Lumbar–Peritoneal Shunt as A Therapeutic AlternativeAfter A Failed Skull Base Defect Repair in A Pediatric Post-Traumatic CSF Leak: A Case ReportAnd Literature Review

Introduction: Cerebrospinal fluid (CSF) leakage secondary to cranial trauma is a rare but serious complication. Surgical repair of the skull base remains the treatment of choice. In cases of surgical failure, placement of a lumbar–peritoneal shunt (LPS) may represent an effective alternative [1], [5], [8], [10] Case Report: We report the case of a 10-year-old girl who sustained cranial trauma resulting in a skull base fracture and persistent CSF leakage despite initial surgical repair. Placement of a lumbar–peritoneal shunt resulted in complete resolution of the leak without complications. Discussion: The LPS reduces CSF pressure, thereby facilitating spontaneous closure of the dural defect. This technique is less invasive than repeat surgery and can be used when the initial repair fails [4–15]. Conclusion: Lumbar–peritoneal shunting is a safe and effective therapeutic option for persistent post-traumatic CSF leaks following failed skull base repair.
