Venous Stasis Ulcer Treatment

Your GP or practice nurse will ask whether you have any other symptoms associated with venous leg ulcers, such as:

  • swelling in your ankles
  • discoloured or hard skin

They’ll try to determine the cause of the ulcer by asking about underlying conditions or previous injuries, such as:

Deterrence And Patient Education

Individuals affected with VLUs can have an impaired quality of life, mainly related to disability. Plus, heavy exudates can cause malodor, social isolation, and emotional disturbances that severely impact life quality. Compliance is essential to achieve a successful outcome.

Patients should be educated because VLUs are chronic processes that require lifelong evaluation and care, even after wound closure. Additionally, conformity to diet and lifestyle modifications may reduce the risk or recurrence, but evidence is lacking.

What Types Of Venous Disease Cause Venous Stasis Ulcers

Chronic venous insufficiency is a common cause of valve dysfunction. It occurs when your valves are damaged or too weak to do their job.

Other venous ulcer causes include:

  • High blood pressure , which damages blood vessel walls.
  • Venous obstruction, a vein blockage thats sometimes due to blood clots.
  • Venous reflux, when blood flows backward through weak or damaged valves.

Signs Of An Infection

A venous leg ulcer can be susceptible to bacterial infection. Symptoms of an infected leg ulcer can include:

  • worsening pain

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

Symptoms Of Venous Insufficiency Ulcers

Venous Stasis Ulcer

Whe a venous ulcer begins to develop, stasis dermatitis may be present causing scaling and erythema of the lower extremities. Hemosiderin staining may also occur, causing the presence of brownish or yellow patches underneath the skin. Other skin changes may include the appearance of dark red or purple as a result of blood leaching into the surrounding tissue. Venous ulcers will present with shallow but large wounds with irregular margins that typically develop on the lower leg or ankle. The base of the ulcer is typically red, can result in a significant amount of exudate depending on the level of infection, and will ooze venous blood when manipulated. Typically the wound will be relatively painless, with any pain resulting from subsequent infection or edema. Often the entire leg will become swollen, and the skin will become more firm and reddish brown in color, otherwise known as stasis dermatitis. Elevation of the limb will help to relieve discomfort and swelling.

Cleaning And Dressing The 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.

Many people find they can manage cleaning and dressing their own ulcer under the supervision of a nurse.

What Causes Vascular Ulcers

Vascular ulcers can typically be grouped by their cause. However, it’s common for multiple conditions to cause an ulcer. An example of this is how diabetes can cause vascular ulcers.

  • Stasis ulcers. Caused by vein problems, these make up the majority of vascular ulcers. These are most common in your legs and feet as you age and happen because the valves in your leg veins cant do their job properly. This means they cant stop blood which should be headed upward to your heart from being pulled down by gravity. As a result, the excess blood in your legs and feet puts too much pressure on the blood vessels, which leak and burst. Over time, this can ulcers to develop.
  • Arterial ulcers. These are also called ischemic ulcers. These happen because of limited blood flow to an affected area, a problem called ischemia . The affected body part, usually a limb, slowly dies because of a lack of blood flow.

Treatment Options For Venous Stasis Ulcers

At first, venous ulcers are generally shallow and irregularly shaped. As the deterioration of the affected tissue progresses, the ulcer can extend deeper into the underlying tissues, involving the tendons, ligaments, and bone. The goal of venous ulcer treatment is to minimize edema, control infection, heal the wound, and prevent reoccurrence. Many leg ulcer patients experience alternating periods of healed and open ulcerations. Those with venous stasis ulcer commonly find the skin lesions will return unless the underlying cause is corrected.

To effectively treat venous stasis ulcers, doctors commonly evaluate the venous and arterial circulation in the affected area to identify the underlying cause. Once the cause is determined, physicians are in a better position to develop a successful plan of action. Doctors treating venous ulcers may recommend one or more of the following options:

Likewise, people ask, does venous stasis go away?

These venous stasis ulcers can be difficult to heal and can become infected. When the infection is not controlled, it can spread to surrounding tissue, a condition known as cellulitis. CVI is often associated with varicose veins, which are twisted, enlarged veins close to the surface of the skin.

Likewise, can exercise help venous insufficiency? Treatment for chronic venous insufficiencyExercise: Exercise helps pump blood through the legs and builds muscle that can promote better circulation. A doctor may also instruct a patient to elevate the legs above the heart three or four time a day for about 15 minutes at a time. This can help to reduce swelling.

