ulcers are often found between or on the tips of the toes, on the heels, on the outer ankle, or where there is pressure from walking or footwear.
What is a traumatic leg ulcer?
A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two.

What are the first signs of a leg ulcer?
- open sores.
- pus in the affected area.
- pain in the affected area.
- increasing wound size.
- leg swelling.
- enlarged veins.
- generalized pain or heaviness in the legs.
How do you dress a venous ulcer?
The first step is to remove any debris or dead tissue from the ulcer and apply an appropriate dressing. This provides the best conditions for the ulcer to heal. A simple non-sticky dressing will be used to dress your ulcer. This usually needs to be changed once a week.
How do you assess a venous ulcer?
- Take a history. Ask about: The duration of the ulcer. …
- Examine the person. Assess the ulcer. …
- Arrange investigations. Arrange a Doppler assessment of both legs to determine the ankle brachial pressure index (ABPI) to exclude arterial insufficiency.
Where do you assess for presence of venous ulcers?
Any of the lower leg veins can be affected. Venous ulcers commonly occur in the gaiter area of the lower leg. The most frequent location is the medial malleolus.
What is a characteristic of arterial insufficiency?
The most common symptoms of arterial insufficiency are related to problems in the arteries of the heart, brain and limbs. Peripheral arterial insufficiency often leads to pain, aching, numbness or cramping in the arms or legs. Symptoms related to the arteries of the heart include: Chest pain or pressure.
What does an infected leg ulcer look like?
Development of a red rash. Extremely dry or itchy skin near the open wound. Skin discoloration – skin will appear to develop a dark brown color. The fluid that appears to ooze from the wound – the fluid may have a foul smell to it.
What is a venous stasis?
Venous stasis involves an inflammation of the skin in the lower legs as a result of chronic venous insufficiency. If the valves or walls of the veins in the legs are not working properly, it is difficult for blood to circulate from the legs back to the heart.
What is the gaiter area?
Site & Appearance: Most venous ulcer occur in the “gaiter” area of the leg (i.e. area extending from just above the ankle to below the knee and tends to occur on both lateral and medial aspect of the leg), they are usually superficial with poorly defined margins.
What is the best treatment for venous stasis ulcers?
Evidence-Based Treatment Options. Compression therapy is considered the “gold standard” of care for prolonged treatment of venous ulcers. Compression therapy goals include edema management, venous reflux improvement, and enhanced healing. Compression therapy can consist of one layer to various layers.
What is the pathophysiology of venous stasis ulcers?
Venous stasis ulcers are caused by a problem in veins. Valves in the veins normally move blood in the right direction. When the valves fail, blood flows backward and pools in the veins. This pushes blood cells and fluid into nearby tissue.
Do you stage venous 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 difference between PAD and PVD?
Peripheral artery disease (PAD) is the name of one specific disease, a condition that affects only arteries, and primarily the arteries of the legs. Peripheral vascular disease (PVD) is a generic “umbrella term” that describes a large number of circulatory diseases.
Are arterial ulcers considered stasis ulcers?
Three (3) of these ulcer types are exclusively lower-extremity wounds located on the foot, ankle and lower leg: venous stasis ulcers, arterial ulcers, and diabetic neuropathic ulcers. Venous stasis ulcers, caused by venous insufficiency, account for approximately 75% of lower extremity ulcerations.
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.
What is a good abi?
An ABI ratio between 1.0 and 1.4 is normal. An ABI ratio between 0.9 and 1.0 is borderline. An ABI ratio of 0.9 or less means you have PAD.
Are there different types of leg ulcers?
The three most common types of leg and foot ulcers include: Venous stasis ulcers. Neurotrophic (diabetic) Arterial (ischemic ulcers)
Can leg ulcers lead to amputation?
Leg ulcers are serious. In fact, they can even lead to amputation. The good news is that, while leg ulcers can lead to amputation of part of the leg, these stubborn sores rarely lead to the loss of a foot or leg.
Should leg ulcers be covered?
occlusive (air- and water-tight) dressings – ulcers heal better when they are covered. These dressings should be changed weekly. compression treatment – boosts internal pressure, using either elasticised bandages or stockings.
What is neuropathic ulceration?
Neuropathic ulcers occur when a patient with poor neurological function of the peripheral nervous system has pressure points that cause ulceration through the epidermal and dermal tissue layers. This is a common condition in the foot, and occasionally other body parts.
What does the first stage of a leg ulcer look like?
The symptoms of a venous leg ulcer include pain, itching and swelling in the affected leg. There may also be discoloured or hardened skin around the ulcer, and the sore may produce a foul-smelling discharge. See your GP if you think you have a leg ulcer, as it will need specialist treatment to help it heal.
What ointment is good for leg ulcers?
Creams containing urea can also be helpful as urea is an excellent moisturiser. The skin around a leg ulcer can become macerated and damaged especially if the wound is exuding heavily. A barrier film such as Cavilon barrier film (3M) or LBF (Clinimed) protects the peri-wound skin and aids healing.
