Primary Outcome Measures:
  • Plasma ammonia [ Time Frame: One week ]
    The plasma ammonia concentrations of venous blood at the first, fourth and seventh days after TIPS procedure.


Secondary Outcome Measures:
  • Incidence of hepatic encephalopathy [ Time Frame: One week ]
  • Liver function [ Time Frame: One week ]
    The liver function (includes PT/INR, APTT, albumin, bilirubin, Child-Pugh score) at the first, fourth and seventh days after TIPS procedure.

  • Psychometric tests [ Time Frame: One week ]
    The results of the psychometric tests (include number connection test A, number connection test B, digit symbol test, serial dotting test, line tracing test) at the first, fourth and seventh days after TIPS procedure.


Enrollment: 40
Study Start Date: December 2011
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: LOLA group
Intervention: LOLA (30g per day) for a week.
Drug: L-ornithine-L-aspartate
The patients will be treated with LOLA (30g per day) for a week after TIPS procedure.
No Intervention: Control group
Patients will not be treated with LOLA.

Detailed Description:
Patients with successful TIPS deployment are randomized to LOLA arm and blank control arm. Plasma ammonia concentrations are measured before TIPS, day 1, day 4 and day 7 after TIPS.
