A venous ulcer is a chronic leg wound caused by high pressure in the venous system. It is commonly associated with varicose veins and chronic venous insufficiency. Treating the surface wound alone is usually not enough if the underlying venous pressure continues.
How Can a Venous Ulcer Be Recognized?
- Wound around the ankle or lower leg
- Swelling and heaviness
- Brown skin discoloration
- Varicose veins
- Itching, eczema or hardened skin
- Drainage from the wound
Why Do Venous Ulcers Recur?
Recurrence is common when venous reflux, swelling and pressure are not controlled. A wound may close temporarily with dressings but reopen if the circulation problem remains.
How Is Diagnosis Made?
Doppler ultrasound is used to evaluate reflux in the superficial, deep and perforator veins. Arterial circulation should also be checked before compression treatment is planned.
Why Is Compression Important?
Compression reduces venous pressure and supports fluid return. It is one of the most important parts of venous ulcer treatment, but it must be selected correctly and used safely.
Are Dressings Alone Enough?
Dressings protect the wound and control moisture, but they do not correct venous reflux. If treatable reflux is present, endovenous treatment may be considered to support healing and reduce recurrence.
Home Care Points
- Use compression as instructed
- Elevate the leg during rest
- Walk regularly if allowed
- Do not apply unapproved creams or herbal products
- Seek care for odor, fever, increasing pain or redness
Frequently Asked Questions
Does a venous ulcer heal by itself?
It may improve temporarily, but recurrence is common without pressure control.
Are antibiotics always needed?
No. They are used when infection is present.
Can compression be used while there is a wound?
Often yes, but arterial circulation must be considered first.
