Which of the following is a typical indicator of chronic venous disease?

Brawny edema is a typical indicator of chronic venous disease because it refers to a type of swelling that occurs due to the accumulation of fluid and the presence of hemosiderin deposits in the skin, resulting from venous hypertension. This condition often occurs in the lower legs and signifies long-term venous insufficiency, where blood is unable to efficiently return to the heart due to malfunctioning valves or other issues in the venous system. The skin may take on a brownish discoloration, which is characteristic of this type of edema related to chronic venous stasis.

In contrast, thinning of toenails is not specifically associated with chronic venous disease. It can indicate various other conditions, including malnutrition or peripheral vascular disease. Clubbing of the fingers generally indicates systemic issues such as heart or lung disease and is not a symptom of chronic venous insufficiency. Pallor in the extremities is more commonly associated with arterial insufficiency rather than venous issues, as it suggests reduced blood flow typically resulting from blockage or narrowing of the arteries. Therefore, brawny edema stands out as a hallmark sign of chronic venous disease.
