Overview
Laboratory findings is usually normal among patients with portal vein thrombosis. In patients with cirrhosis, laboratory findings may demonstrate an elevated bilirubin, low platelet count, prolonged international normalized ratio (INR), or renal insufficiency.
Laboratory Findings
- Laboratory findings of portal vein thrombosis will be normal or quite normal, unless there is coexistence of a liver disease.
- Although, coagulation factors levels could be moderately decreased, while D-dimer level is usually increased.
- In some patients laboratory findings may show moderate increase in serum aminotransferases.[1][2][3]
- In patients with cirrhosis, laboratory findings may demonstrate an elevated bilirubin, low platelet count, prolonged international normalized ratio (INR), or renal insufficiency.
- Blood cultures of septic portal vein are often positive for Bacteroides fragilis or Escherichia coli, also other pathogens have been cultured.[4]
