What is a common feature associated with venous ulcers?

Venous ulcers are primarily associated with chronic venous insufficiency, which occurs when the veins struggle to send blood from the legs back to the heart. This inability leads to increased venous pressure, resulting in edema, impaired nutrient delivery to the tissues, and ultimately skin breakdown, which can develop into ulcers. The characteristics of venous ulcers typically include a shallow, irregular shape, located often around the ankles, and usually accompanied by symptoms such as swelling and hyperpigmentation of the surrounding skin.

High arterial perfusion, the presence of neuropathy, and normal venous pressure do not align with the characteristics commonly associated with venous ulcers. In fact, conditions such as normal venous pressure are contrary to the underlying pathophysiology of venous ulcers, where elevated venous pressure is a critical factor.
