Half of venous ulcers are attributed to which condition?

Venous ulcers are primarily associated with venous insufficiency, particularly involving the superficial venous system. When it comes to isolated superficial venous insufficiency, it is known that this condition can lead to increased venous pressures and eventually cause the formation of ulcers, particularly around the lower extremities.

In cases of isolated superficial venous insufficiency, the incompetent valves prevent proper blood flow back to the heart, resulting in stagnant blood and high pressure in the veins. This can lead to skin changes, ulceration, and ultimately ulcer formation, contributing to a significant proportion of venous ulcer cases. Understanding the link between venous insufficiency and the development of venous ulcers is crucial for effective diagnosis and management, highlighting the importance of addressing superficial venous issues to prevent ulcer formation.
