What You Need To Know
The cornerstone of treatment for venous leg ulcers is compression therapy, but dressings can aid with symptom control and optimise the local wound environment, promoting healing
There is no evidence to support the superiority of one dressing type over another when applied under appropriate multilayer compression bandaging
When selecting a dressing, look at the wound bed, edge and surrounding skin and decide on the goal of the dressing: for example, if there are signs of localised infection consider an antimicrobial dressing, if there is heavy exudate consider an absorbent dressing
A 65 year old man presents with a two month history of a wound in the gaiter area of his left leg. He has a history of a left leg deep vein thrombosis after a long flight but is otherwise fit and well. He had been self-managing with dressings bought over the counter, but the wound has gradually increased in size. The wound is not painful but is weeping serous fluid, causing irritation of the surrounding skin. Examination shows a 4×3×0.1cm wound above the left medial malleolus. There is haemosiderin deposition, venous flare, and moderate oedema in the limb. The ankle-brachial pressure index is normal at 1.0. He is diagnosed with a venous leg ulcer, which is managed with dressings and compression bandaging.
About 1% of the adult population in Westernised countries are affected by venous ulcers on the leg or foot.2 The prevalence increases with age to 1.7% in
Arterial And Venous Ulcers
Arterial ulcers make up approximately 20% of all foot and leg ulcers, and 70% are venous ulcers. Arteries are conducts that transport blood from the heart and spread in through all the bodys tissues. These tissues feed on the oxygen and nutrients brought to them in the blood.
Once the blood is used, it is filled with waste products, like carbon dioxide. This blood returns to the heart though the veins . When arterial blood does not circulate efficiently because the arteries have stretched, perhaps from arteriosclerosis for example, the blood begins to pool and tissues are affected. The majority of venous ulcers are caused because the valves that connect superficial veins with deep veins no longer function properly.
Arterial and venous ulcers usually affect the legs, the feet, the heels, and toes, and they can be very painful.

Treating An Infected Leg Ulcer
Sometimes an ulcer will produce a large amount of pus and become more painful, and some red inflammation may develop around the ulcer. These symptoms may be a sign of infection.
Cleaning of the ulcer should continue as usual and a dressing applied. Where possible, application of compression treatment should also be used. However, sometimes the leg may be too painful to allow this. Temporarily, compression can be reduced or avoided until the leg is more comfortable.You will be prescribed a seven-day course of antibiotic tablets to treat your infection. In most cases you will be given penicillin. If you are allergic to penicillin, an alternative antibiotic such as erythromycin can be used.
Side effects of antibiotics are usually mild and short-lived. They include:
If after treatment your leg pain has continued to worsen, you should inform your nurse because you may have developed a complication such as an infection.
Venous leg ulcers are often accompanied by oedema . This is effectively controlled with the use of compression bandages or graduated elastic medical compression stockings.
Keeping your affected leg elevated will also usually help ease any swelling. Try keeping your leg raised above hip level for 30 minutes, three or four times a day. Putting pillows or cushions under your feet when you are asleep may also help.
Venous ulcers most often form around the ankles.

Diagnosis Of Leg Ulcers
- examine the wound
- perform some tests to measure the blood flow in your lower leg, such as the ankle-brachial index. This test compares blood pressure readings taken at the ankle and at the arm using a device called a Doppler machine
- recommend an angiogram for an arterial ulcer, to find out if the artery needs surgery to clear the blockage.
What Treatment Might I Be Offered
Compression therapy if your wound isnt healing because of venous hypertension and there are no problems with the arterial blood supply to your legs, then you should be offered compression therapy. Compression therapy usually works very effectively and helps wounds to heal fast. It is thus essential to find a compression regime that is comfortable, provides the level of support you need and works. If this is inconsistently used or applied, this must be dealt with so that healing is not delayed
Compression therapy improves blood supply by applying pressure to the leg. This can be done by bandaging the lower leg or by wearing supportive socks, stockings or tights. To begin with it can be a little uncomfortable when you first start treatment but should not cause you any pain it should feel supportive to your leg. Any discomfort should reduce as the swelling goes down. If you do experience discomfort, talk to your nurse or doctor about it and they will advise you on ways of alleviating this.

Data Collection And Analysis
Two review authors independently performed study selection, ‘Risk of bias’ assessment and data extraction. We conducted this NMA using frequentist metaregression methods for the efficacy outcome the probability of complete healing. We assumed that treatment effects were similar within dressings classes . We present estimates of effect with their 95% confidence intervals for individual treatments focusing on comparisons with widely used dressing classes, and we report ranking probabilities for each intervention . We assessed the certainty of the body of evidence using GRADE for each network comparison and for the network as whole.
Critical Appraisal Of Individual Studies
The included HTA and SRs were critically appraised by one reviewer using AMSTAR and guidelines were assessed with the AGREE II instrument. Summary scores were not calculated for the included studies rather, a review of the strengths and limitations of each included study were described narratively.

