Autologous fibrin glue for endoscopic skull base repair in patients with cerebrospinal fluid leakage.

UNLABELLED

The main stages of endoscopic skull base repair in patients with cerebrospinal fluid (CSF) leakage are identification of bone boundaries of the fistula and its closure by auto- and allografts. Fibrin glue can be used to fix plastic materials and additionally seal skull base defect.

OBJECTIVE

To analyze efficacy and safety of Vivostat autologous fibrin glue for endoscopic skull base repair in patients with nasal CSF leakage and to compare postoperative outcomes after defect closure by Vivostat fibrin glue and allogeneic fibrin glue.

MATERIAL AND METHODS

A retro- and prospective analysis included 56 patients with nasal CSF leakage who were treated at the Burdenko Neurosurgery Center between January 2021 and June 2022. Patients were divided into 2 groups: Vivostat fibrin glue (=27, 48.2%) and allogeneic fibrin glue (=29, 51.8%). Demographic and clinical perioperative data were analyzed.

RESULTS

No early postoperative recurrence of CSF leakage was registered in both groups, whereas meningitis occurred in 2 cases in each group. Recurrent CSF leakage in delayed postoperative period occurred in 1 patient (3.4%) of the control group (>0.05). Incidence of perioperative complications, subfebrile temperature in early postoperative period, surgery time and hospital-stay were similar.

CONCLUSION

Vivostat autologous fibrin glue is a safe and effective method for fixing the grafts in endoscopic skull base repair. The advantages of this approach are easy application, elimination of the risk of allergic, immunological and infectious complications, as well as acceleration of tissue regeneration.
