This report details two rare cases of paraumbilical vein aneurysm in patients with liver cirrhosis and portal hypertension. Imaging revealed localized, focal aneurysmal dilatation of the paraumbilical vein, a seldom-seen condition.

Area of Science:

  • Vascular Surgery
  • Hepatology
  • Diagnostic Imaging

Background:

  • Liver cirrhosis frequently leads to portal hypertension.
  • Portal hypertension can cause venous system abnormalities.
  • Paraumbilical vein dilation is a known complication of portal hypertension.

Observation:

  • Two patients with cirrhotic liver and portal hypertension presented with paraumbilical vein abnormalities.
  • Angiography and contrast-enhanced computed tomography (CT) were utilized for diagnosis.
  • Imaging confirmed a dilated paraumbilical vein originating from the left portal vein branch.

Findings:

  • The primary finding was a focal aneurysmal dilatation of the paraumbilical vein.
  • This localized aneurysmal dilatation represents a rare manifestation of paraumbilical vein pathology.

  • The condition was observed in the context of significant liver disease.

    • Implications:

    • Highlights the importance of considering rare vascular complications in cirrhotic patients.
    • Suggests advanced imaging techniques are crucial for diagnosing such anomalies.
    • Contributes to the limited literature on paraumbilical vein aneurysms, aiding future research and clinical recognition.
