Abstract: 

Background: Color Doppler ultrasound revealed to be one the most important diagnostic modalities, however, diagnosing portal venous disorders requires comparative normal values for portal diameter, peak blood velocity and volume flow.
Materials and methods: Forty-three normal adults referring to our sonography center entered this cross sectional study. They were fasted for at least 8 hours. Sonography was achieved on supine position using Gary scale B-mode and also color and pulsed wave Doppler ultrasonography. Having measured the main portal vein and its branches diameter and peak velocity, the volume flow was estimated, then, their association was determined by gender, sex, height, weight, body surface area, and body mass index.
Results: In the main portal vein, the mean (±SD) diameter, peal velocity, and volume flow were 9.57±1.89mm, 17.59±3.57, and 583±179 ml/min, respectively. The main portal vein and its braches diameter were significantly differed among males and females (P<0.01). Meanwhile, there was a significant association between the main portal vein diameter and height (P<0.05), and weight (P<0.01), however, this correlation was absent for body surface height (P<0.05), and weight (P<0.01), however, this correlation was absent for body surface and body mass index, and age. Moreover, we could not find any significant correlation between the right and left portal vein branches diameter and peak velocity and these independent variables, however a significant relation was revealed between the main portal vein and its branches diameter and peal velocity (P<0.05).
Conclusion: To compare the main portal vein diameter between healthy subjects and patients, sex difference should be taken into account. Meanwhile, volume flow of main portal vein is highly correlated with body surface area.
