COAGULATION DISORDERS IN LIVER DISEASE

- Pathological Basis:
- The liver is the site of synthesis of all coagulation
proteins (except von Willebrand factor), plasminogen,
and various physiologic inhibitors such as Antithrombin
III and Alpha 2-antiplasmin.
- Pathological basis of bleeding in liver disease can be
explained using the following factors:
- Decreased production of coagulation proteins.
- Decreased clearance of activated coagulation factors.
- Thrombocytopenia due to decreased production of
platelets or increased sequestration by the spleen.
- Increased fibrinolysis.
- Qualitative abnormalities of platelets.
- It is often difficult to differentiate DIC from liver
failure as the cause of coagulation disorder. Presumably,
a low degree of DIC is common in patients with liver failure.
- Treatment:
- Supportive care.
- FFP.
- Platelet transfusion if indicated.
- Vitamin K if needed.
Diagnostic Criteria:
- Liver_failure
- PT:abnormal
- APTT:abnormal
- Plt_count:abnormal(low)
- Bleeding_time:abnormal
- TT:abnormal
- FSP:abnormal
