Safety biocompatibility of gelatin hemostatic matrix (Floseal and Surgiflo) in neurosurgical procedures.

Adequate hemostasis in cranial and spinal surgery is of paramount importance in a neurosurgeon's daily practice. Generalized ooze bleeding from the surgical wall cavities, coming from the dura mater or nervous tissue may be troublesome and may limit visualization in minimally invasive neurosurgery. Hemostatic matrix is a mixture of a flowable gelatin matrix (bovine or porcine) and a thrombin component mixed together. A total of 318 patients undergoing cranial, craniospinal, and spinal procedure with the use of gelatin hemostatic matrix (Floseal and Surgiflo) were enrolled in this clinical study. We compared the different hemostatic techniques using the gelatin hemostatic matrix, and investigated indications, time to bleeding control, and its efficacy and safety in neurosurgery.
