Combined Spontaneous Portosystemic Shunt Embolization and Transjugular Intrahepatic Portosystemic Shunt Creation for Treatment of Hepatic Encephalopathy.

ABSTRACT

This retrospective case series assessed the early effectiveness of combined spontaneous portosystemic shunt (SPSS) embolization and preemptive transjugular intrahepatic portosystemic shunt (TIPS) creation for alleviation of medically refractory hepatic encephalopathy (HE) and prevention of portal hypertension complications in patients with liver cirrhosis. Eight patients with liver cirrhosis (5 men and 3 women; mean age, 61 years [SD ± 10]) and HE (overt [West-Haven Grade 2-4], n = 7; covert [West-Haven Grade 1], n = 1) refractory to lactulose and rifaximin therapy who underwent concurrent or staged SPSS embolization and TIPS creation between 2018 and 2022 were included in this study. The primary outcomes were 3-month improvement in HE and postprocedural HE-related hospitalizations. HE improvement was achieved in 7 (87.5%) of 8 cases. Among all patients, there was 1 HE-related hospitalization within 90 days that responded to repeat embolization with no further admissions. No patients developed new ascites, variceal hemorrhage, or other portal hypertension complications within 3 months.
