Summary
Platelet transfusions may worsen bleeding in cirrhotic patients with liver cancer by increasing fibrinolysis. Cryotherapy for liver cancer can activate coagulation, as seen on thrombelastography.
Area of Science:
- Hepatology
- Oncology
- Hematology
Background:
- Cirrhotic patients with hepatocellular carcinoma often have thrombocytopenia and bleeding risks.
- Cryotherapy is a treatment option for hepatocellular carcinoma, but its impact on hemostasis is not fully understood.
Observation:
- A patient with liver cirrhosis and recurrent hepatocellular carcinoma experienced transient hyperfibrinolysis after platelet transfusion during cryotherapy.
- Thrombelastography revealed activation of coagulation following the freezing and thawing of the tumor during cryotherapy.
Findings:
- Platelet transfusion in cirrhotic patients may paradoxically increase fibrinolysis, potentially impairing hemostatic function.
- Cryotherapy for hepatocellular carcinoma can lead to perioperative activation of coagulation.
Implications:
- Clinicians should be aware of the potential pro-fibrinolytic effect of platelet transfusions in cirrhotic patients.
- Understanding the coagulation changes during cryotherapy may inform perioperative management strategies for hepatocellular carcinoma patients.
