Purpose
The aim of the study was to evaluate the relationship between the diameter and aneurysmal dilatation of the paraumbilical vein (PUV) and the presence of portosystemic collateral shunts and their relationship with age and portal vein diameter.

Material and methods
The retrospective analysis, performed in the II Department of Radiology, Medical University Hospital in Warsaw, included 126 patients (77 males and 49 females) with patent umbilical vein and signs of portal hypertension due to liver cirrhosis. All patients underwent contrast enhanced abdominal CT. The average age was 54.7 ±12.98. We analysed the number and type of portosystemic collateral channels in respect of age, sex, presence of oesophageal varices, and the diameter of the paraumbilical vein and the portal vein.

Results
Our results disclosed statistically significant negative correlation between patient age and diameter of paraumbilical vein, number of portosystemic collateral channels and diameter of portal vein and positive correlation between diameter of paraumbilical vein and diameter of portal vein. A statistically significant difference in diameter of portal vein and number of collateral channels was found in groups with and without oesophageal varices. No significant difference in age and portal vein diameter was found in these groups.

Conclusions
Our study showed that younger patients with liver cirrhosis are characterised by wider paraumbilical veins and higher number of portosystemic collateral channels. The presence of oesophageal varices does not correlate with age, sex, diameter of paraumbilical vein, and number of collateral portosystemic channels.
