Summary
Venous leg ulcers (VLU) are the most common leg ulcer, can be painful, and limit work, lifestyles and activity, especially in older patients. There are few effective treatments - compression therapy (tight bandaging or stockings) helps healing, but about half the people with a VLU remain unhealed even after 12 weeks of treatment. Research suggests taking aspirin as well as using compression may speed up healing for VLU, but the current evidence is not enough to change clinical practice. We will conduct a randomised controlled trial to test whether using low dose aspirin (150 mg daily or placebo) really does speed up healing.
