Pathophysiology, diagnosis and treatment of ascites in cirrhosis

Abstract

Ascites is the most common complication of patients with cirrhosis; its development constitutes the first and most important manifestation of the disease and is an indication for liver transplantation. During the last decade significant advances have been made in regard to the pathogenesis and treatment of ascites. The description of a new hypothesis, the identification of new vasoactive factors involved in the pathogenesis of arterial vasodilation and the introduction of different therapeutic modalities (therapeutic paracentesis, transjugular intrahepatic portosystemic shunt, aquaretics drugs and liver transplantation) are all proof of this. Similarly, the description of predictive factors for the survival of patients with cirrhosis has been of major importance for the identification of candidates for liver transplantation. This chapter reviews current knowledge on the pathophysiology, diagnosis and treatment of ascites in patients with cirrhosis.
