Spinal pseudomeningocele closure: capsulofascial interposition technique.

Area of Science:

• Neurosurgery
• Pediatric Surgery
• Plastic Surgery

Background:

• Spinal pseudomeningocele is a complication of dural repair, causing significant morbidity in pediatric patients.
• Cerebrospinal fluid (CSF) leaks lead to headaches, incisional breakdown, meningitis, and cosmetic deformity.
• Management of spinal pseudomeningocele is challenging, with varied surgical approaches.

Purpose of the Study:

• To describe a novel multidisciplinary surgical technique for symptomatic spinal pseudomeningocele repair.
• To characterize the technical aspects of capsulofascial interposition for pediatric spinal pseudomeningocele.

Main Methods:

• A combined neurosurgery-plastic surgery team performed capsulofascial interposition.
• The technique involves interposing capsulofascial tissue during dural reconstruction.
• This approach was applied to 10 pediatric patients with symptomatic spinal pseudomeningoceles.

Main Results:

• No patients required reoperation after the capsulofascial interposition procedure.
• Zero infections were reported post-pseudomeningocele closure.
• Two patients needed postoperative blood transfusions, and two underwent CSF diversion.

Conclusions:

• Capsulofascial interposition is a safe and effective technique for surgical repair of symptomatic spinal pseudomeningoceles.
• This multidisciplinary approach minimizes complications such as reoperation and infection.
• The technique represents a valuable addition to the management of pediatric spinal pseudomeningoceles.
