Patient Education: Venous Stasis Ulcer Wound
What Is a Venous Stasis Ulcer?
A venous stasis ulcer is a sore that usually forms on the lower leg or ankle. It happens when blood does not flow properly back to the heart, causing pressure and fluid buildup in the veins. Over time, this pressure can break down the skin and form a slow-healing ulcer.
Causes of Venous Stasis Ulcers
Poor blood flow in the legs (venous insufficiency)
History of blood clots in the legs
Swelling or edema in the legs
Varicose veins
Obesity or lack of movement
Trauma or injury to the leg
Prevention
Elevate your legs above heart level several times a day.
Wear compression stockings as prescribed.
Avoid standing or sitting for long periods without moving.
Exercise your legs to improve circulation.
Keep skin clean and moisturized.
Check your legs daily for redness, swelling, or sores.
Treatment (as per your doctor’s order)
Clean the wound gently as instructed.
Cover the ulcer with a prescribed dressing.
Dressings may be changed daily or as directed.
Compression therapy may be used to reduce swelling.
Take prescribed medicines, such as antibiotics or pain medications.
Avoid walking barefoot or putting pressure directly on the ulcer.
What To Do if the Dressing is Compromised
A compromised dressing is wet, dirty, loose, or has fallen off.
Wash your hands before touching the wound.
Replace with a clean dressing if you have supplies.
If you cannot replace it, contact your home health nurse immediately.
If the wound is bleeding heavily, go to the emergency room.
Signs and Symptoms of Infection
Redness or warmth around the ulcer
Swelling in the area
Thick, yellow, or foul-smelling drainage
Fever or chills
Increased pain
Signs and Symptoms of Worsening Wound
Ulcer becomes larger or deeper
Edges of the wound pull apart
Skin around the ulcer breaks down
Wound does not show signs of healing after weeks
Diet for Wound Healing
Protein-rich foods: chicken, fish, eggs, beans, tofu
Fruits and vegetables: especially vitamin C-rich foods like oranges and strawberries
Whole grains for energy
Zinc-rich foods: seeds, nuts, lean meat
Drink plenty of water
⚠️ Important: If you have kidney problems, talk to your doctor or home health nurse before changing your diet. Some foods may not be safe.
When to Contact Your Home Health Nurse or Doctor
Dressing becomes loose, wet, or dirty
Mild redness, swelling, or drainage appears
Pain increases slightly
Questions about wound care, compression therapy, or diet
When to Go to the Emergency Room
Heavy bleeding that does not stop
Large amounts of pus or foul-smelling drainage
Fever with chills
Rapidly spreading redness
Severe pain not relieved by medicine
Signs of sepsis (confusion, rapid heartbeat, difficulty breathing)
Additional Information
Avoid putting pressure directly on the ulcer.
Always follow your compression therapy instructions.
Elevate your legs whenever possible to help circulation.
Avoid smoking as it reduces blood flow and slows healing.