What Types Of Wounds Can Alginate Dressings Heal
Alginate dressings usually do best on wounds that are actively giving out bodily secretions as the gel forms a shield around the sore to help soak up the secretions while keeping all other foreign bodies out of the cut, which lowers risks of infections. Alginate is also useful for wounds that are bleeding profusely as there are calcium fibers in the bandages which can break down and help slow the bleeding of a sore is bleeding heavily. Alginate dressings have long been used to dress wounds including fissures, hyper granulating tissue, interdigital maceration, heloma mole, and other lesions. Alginate dressings have also successfully been used to cover wounds on the parts of the body that are utilized the most such as on the feet. When it comes to healing venous ulcers, more studies are needed to see if Alginate dressings are effective.

What Are The Stages Of A Pressure Injury
There are four stages that describe the severity of the wound. These stages include:
- Stage 1: This stage is discolored skin. The skin appears red in those with lighter skin tones and blue/purple in those with darker skin tones. The skin does not blanch when pressed with a finger.
- Stage 2: This stage involves superficial damage of the skin. The top layer of skin is lost. It may also look like a blister. At this stage, the top layer of skin can repair itself.
- Stage 3: This stage is a deeper wound. The wound is open, extending to the fatty layer of the skin, though muscles and bone are not showing.
- Stage 4: This stage is the most severe. The wound extends down to the bone. The muscles and bone are prone to infection, which can be life-threatening.

Signs Of An Infection
A venous leg ulcer can be susceptible to bacterial infection. Symptoms of an infected leg ulcer can include:
A number of factors can increase your risk of developing a venous leg ulcer, including:
- obesity or being overweight this increases the pressure in the leg veins
- if you have difficulty walking this can weaken the calf muscles, which can affect circulation in the leg veins
- previous deep vein thrombosis blood clots that develop in the leg can damage valves in the veins
- varicose veins swollen and enlarged veins caused by malfunctioning valves
- previous injury to the leg, such as a broken or fractured bone, which may cause DVT or impair walking
- previous surgery to the leg, such as a hip replacement or knee replacement, which can prevent you from moving about
- increasing age people find it harder to move around as they get older, particularly if they suffer from arthritis
Wrap Systems Home Application And Treatment During The Coronavirus
A wrap system is a garment which you can wrap around your lower leg, thigh or foot to create compression. Weve previously mentioned the importance of compression this squeezes your leg tighter to help it heal. Wraps often have markers to guide you as to the degree you need to tighten them.
Things to remember:
- If you dont put your wrap on to the level of compression you need to have, it will not help the healing process for your wound
- If the wrap loosens as you move around during the day, you should tighten it to the level needed
The following video shows how to successfully apply and remove a wrap system.

Treating Venous Leg Ulcers With Honey Dressings Unlikely To Help Healing
- When compared with normal care, treating a leg ulcer with dressings impregnated with honey did not significantly improve the rate of healing, but did lead to a significantly increased number of reported adverse events, according to new research.
When compared with normal care, treating a leg ulcer with dressings impregnated with honey did not significantly improve the rate of healing, but did lead to a significantly increased number of reported adverse events, according to research published today in the British Journal of Surgery.
The breakdown in skin tissue below the knee that ends in venous leg ulcers forming has been recognised for centuries. Since the 17th century it has been treated by applying a compression bandage and we now know that this helps the leg cope with the constant pressure of fluids in lower parts of the body .
The current interest in alternative medicines has led to renewed interest in honey as a potential healing agent, and some people have suggested using honey dressings as well as a compression bandage.
âIn our trial the honey dressing did not significantly improve healing, time to healing, change in ulcer area, incidence of infection or quality of life,â says lead author Dr Andrew Jull who works in the Clinical Trials Research Unit at the University of Auckland.
What Is A Leg Ulcer
A leg ulcer describes a break in the skin, which allows air and bacteria to get into the leg. This is often caused by an injury, usually a minor one that cuts or grazes the skin.
In healthy people such an injury heals up quickly within a week or two. However, if the person has an underlying health problem, the skin does not heal and the area of breakdown can increase in size. This is what is meant by the term chronic leg ulcer.
All leg ulcers are a problem because they cause pain, disability and social isolation. In younger people, they can lead to time off work and sometimes loss of employment. All leg ulcers should be referred to a specialist team for assessment and treatment if they do not heal within 2 weeks.

There is full loss or damage of the skin. The wound looks quite deep but is still limited to the skin layers.
There is full loss or damage of the skin it is deep and goes all the way to the underlying bone, tendon or muscle.
How Long Does It Take For A Venous Ulcer To Heal
Most venous leg ulcers heal within 3 to 4 months if theyre treated by a healthcare professional trained in compression therapy for leg ulcers. But some ulcers may take longer to heal, and a very small number never heal. Treatment usually involves: cleaning and dressing the wound.
