Cerebrospinal fluid fistula secondary to dural tear in anterior cervical discectomy and fusion: case report

Abstract

Study design: A case of cerebrospinal fistula secondary to a dural tear during anterior cervical discectomy and fusion.

Objectives: To report a quite rare complication associated with anterior cervical discectomy and remind the spinal surgeons that this infrequent complication can easily become a very serious one.

Summary of background data: Anterior cervical discectomy represents one of the most commonly performed spinal procedures. Of the associated complications, accidental dural tear can lead to the development of a cerebrospinal fluid (CSF) fistula. Although this complication has been mentioned in several clinical series, the body of knowledge regarding incidence and appropriate treatment is definitely limited.

Methods: After undergoing anterior cervical discectomy and fusion for an extruded disc at the C4-C5 level, a CSF fistula developed in a 37-year-old patient as a result of a dural tear. The patient underwent a second procedure for surgical wound revision, meticulous dural opening coverage, and insertion of a lumbar drain for draining CSF for 5 days.

Results: The patient was hospitalized for 5 days and then discharged with no evidence of CSF leakage. His follow-up of 9 months revealed complete resolution of his preoperative symptomatology and no other problems associated with the complication of the CSF fistula.

Conclusion: Early identification of this complication and aggressive treatment with insertion of lumbar drain, CSF drainage for 4-5 days, and coverage of the dural tear with fibrin sealant or autologous fascia graft can prevent the development of any consequences.
