What type of ulceration is associated with venous hypertension during leg dependency?

Chronic venous ulcers are primarily associated with venous hypertension that occurs during leg dependency, such as when an individual stands or sits for extended periods. This condition arises due to improper functioning of the venous valves, leading to increased pressure in the veins of the lower extremities.

When venous pressure rises, it can cause fluid to leak into the surrounding tissue, resulting in localized swelling and skin damage over time. This damage can lead to ulcers, particularly on the medial aspect of the lower leg. Chronic venous ulcers are often characterized by their irregular shape, shallow depth, and the presence of a ruddy granulation tissue, making them distinct from other types of ulcers.

In contrast, arterial ulcers are typically found on areas of lower blood flow, such as the toes or feet, and are not primarily linked to venous issues. Pressure ulcers develop from prolonged pressure on the skin often over bony prominences, while neuropathic ulcers result from loss of sensation, commonly in diabetic patients. Therefore, chronic venous ulcers remain the clear association with venous hypertension in dependency scenarios.
