Summary

Liver resection is the treatment of choice in patients with primary or metastatic liver neoplasms, benign liver neoplasms and numerous biliary diseases. In these patients, in the postoperative period,several factors can induce a transient alteration of the synthesis hepatic coagulation factors such as size of the lesion liver, underlying liver disease (e.g. malignancy), pre-existing cirrhosis, duration of both surgery and vascular clamping, and blood loss. So far, some studies have shown that conventional coagulation tests indicate a hypocoagulable state which may lead to excessive transfusions of blood products or an increased risk of thromboembolic events related to delayed initiation of thromboprophylaxis in the postoperative period. In an attempt to optimizing the state of coagulation, recently there is increased interest for viscoelastic coagulation testing (thromboelastography and rotational thromboelastometry). The results of these studies have shown that these patients often have a hypercoagulable and non hypocoagulable profile as evidenced by conventional coagulation tests.

the purpose of the study is to evaluate whether the combination of coagulation tests conventional systems and new thromboelastography can increase the quality of surveillance of the coagulation state after liver surgery, in order to optimize the management of postoperative blood coagulation of these patients.

Conditions

  • Coagulation Disorder

Interventions

DIAGNOSTIC_TEST

thromboelastography (TEG®6s)

blood samples for conventional coagulation test were obtained in vacutainer tubes from an arterial line. Two blood citrate samples (3 ml, sodium citrate solution, Vacuette® Blood Tubes) were also collected for the laboratory conventional coagulation tests (aPTT, INR, D-dimer levels, Antithrombin III) and TEG®6s assessment. The TEG parameters include reaction time (R), clot formation time (K), angle or α (K angle), maximum amplitude (MA), and amplitude at 30 minutes (LY30)
