Introduction: The assessment of portal vein size by ultrasonography is an important noninvasive investigation which supports the diagnosis of portal hypertension in children and adults. Indian data regarding normal portal vein diameter in children are sparse. Present study was undertaken to establish normal range of portal vein diameter in children in relation to age, weight and height. Material and methods: During September 2015 to May 2018, a prospective study of 148 patients was carried out in the department of paediatrics and radiology at L.G.Hospital, Ahmedabad between the age group of day 1 of life to 15 years, residing in Gujarat and adjacent areas of MP and Rajasthan. The measurement of portal vein diameter at porta made during quiet breathing in younger children and during breath-holding in older children. Neither preparation nor sedation was used. Results: Portal vein diameter highly correlated with each of the variables: age, height, weight. The correlation observed was all similar in magnitude and highly significant (P < 0.0001). Most statistically significant correlation with portal vein diameter was observed with height. The mean portal vein diameter increased with height. Conclusion: Most statistically significant correlation with portal vein diameter was observed with height. The mean portal vein diameter increased with height.
