Background: The hepatic portal vein, a short, wide vein, is formed by
the superior mesenteric and splenic veins posterior to the neck of the

(Khartoum state), ultrasound was done investigating portal vein diameter .
Results: The results showed that the patients at the age of sixty years old,

underwent abdominal ultrasound for various reasons. When comparing the
study between men and women it was found that most abnormal variations
are in men. Also it was found that the average diameter of portal vein 12.

ranging below 12 mm with a normal respirophasic variation (above the
cutoff point for portal hypertension).
