A paracentesis is a medical "procedure in which fluid is withdrawn from a body cavity via a trocar and cannula, needle, or other hollow instrument."[1][2] A paracentesis usually refers to removing ascites.
Procedure
If a lower quadrant is used, inserting the needle lateral to the rectus muscle will avoid the inferior hypogastric artery.
Interpretation results
A serum-ascites albumin gradient (SAAG) of less than 1.1 g/dL lowers the probability of portal hypertension.[2]
