In a patient with chronic venous insufficiency, what physical examination finding is most likely?

In patients with chronic venous insufficiency, the most prominent physical examination finding is lower extremity edema. This occurs due to the prolonged standing and increased venous pressure that characterize the condition, leading to fluid leakage from the capillaries into the interstitial space. As a result, the legs, particularly around the ankles, may become swollen and may also display other signs such as skin changes or varicosities.

The presence of edema is a direct consequence of inadequate venous return, which causes blood to pool in the veins and contributes to fluid accumulation in the tissues. This significant edema is often more marked after periods of inactivity or standing and can improve with elevation of the legs. Recognizing this clinical sign is crucial for diagnosing chronic venous insufficiency and guiding appropriate management strategies for affected patients.
