Venous leg ulceration

Chronic venous leg ulceration is defined as an area of discontinuity of the epidermis, persisting for 4 weeks or more, caused by venous incompetence and associated venous hypertension (1)

• it is the most common form of leg ulcer and accounts for 60 to 80% of lower limb ulceration. In the UK, prevalence is estimated to be between 0.1% and 0.3% and many people experience recurrent episodes of prolonged ulceration (1)
• more common in women and older persons
• the condition imposes a heavy burden on the healthcare finances

Venous ulcers may be:

• primary - develop spontaneously as a result of venous hypertension
• secondary - secondary to an identifiable underlying cause e.g. - venous thrombosis or trauma) (2)
