#vessel wall permeability

• Angiorrhea — A continuous pathological discharge of fluid, plasma, or lymph from the lumen of structurally degraded or excessively permeable blood vessels or lymphatic vessels. In clinical and histopathological contexts, this well-defined exudation or transudation phenomenon often occurs in severe inflammatory states, endotoxic endothelial injuries, or advanced chronic lymphedemas, leading to fluid accumulation in interstitial tissues.
