Early Treatment of Cerebrospinal Fluid Leakage After Traumatic Injury Using Pedicled Autologous Fascia Flap.

Objective: This study aims to investigate the efficacy of early intervention in cerebrospinal fluid leakage following traumatic brain injury through the utilization of pedicled autologous fascia flaps.

Methods: A retrospective case series, spanning from May 2021 to May 2022, analyzed 8 traumatic brain injury cases with concomitant cerebrospinal fluid leakage. Each patient underwent simultaneous brain surgery and transcranial repair of the cerebrospinal fluid leak, employing a pedicled autologous fascia flap. Clinical and imaging data were comprehensively recorded throughout the entire duration of the cases, and patient follow-ups were conducted through outpatient visits and telephone consultations.

Results: The study comprised 8 enrolled patients, consisting of 7 males and 1 female, all of whom sustained injuries from traffic accidents. The mean age ranged from 17 to 55 years. Among the patients, three presented with acute epidural hematoma, three with simple concave fractures, and 2 with concave fractures accompanied by brain contusion. Frontal sinus fractures were observed in all cases. All surgical interventions were successful, with no instances of cerebrospinal fluid leakage postoperatively. In addition, none of the patients developed intracranial infections. At the conclusion of the follow-up period, recurrent cerebrospinal fluid leakage was not observed in any of the patients.

Conclusions: In cases where surgical intervention is necessary for cerebrospinal fluid leakage resulting from anterior cranial base fractures, the application of pedicled autologous fascia flaps in the acute stage proves effective in repairing leaks at the anterior cranial base. This approach may contribute to a reduction in the incidence of intracranial infections, ultimately yielding satisfactory patient recovery.
