Measurement of Portal Vein Diameter in Sudanese Using Computed Tomography

Abstract

Measurement study was done to find out the mean portal vein in Sudanese population by using computed tomography. Fifty Sudanese patient performed for abdominal CT scan in Khartoum state aged between 40 - 50 years, 25female and 25male, with CT machine –simians’ 16 slice. Portal vein was measured after injection of contrast media. The results of the study revealed that the mean diameter of main portal vein was [1.32 ±0.24] cm. The minimum diameter [0.92 cm], and maximum diameter [1.88 cm], Furthermore there was no correlation between main portal vein diameter and age, as age increased the portal vein diameter increased. The mean portal vein diameter for male [1.38±0.24] cm, is slightly higher than mean diameter for female [1.27 ± 0.22] cm. The liver length and width are increased as age increased; there was strong relation between liver size and portal vein diameter. The study conclude normal mean portal vein diameter measured on CT was significantly (mean 1.32 cm). Sex, age and size of liver affected main portal vein diameter. The study recommended using large group of ages, done study in ab abnormal patient and compare result with ultrasound.
