Advances in treatment and prevention of hepatorenal syndrome.
Hepatorenal syndrome (HRS) remains one of the major therapeutic challenges in clinical medicine today. The pathogenesis is complex, but the final common pathway seems to be that sinusoidal portal hypertension, in the presence of severe hepatic decompensation, leads to splanchnic and systemic vasodilatation and decreased effective arterial blood volume. Renal vasoconstriction increases concomitantly, renal haemodynamics worsens, and renal failure occurs. About 15 years ago it was shown that the renal failure is potentially reversible after liver transplantation. This potential reversibility together with increased understanding of the pathogenesis has led to successful preliminary attempts to reverse HRS nonsurgically with combinations of splanchnic vasoconstrictors and colloid volume expansion, insertion of trans-jugular intrahepatic portovenous shunt radiologically, and improved forms of dialysis. The aim of this chapter is to discuss the advances in the therapy of patients with HRS
