Tandem resection of multiple spinal schwannomas

Area of Science:

• Neurosurgery
• Spinal Oncology
• Neurology

Background:

• Intradural extramedullary spinal tumors are rare and can cause significant neurological deficits.
• Surgical resection is the primary treatment modality for these tumors.
• Managing multiple tumors under a single anesthetic presents unique surgical challenges.

Purpose of the Study:

• To demonstrate the surgical technique for resecting three separate intradural extramedullary spinal tumors during a single anesthetic session.
• To highlight the use of intraoperative neuromonitoring for nerve root identification and preservation.
• To illustrate the application of laminoplasty for maintaining spinal alignment and reducing cerebrospinal fluid (CSF) leak risk.

Main Methods:

• The video depicts the surgical resection of three distinct intradural extramedullary spinal tumors.
• Intraoperative neuromonitoring, including motor evoked potentials, was employed to identify and safeguard critical motor nerve roots.
• Laminoplasty was performed at the thoracolumbar junction to ensure spinal stability and minimize postoperative CSF leakage.

Main Results:

• Successful resection of all three spinal tumors was achieved in a single procedure.
• Neuromonitoring confirmed the integrity of motor nerve roots throughout the surgery.
• Laminoplasty effectively preserved spinal alignment, with no reported postoperative CSF leak.

Conclusions:

• Simultaneous resection of multiple intradural extramedullary spinal tumors is feasible and safe.
• The integration of neuromonitoring and reconstructive techniques like laminoplasty is crucial for optimal surgical outcomes.
• This approach minimizes patient morbidity by consolidating treatment into a single anesthetic event.
