Abstract               Background: Diameter of the portal vein at porta hepatis is measured on ultrasound to diagnosed portal hypertension. Method: 103 (51 male and 52 females)normal adults were included in the study group. Portal vein diameter was measured by the ultrasound at porta hepatis by expert. Various parameters such as Age, height, weight and body surface were noted and compared with diameter of portal vein to find the correlation. Significant correlation was identified with age, weight and body surface area. Results: Mean diameter of portal vein was observed 9.20 mm. Positive correlation were identified with the parameters such as height, and body surface area. Conclusion: To identify Portal vein diameter at porta hepatis by ultrasound is important and valuable finding in diagnosing the portal hypertension, Height and body surface area have to be considered while measuring the diameter of portal vein.
