Determination of mean portal vein diameter: An approach with Computed Tomography

Okan Dilek, Omer Kaya

Abstract


Purpose: The aim of study is to determine the range of values and upper limit of mean portal vein diameter (MPVD) in healthy individuals and to investigate the effect of gender, age, height, liver and spleen size, as well as body mass index (BMI) on these values.

Material and Methods: In this retrospective study, the MPVD of the individuals with BMI between 18.5-24.9, without cardiac or liver disease, were evaluated by consensus of two radiologists on contrast-enhanced CT images. A total of 180 individuals, 15 men and 15 women from each decade between the ages of 20-80, were included. The correlation between the parameters was evaluated with Spearman’s correlation test. p<0.05 values were considered statistically significant.

Results: MPVD was 12.75 ± 1.20 mm (SD), and mean BMI of the participants was 22.2 kg/m2. There was a positive correlation between MPVD and height and BMI (BMI; CI, 0.517-0.752, Height; CI, 0.536-0.719). In comparison by gender, MPVD was found to be significantly wider in males than in females.

Conclusions: The results of our study indicate that acceptable value for the upper limit of MPVD is 13 mm, but the upper limit should be assessed according to body measurements such as BMI, height and gender in order to evaluate patients for portal hypertension.
