What is defined as portal HTN?
What causes it?
↑ of hepatic venous pressure >5 mmg, due to cirrhosis.
Caused by:
- Cirrhosis causes: increased intrahepatic resistance to blood flow through the liver
- Increased splanchinic blood flow due to vasodilation
What is SAAG?
SAAG = serum ascites albumin gradient and it tells us what the etiology of the ascites is.
SAAG > 1.1 g/dL

How do we establish a diagnosis of ascites?
Abdominal US
We can then do a paracentesis (diagnostic and therepeutic) => run a SAAG to tell us the CAUSE of ascites.
SAAG <1.1 g/dL
Ascites is due to
- Hypoalbuminemia
- Diseased periteum
What electrolyte problem will people with ascites see?
Hyponatremia because free water excretion is impaired
What are our categories of causes of ascites?
What is the MCC of ascites?

- Cancer => could mean malignant ascites
- Fevers => could mean bacterial peritonitis (spont or secondary)
- immigant, immunocomproised, malnourish alcoholic: Tuberculosis peritonitis
PE on pt with ascites
