Influence of Shunt Occlusion on Organ Functions in Hyperammonemic Patients With Cirrhosis Having Porto-systemic Shunt.

The spontaneous Porto-systemic shunt is occluded by intervention procedures like Balloon Occluded Retrograde Transvenous Obliteration (BRTO), Plug-assisted Retrograde Transvenous Obliteration (PARTO) and shunt occlusion procedures resulting in diversion of blood flow towards the portal circulation and in turn the liver. According to this investigator hypothesized that shunt occlusion improves liver volume and function along with beneficial effect on other organ systems by decreasing ammonia and improving hepatopetal flow. All patients with cirrhosis having large shunt(\>10mm) and raised ammonia levels and will be randomized to receive standard medical treatment and those receiving shunt occlusion procedures. Investigator will assess organ functions and liver regenerative potential pre and post (after 3 to 15 months) procedure.
