Liver biopsy in liver patients with coagulopathy
2008
: The risk of severe bleeding after liver biopsy is estimated to be 1:12,000 in patients with near normal coagulation (INR 60 billion /l). Beyond these limits, the risk is higher, but still uncertain. The Danish guidelines require INR > 1.5, platelet count < 40 billion /l and normal APTT. In some instances the risk of not knowing the histology is so high that a biopsy is considered even with a more disturbed coagulation. Vitamin K, freshly frozen plasma and recombinant activated factor VII may reduce the risk of bleeding in specific situations, but no firm recommendations can be given.
