Venous Ulcers Explained: Why They Occur and How to Manage Them

Venous Ulcers Explained: Why They Occur and How to Manage Them

Did you know that venous leg ulcers affect nearly 500,000 to 2 million people every year, and more than 50% of leg ulcers in the United States are classified as venous ulcers? ¹

These wounds may start small, but without timely treatment, they can become difficult to heal and may significantly affect mobility and quality of life. The good news is that with proper wound care, compression therapy, and lifestyle changes, venous ulcers can often be managed effectively and recurrence can be reduced.

In this blog, we’ll explain what venous ulcers are, why they occur, common symptoms to watch for, available treatment options, and practical tips to help prevent them from returning.

What Are Venous Ulcers?

Venous Ulcer, or Venous Stasis Ulcer, is a type of ulcer that occurs due to faulty veins that cannot return the blood in the leg back to the heart successfully. Such a condition leads to swelling of the area, skin damage, and ultimately the occurrence of a slow-healing sore known as an ulcer. They usually occur above the ankle bone. ²

Why Do Venous Ulcers Occur?

Venous ulcers form due to long-standing circulation problems in veins, particularly chronic venous insufficiency. Chronic venous insufficiency occurs where valves that control the blood flow in leg veins malfunction and as a result, blood collects in the lower legs, moving in a retrograde direction. ²

Other factors may be:

• Varicose veins
• Deep vein thrombosis
• Previous injury to the leg
• Weak calf muscles
• Prolonged standing/sitting
• Obesity
• Reduced movement

Over time, the increased pressure damages nearby tissues and skin, leading to ulcer formation.

Common Symptoms of Venous Ulcer

The common signs and symptoms include:

• Presence of an open wound close to the ankle or lower legs
• Swelling of legs or feet
• Legs feeling achy, heavy, or having a throbbing sensation
• Presence of brown, purple, or reddish skin discolorations
• Dry and itchy skin around the ulcer
• Crusting or drainage of fluid from the wound
• Foul odor due to infection of the ulcer
• Pain getting worse when you stay standing for longer durations

Some ulcers might appear shallow and be irregularly shaped with a reddish or yellowish bottom. ²

Who Is at Risk of Developing Venous Ulcers?

Various risk factors may raise your likelihood of developing ulcers in the veins:

• Older than 50 years
• Being overweight
• Pregnancy
• Smokers
• Diabetics
• High blood pressure
• Inactivity
• Having family history of vein problems
• Blood clots and varicose veins

Venous ulcers tend to occur more frequently in females than males. ²

How Are Venous Ulcers Diagnosed?

The diagnosis of venous ulcers often involves a variety of procedures ranging from physical examination and evaluation of your symptoms to circulation tests. In this process, the physician can examine your leg more carefully, check your medical history and ask about symptoms including edema, pain or any other changes of the skin on the affected area.

In order to have an idea about the state of your blood circulation, ultrasound tests may be recommended to evaluate the blood flow in your veins. The ankle-brachial index (ABI) test can show if the blood pressures are similar between the ankle and arm, which can give additional information about the possible circulatory problems. In case there are some signs of infection or poor healing of the wounds, you may be referred for further tests.

Thus, the use of these methods helps detect whether the disease is caused by venous insufficiency or some other vascular problem. ²

How To Treat Venous Ulcers?

Treatment of venous ulcers requires more than just dressing the wound. Key objectives during the process include improving blood flow, minimizing swelling, promoting wound healing, and ensuring the ulcer does not recur. The treatment will depend on the level of severity of the ulcers, the health state of the veins, and the patient. ²

Compression therapy is seen to be among the best methods of treating venous ulcers. Healthcare experts advise patients on using compression stockings and/or specialized bandages to provide compression on their legs. Compression enhances blood flow, reduces swelling and improves the rate of healing of the ulcers. ²

Use of compression therapy regularly can also minimize chances of recurrence of the ulcers. ²

Wound management is an essential process involved in treating the ulcers to ensure that infection does not occur. In accordance with the state of the ulcer, the following treatment measures will be applied:

• Cleaning the ulcer
• Changing of dressings frequently
• Debridement of the damaged tissues
• Protection from infection

Advanced wound care solutions may also be recommended as part of venous ulcer management to help maintain an optimal healing environment.

Procedures and Surgery

Should the aforementioned conservative treatments fail, more invasive procedures can be done to eliminate the problems with veins causing an ulcer. The treatments might include:

• Sclerotherapy to close the affected veins
• Endovenous ablation to deal with malfunctioning veins by using thermal or laser energy
• Vein surgery in case of severe venous disorder
• Skin grafting to treat larger ulcers

Addressing the root causes that lead to poor circulation is necessary to prevent recurrence of the ulcers in the future. ²

7 Prevention Tips for Venous Ulcers

The prevention of venous ulcers includes maintaining good circulation and decreasing pressure within the leg veins. Simple lifestyle modifications can assist patients to prevent the occurrence and recurrence of venous ulcers.

Here is a list of useful tips that one can adopt to prevent venous ulcers:

• Exercise regularly for promoting healthy blood flow.
• Maintain a normal body mass to avoid excess pressure within veins.
• Take breaks while sitting or standing for too long.
• Use compression stockings upon recommendation of a physician.
• Rest your legs often to decrease edema.
• Stop smoking to promote circulation.
• Control diabetes, hypertension, and high cholesterol.²

Final Thoughts

Venous ulcers are more than just slow-healing wounds, they are often a sign of underlying circulation problems that need proper attention and long-term care. While these ulcers can affect daily comfort and mobility, early diagnosis, consistent treatment, and healthy lifestyle changes can significantly improve healing outcomes and reduce the risk of recurrence. ²

Simple measures such as improving blood circulation, staying physically active, using compression therapy when recommended, and caring for the skin can go a long way in managing venous ulcers effectively. Most importantly, seeking timely medical guidance can help prevent complications and support faster recovery.

With the right treatment approach and ongoing care, many people with venous ulcers can successfully manage their condition and improve their overall quality of life.

Frequently Asked Questions

1. Can venous ulcers recover completely?

Yes, venous ulcers can recover with proper treatment and consistent care. However, they may return if the underlying vein problem is not managed properly. ²

2. How long does it take for a venous ulcer to recover?

Recovery time varies depending on the size of the ulcer, circulation problems, and overall health. Some ulcers may improve within weeks, while others can take several months. ²

3. Can compression stockings help venous ulcers?

Yes, compression stockings help improve blood flow, reduce swelling, and support faster recovery of venous ulcers. They may also help prevent ulcers from recurring. ²

4. How can you prevent venous ulcers from coming back?

You can help prevent venous ulcers by staying physically active, maintaining a healthy weight, elevating your legs regularly, quitting smoking, and using compression stockings if recommended by your doctor. ²
