Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to evaluate the effectiveness of L-ornithine-L-aspartate (LOLA) on plasma ammonia in cirrhotic patients after Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
