Venous Leg Ulcer
Compression can be considered the cornerstone in the therapy of venous leg ulcers. As indicated by numerous studies, adequate compression supports venous ow and shows significant effects on deep venous hemodynamics – ultimately providing large improvements in pain, mobility and quality of life for the patient.
How do Venous Leg Ulcers develop?
Chronic venous disease is the underlying cause of a venous leg ulcer. The compromised blood ow to the heart is mainly caused by venous valve incompetence. The resulting reflux leads to an ambulatory venous hypertension which damages the capillaries making them more permeable. This allows uid, proteins and blood cells to leak into the tissues. As a consequence, an adequate support of nutrients and oxygen to the skin is reduced, causing death of skin tissue and the development of a venous leg ulcer.
Compression and stiffness factor
Adequate compression is necessary when venous ow is impaired. As venous valves are compromised, a sustained compression at the ankle of 40 mmHg3 or more is the recommended pressure to support venous return. At this point, the specific stiffness of a compression garment becomes a crucial factor. The higher the stiffness, the higher the working pressure and the effect of the muscle pump.
Compression provides the best conditions to heal the ulcer: the subsequent reduction of the local blood volume leads to lower venous re ux and the reduction of ambulatory venous hypertension.
People with Venous Leg Ulcer (VLU)
The chronic backup of blood due to unhealthy (incompetent) valves allows blood to pool in the lower leg, causing swelling. Chronic swelling interferes with the nutrition and oxygen supply to the skin. The skin becomes dry, flaky and darker in color. The skin is fragile and easily breaks with minor trauma, forming an open wound that becomes slow to heal.
Symptoms of venous ulcers:
- Swelling of the ankle and lower leg
- Skin discoloration around and above the ankles
- Open skin with moderate to heavy drainage
