title: Minimally invasive Swine experimental model for the in vivo study of liver metabolism of drugs.
abstract: OBJECTIVE
  To develop a clinically relevant porcine model for the study of hepatic metabolism of drugs by means of hepatic vein catheterization.
  
  
  METHODS
  review of literature and elaboration of a hypothesis, design of an experimental method.
  
  
  RESULTS
  recent clinical studies were conducted by withdrawing cirrhotic patients' blood from right hepatic vein during hepatic vein pressure gradient measurements. Basing on our personal clinical experience and evaluation of research needs, an experimental model is proposed.
  
  
  CONCLUSIONS
  contemporary measurement of peripheral and hepatic concentration of drugs by peripheral vein and hepatic vein catheterization can be used to create a reliable and reproducible porcine model to study liver metabolism of drugs in vivo.
