Summary

A new technique, intraoperative endomyelography, confirms syrinx cavity continuity before surgical drainage. This method prevents drainage failure due to septations, improving surgical outcomes for patients with spinal cord syrinxes.

Area of Science:

  • Neurosurgery
  • Diagnostic Imaging
  • Spinal Cord Disorders

Background:

  • Surgical drainage is a common treatment for spinal cord syrinxes.
  • Accurate assessment of syrinx cavity continuity is crucial for successful surgical drainage.
  • Existing noninvasive techniques lack certainty in evaluating septated syrinxes.

Observation:

  • A novel technique, intraoperative endomyelography, is presented for pre-surgical evaluation.
  • This method involves injecting a contrast agent to visualize the syrinx cavity.
  • Pressure measurements can be taken before contrast injection.

Findings:

  • Intraoperative endomyelography reliably confirms the continuity of a septated syrinx cavity.
  • The technique is simple, requires no specialized equipment, and can be performed intraoperatively.

  • Pre-injection pressure measurements offer insights into syrinx pathogenesis.

    • Implications:

    • This technique can prevent surgical drainage failure caused by undetected septations or double cavities.
    • It enhances the predictability and success rate of syrinx surgeries.
    • Pressure data may guide prognosis and therapeutic strategies for syringomyelia.
