A patient with chronic venous insufficiency experiences significant leg edema. Which mechanism explains why compression stockings effectively reduce this edema, especially considering lymphatic system involvement?

💡 Explanation

Compression stockings increase external pressure, which enhances the interstitial fluid drainage into the lymphatic vessels, because this reduces fluid accumulation in the interstitial space. Therefore, edema is reduced, rather than increased arterial pressure or altered capillary permeability causing fluid shifts.
