Tissufleece® (Baxter; Unterschleißheim, Germany) is a natural equine collagen and is an appropriate hematostatic material for covering the bleeding surface. It consists of heterologous collagen fibrils acquired from devitalized connective tissue and is fully reabsorbable. Tissucol Duo® is a typical two component adhesive. The first part includes human plasma proteins (fibrinogen, factor XIII, plasma fibronectin, and the plasmin inhibitor aprotinin). The second part includes thrombin and CaCl2. Prior to application of Tissucol Duo®, injectors were kept for 20–30 min at room temperature for melting. The “treatment surface” was covered with a combination of the two injector contents and the TissuFleece® boards were attached and left for 2 min. Two TissuFleece® plates and 4 ml Tissucol Duo® were applied to seal the hepatic resection field.