Considering this, is walking good for venous insufficiency?

Your doctor may recommend that you walk, ride a stationary bicycle, or jog for 30 minutes several times a week. Being active helps improve circulation and tones muscles in your legs. This can help pump blood toward the heart. Stretching your calf and thigh muscles can also help improve blood flow.

Is venous insufficiency serious?

Vein disease is incredibly common â and manageable. However, if left untreated, venous insufficiency can cause far more serious complications like ulcers, bleeding, and a life-threatening condition called deep vein thrombosis .

Skin Grafts And Artificial Skin

Two layers of skin created from animal sources as a skin graft has been found to be useful in venous leg ulcers.

Artificial skin, made of collagen and cultured skin cells, is also used to cover venous ulcers and excrete growth factors to help them heal. A systematic review found that bilayer artificial skin with compression bandaging is useful in the healing of venous ulcers when compared to simple dressings.

Who Gets Foot And Toe Ulcers

Youre at higher risk for foot and toe ulcers if you are:

  • Native American.
  • Male.
  • Elderly.

If you have an eye, kidney or heart disease related to diabetes, youre also at a higher risk. About 15% of people with diabetes will get an ulcer, typically on the bottom of their foot. Around 6% of that 15% will have to be hospitalized because of complications.

Youre also at a higher risk of getting foot and toe ulcers if you have any of the following:

  • Problems with circulation.

Common Causes Of Stasis Dermatitis

Venous ulcer or venous stasis ulcer causes, symptoms, diagnosis &  treatment

Poor circulation causes stasis dermatitis. Typically, poor circulation is the result of a chronic condition called venous insufficiency. Venous insufficiency occurs when your veins have trouble sending blood to your heart.

There are one-way valves inside your leg veins that keep your blood flowing in the right direction, which is toward your heart. In people with venous insufficiency, these valves become weak. This allows blood to flow back toward the feet and pool in your legs instead of continuing to flow toward your heart. This pooling of blood is what causes stasis dermatitis.

Varicose veins and congestive heart failure are also known causes of leg swelling and stasis dermatitis.

Most of the conditions that cause stasis dermatitis usually develop in people as they get older. However, there are also several causes that are unrelated to age, including:

  • surgery, such as using a leg vein for bypass surgery

Ask your doctor about the types of skin creams and ointments you can use. Avoid using the following products:

  • lanolin
  • calamine and other lotions that dry your skin
  • topical antibiotic ointments such a neomycin, due to possible allergic reactions
  • benzocaine and other numbing medications

Your doctor might tell you to put wet bandages on your skin and might prescribe topical steroid creams and ointments. Your doctor may also prescribe antibiotics if your skin becomes infected. Surgery may be recommended to correct varicose veins if they become painful.

Making Healthy Lifestyle Choices

Maintaining a healthy lifestyle has a direct impact on vein health. A nutritious diet, regular exercise, maintaining a healthy weight, and following the recommendations of your health care provider can slow the progression of vein disease, ensure the successful outcome of vein treatment, and promote healing.

    What Is A Vascular Ulcer

    Vascular ulcers are wounds on your skin that develop because of problems with blood circulation. They are most common on your limbs especially your lower legs and feet but can also develop elsewhere on your body. These wounds can take a very long time to heal and may need specialized treatment, including surgery.

    Vascular ulcers can have two different causes. One is from poor circulation in your arteries, which provide nutrients and oxygen to the body. The other type of vascular ulcer is caused by poor circulation in your veins, which takes blood and waste products from the body and returns them to the heart. The most common type of vascular ulcer is a venous ulcer.

    How common are vascular ulcers?

    Vascular ulcers are very common, especially as people age. About 1% of adults in the U.S. have a vascular ulcer. For adults over the age of 65, it can be between 3% and 5%.

    Venous Ulcer Diagnosis And Treatment

    Doctors at Vascular surgeons at UPMC’s Heart and Vascular Institute use duplex ultrasound, a noninvasive test, to diagnose abnormal veins that cause venous ulcers. Part of the UPMC difference is that we actively look for the causes of the ulceration to treat venous pathology and keep the ulcer healed.

