TIPS and hepatic encephalopathy in patients with cirrhosis.

Despite a better understanding in its prognosis and pathogenesis, hepatic encephalopathy (HE) remains one of the major complications of Transjugular Intrahepatic Portosystemic Shunt (TIPS) with a prevalence ranging from 35 to 50%. Its epidemiology differs according to the indication for TIPS (salvage/rescue TIPS, preemptive (pTIPS) or elective TIPS). In salvage/rescue TIPS, the prognosis is linked to that of bleeding, and HE should not be a contraindication to TIPS, especially as bleeding is a common precipitating factor of HE.
