What is the typical shape of the leg affected by chronic venous stasis?

In chronic venous stasis, blood flow in the veins is impaired, leading to symptoms such as swelling, skin changes, and in some cases, ulceration. The affected leg often exhibits a specific shape due to this condition. The "bowling pin shape" typically describes a leg that is narrower at the top and significantly wider at the ankle, creating the appearance of a bowling pin. This pattern reflects the accumulation of fluid and tissue changes in the lower extremities caused by chronic venous hypertension.

This distinctive shape occurs as fluid buildup results in edematous legs, especially around the ankles, while the upper thigh remains comparatively unaffected. Understanding this aspect of venous stasis can help healthcare professionals recognize the condition and make appropriate interventions and management plans for affected individuals.