    After an evaluation of your veins, we recommend a treatment plan based on your needs:

    • Compression
    • Compression of the leg is vital to healing venous wounds.
    • Compression stockings are most commonly used for this treatment.
    • The pressure from the compression dressing counteracts the pressure from the veins of the leg and allows skin to heal.
  • Unna boots
  • A moist gauze applied around the lower leg, from the base of the toes to just below the knee.
  • This gauze then hardens to form a snug boot on the leg.
  • The support from the boot helps improve blood flow in the veins and heal the ulcer.
  • Transparent dressings
  • A clear, plastic-like film applied over the wound.
  • A support stocking is worn over the dressing to help hold it in place and improve circulation in the extremity.
  • Hydrocolloid dressings
  • A dressing applied over the venous ulcer to promote healing.
  • It also helps to remove any nonliving tissue from the wound .
  • Growth factors
  • Investigational medicines applied to the wound in the hope of promoting the growth of new tissue.
  • Surgery or vein ablation
  • Sometimes minor surgery or vein ablation is used to remove any nonliving tissue that keeps a wound from healing properly.

    Other Types Of Leg Ulcer

    Other common types of leg ulcer include:

    • arterial leg ulcers caused by poor blood circulation in the arteries
    • diabetic leg ulcers caused by the high blood sugar associated with diabetes
    • vasculitic leg ulcers associated with chronic inflammatory disorders such as rheumatoid arthritis and lupus
    • traumatic leg ulcers caused by injury to the leg
    • malignant leg ulcers caused by a tumour of the skin of the leg

    Most ulcers caused by artery disease or diabetes occur on the foot rather than the leg.

    Venous Stasis Ulcer Symptoms

    Venous Stasis Ulcers

    The development of an venous stasis ulcer is a serious medical condition that is usually preceded by a series of symptoms, including:

    • The development of stasis dermatitis, a condition usually observed in the lower legs and characterized by itchy skin, fluid retention, and noticeable changes in skin color and texture.
    • Swelling
    • A general heaviness in the limbs of the affected area.

    The venous stasis ulcer itself has several distinct characteristics, including:

    • Being a shallow sore with a red or purple base accompanied by the appearance of yellow, crust-like tissue around the perimeter of the sore
    • A brownish discoloration of the skin surrounding the venous stasis ulcer
    • The affected area being warm/hot to the touch
    • Localized pain
    • Oozing of pus

    Unlike most wounds of the skin, which tend to heal quickly, a venous stasis ulcer lacks the proper oxygen and nutrients required to support the natural healing process this often results in prolonged or poor healing and a significant increase in the risk of infection.

    What Is Venous Stasis

    Venous stasis is the swirling, slowing down or pooling of blood inside leg veins. This condition is also called venostasis. This pooling is a direct result of malfunctioning vein valves, sitting for too long or varicose veins. When malfunctioning vein valves are left untreated, and as it progresses, venous stasis can cause increasing pain and swelling in affected areas while also increasing the risk of blood clots and contributing to the formation of varicose veins, venous stasis ulcers, and stasis dermatitis.

    Most often observed in the legs, this condition is more common in people with chronic venous insufficiency and people who travel often.

    Venous Insufficiency And Venous Ulcers

    Venous insufficiency, also called venous reflux, is a debilitating leg issue in which the blood cant flow up through the veins toward the heart. Healthy veins contain a number of specialized, one-way valves that open to allow blood to flow upward and close to prevent blood from flowing back down. When these valves are damaged or malfunctioning, venous insufficiency occurs.

    As the valves deteriorate, the blood flows backwards and increases the pressure in the vein, dilating it. Blood stagnates, or pools, in the veins of the lower legs, putting pressure on the venous wall and causing inflammation and discomfort.

    In many patients, untreated superficial venous reflux leads to the deposition of red blood cells in the tissues. Hemoglobin, the protein in red blood cells that carries oxygen, and hemosiderin, the accumulation of iron from the breakdown of hemoglobin , leaves deposits in the skin in the form of dark staining.

    In severe cases, chronic, untreated venous insufficiency can cause open sores to develop on the skin, known as venous ulcers. These ulcers occur at the site where blood pools, due to the swelling that prevents the movement of nutrients and oxygen to the tissues.

    Venous insufficiency can also cause varicose veins, a condition in which the superficial veins, or the veins closest to the surface of the leg, enlarge, twist, or bulge. In addition to being unsightly, varicose veins can cause pain, discomfort, or the development of venous ulcers.
