Sonographic correlation of portal vein diameter with gender in population of Lahore.

Abstract

Objective: To determine the reference values of normal portal vein diameter in correlation to gender in population of Lahore. Study Design: Cross Sectional study. Setting: Ultrasound Lab University of Lahore and Gondal Complex Lahore. Period: 5th October 2020 to 13th April 2021. Material & Methods: Sample size of my study were 164 males and 143 females. Simple random sampling was conducted. Healthy Individual with normal body mass index, both (male and female) individuals in fasting state and age between (20-25) years. Individual with history of portal hypertension, Fatty liver, Hepatomegaly and any other hepatic disorder. Xario XG. Convex 3.5 MHz-7.5MHz. Results: The mean diameter of portal vein for male was calculated as 10.51 + 1.468 mm (ranging from 13mm to 15mm), and for females was 10.085 ±1.336 mm (ranging from 7 to 14mm). Independent t-test was applied to examine the difference of mean Portal vein in males and females. We found a statistical significant difference in two means of portal vein diameter as the p-value = 0.008 is less than α =0.05. Conclusion: In this study, portal vein diameter in adult men and women were found within the normal range among age limit 20-25years.But the diameter of portal vein showed direct relation with weight and Body Mass Index among females but in males none of the body factors had any impact on the diameter of portal vein.

The Effect of Smoking, Gender, Age, and the Body Mass Index on the Measurements of the Portal Vein Diameter

“…This study revealed a strong, statistically significant correlation between BMI and the PV diameter ( P = .022; Table 5), which is consistent with the findings of the studies by Chand and Jaradi 10 and Luntsi et al, 12 which revealed a positive correlation between BMI and the PV diameter. 1 Aqeel et al 11 concluded that BMI is statistically correlated with the PV diameter in female participants.…”

“…This finding is in contrast with those of the studies by Akanni et al, 2 Geleto et al, 4 and Rapaccini et al, 15 which showed a statistically significant association between sex and the PV diameter. Aqeel et al 11 proposed that the association was only present between female sex and PV diameter.…”

“…Chand and Jaradi 10 reported that the PV diameter shows significant correlations with age, height, and weight in children. Aqeel et al 11 reported that the PV diameter shows direct correlations with weight and body mass index (BMI) in female participants; however, none of the body factors showed any correlations with the PV diameter in the male participants.…”

Gender Differences in Pharmacokinetics: A Perspective on Contrast Agents

“…Lower plasma concentrations generally lead to a lower signalto-noise ratio. The smaller vessel size in women 24 and the higher needle/vein size ratio may also contribute to a higher risk of extravasation in women. Furthermore, the lower blood volume in women 25 will likely increase plasma contrast agent levels.…”
