Primary Outcome Measures
NameTimeMethod
Improvement in covertHepatic Encephalopathy in both groups.1 year

Covert HE or overt HE will be analysed using clinical examination(west haven grading), specialised tests like stroop test, CFF(critical flicker frequency) or in rare cases EEG can be done.

Secondary Outcome Measures
NameTimeMethod
Changes in portal flow in both groups.1 year

Change will be measured by ICG and Doppler study tests.

Number of patients with adverse effects of PARTO/BRTO (Balloon-occluded retrograde transvenous obliteration) in both groups.1 year
Number of participants with Liver transplant or death in both groups.1 year
Change in MELD (Model for End Stage Liver Disease) by >5 point improvement in both groups.6 months

MELD: A disease severity scoring system for adults with liver disease, designed to improve the organ allocation in transplantation based on the severity of liver disease rather than the length of time on the waiting list.A MELD score is a number that ranges from 6 to 40, based on lab tests.

Change in ammonia level in both groups1 year
Incidence of ascites in both groups1 year

Acute variceal bleed (AVB) - will be estimated by history of hematemesis, melena, and AVB will be confirm by endoscopy if these clinical history present. It can be oesophageal variceal or gastric variceal bleed as per sarin's classification, which is confirmed and managed with endoscopy procedure. AVB is defined as a bleed in a known or suspected case of PHT, with the presence of hematemesis within 24 h of presentation, and/or ongoing melena, with last melanic stool within last 24 h. The time frame for the AVB episode is 48 h. AVB is further classified as active or inactive at the time of endoscopy. BRTO/PARTO is technically feasible, safe, and effective for gastric variceal haemorrhage in patients with portal hypertension.

Change in CTP (Child-Pugh score) by 2 points improvement in both groups.6 months

CTP- Child-Turcotte-Pugh score is ranges from 5 to 15, lowest is best and highest is worst .

Number of patients with prevention of Gastro-Variceal bleed in both groups.1 year

It is a clinical outcome and it will be assessed by history and will be confirmed and managed by endoscopic procedure.
