Which condition is swelling caused by obstruction of lymphatic vessels?

Swelling from obstruction of lymphatic vessels is due to impaired drainage of interstitial fluid and proteins by the lymphatic system. When the lymphatics are blocked or damaged, fluid accumulates in the tissue, producing edema that is often localized to the area drained by the affected vessels and can become thickened over time due to ongoing protein-rich fluid in the interstitium. This distinguishes it from edema caused by venous obstruction, which arises from increased capillary hydrostatic pressure pushing fluid into tissues and tends to vary with posture and activity. Dehydration involves fluid loss, not accumulation, and anasarca refers to generalized, widespread edema from systemic causes. Therefore, the swelling caused by lymphatic obstruction is lymphedema.
