Mechanisms leading to circulatory and decreased kidney function in cirrhosis. The main mechanism is progressive splanchnic arterial vasodilatation due to overproduction of vasodilator molecules. During the initial phases of decompensated cirrhosis, when activation of vasoconstrictor systems is moderate, patients develop sodium retention and ascites. In subsequent stages, activation of antidiuretic hormone (ADH) leads to dilutional hyponatremia. Finally, in the most advanced phase, when circulatory dysfunction is extreme, renal vasodilatory systems are overcome and patients develop severe renal vasoconstriction and type 2 hepatorenal syndrome (HRS). Abbreviations: RAAS, renin–angiotensin–aldosterone system; SNS, sympathetic nervous system.
