Intracellular Edema • energy (ATP) deficiency statuses – hydropic degeneration – vacuolar dystrophy • Na+/K+ dysbalances (hyperaldosteronism) • hypokalaemia in severe diarrhoea • hyperhydration - water intoxication (infusions!)
Starling´s Hypothesis Net filtration = Forces favoring filtration – Forces opposing filtration Forces favoring filtration: capillary hydrostatic preassure + intersticial oncotic pressure Forces opposing filtration: plasma oncotic pressure + tissue hydrostatic pressure
Edema Def.: accumulation of fluid in the intersticial spaces
Causes & Types of Edema • increased hydrostatic pressure - cardiac • decreased oncotic pressure –hypalbuminotic • blocked lymphatics – lymphostatic • neuromediators - allergic Extent: generalized, localized
Thrombosis Def.: intravital intravascular blood clotting Range: parietal obturative
Types of Thrombi • red stagnation • white fluxe • mixed • hyaline
RES • thrombosis • rheumatis • scurvy • cholelithiasis • appendicitis • Beiträge zur pathologischen Anatomie und zur allgemeinen Pathologie • Beiträge zur Thrombosenfrage Karl Albert Ludwig Aschoff 1866-1942, German
