Summary
Liver transplantation can activate coagulation and fibrinolysis, even in low-risk patients. Management post-revacularization should address consumptive coagulopathy and fibrinolysis with antithrombin and antifibrinolytic agents.
Area of Science:
- Hepatology
- Transplantation Surgery
- Hematology
Background:
- Liver transplantation involves complex physiological changes.
- Coagulation and fibrinolysis are critical aspects of perioperative management.
Purpose of the Study:
- To investigate coagulation and fibrinolysis activation during liver transplantation.
- To identify optimal therapeutic strategies for managing bleeding complications.
Main Methods:
- Study included 14 selected liver transplant patients.
- Coagulation parameters were monitored throughout the procedure.
- Blood usage was limited to 8.5 liters per patient.
Main Results:
- Preoperative coagulation was minimally deranged in selected patients.
- Coagulation and fibrinolysis activation occurred during the anhepatic phase and after hepatic revascularization.
- Bleeding was manageable in all cases with limited blood usage.
Conclusions:
- Even in low-risk liver transplant recipients, significant activation of coagulation and fibrinolysis is observed.
- Post-revacularization bleeding management should include addressing consumptive coagulopathy and fibrinolysis.
- Antithrombin supplementation and antifibrinolytic agents (e.g., aprotinin) are suggested adjuncts to therapy.
