Fibrin glue, a biologic adhesive, is made with highly concentrated human fibrinogen and clotting factors. It has become used frequently in neurosurgical procedures, in particular in the closure of the dura mata to prevent cerebrospinal fluid leakage. This report evaluates sealing effects of the fibrin glue on cerebrospinal fluid leakage through the dura. (1) Three manipulations for application of fibrin glue were used; i.e., layer, mixture and spray methods. ⋯ The fibrin plug tolerated water pressure over 200cmH2O, in every size of pore. In conclusion, the optimal method for using fibrin glue on the surface of the dura was a spray method. Fibrin plate/clot made by the spray method sealed the dural tear or pore so well that it sustained a water pressure of over 80cmH2O, which is far higher than normal pressure of the intracranial cerebrospinal fluid.
