edema

= accumulation of extravascular extracellular click and / or liquid in body cavities or tissues. Edema can occur localized and generalized.

nature

doughy, swollen, pale tissue

pathogenesis

intravascular (room in the blood vessels)	interstitium (space between cells)	intracellular (space inside the cells)
infirmity of the capillary membrane result: increased Wasserausstrom into the interstitium protein deficiency in the blood	transfer of lymph vessels

Clinical form of edema

1. inflammatory edema [through increased Kapillarwanddurchlässigkeit _{for H 2 O} and increase the colloid osmotic pressure caused by proteins in the tissue and increase the Capillary pressure caused by histamine]


2. 
   
   toxic edema [Kapillarwandschädigung by toxins, such as end-stage renal failure, etc.]


3. 
   
   mechanical edema [to transfer large lymphatic vessels (hence " lymphedema ) ; occurs locally after surgery with, for example Lymphgefäßentfernung]


4. 
   
   congestive edema [in obstruction of venous outflow, generally in heart failure]


5. 
   
   renal edema [Nierenkapillarschädigung by protein deficiency or increased salt retention]


6. 
   
   hunger edema / cachectic edema [by protein deficiency in the blood due to food shortage]


7. 
   
   edema due to liver damage [reduced albumin production, impaired lymphatic circulation in the liver, ie Lymph passes through the liver surface into the abdominal cavity, it comes to ascites ]


8. 
   
   Schwangerschaftsödem [Altosteron by increased release with a result of the increased salt retention in the kidney, the pressure of the uterus Pelvic & iliac vein, there is a congestive edema in the legs]
