Aim: Role of color doppler in evaluation of portal hypertension. Material and methods: All the patients visiting the institution during the study period with clinical features that is suggesting towards the portal hypertension are included in the study. We had included 50 patients and 50 subjects in our study. GE Voluson S8 USG Machine, and LOGIC P9 USG Machine Siemens Acuson 300 USG Machine curvilinear array low frequency (2-5 MHz) and linear array high frequency (5- 13MHz) transducer was used. Results: The mean damping index in Class A patients was 0.56 ± 0.09, in Class B patients, it was 0.61 ± 0.05 and in Class C patients, it was 0.65 ± 0.03. The comparison of mean damping index among the Child Pugh Scores was done using One-Way ANOVA, which was found to be statistically significant (F value = 10.598, P value = 0.001), which shows that there is a significant variation in the mean damping index among the Child Pugh Scores. The mean damping index was lowest in Class A and highest in Class C. With the increase in the Child Pugh Score, the mean damping index also increases. Conclusion: Child Pugh Score when conjunct with damping index can effectively predict the prognosis patient. Color doppler successfully recognized each of these traits.
