Inadvertent glue injection during spinal arteriovenous fistula treatment caused acute medullary syndrome. Magnetic resonance (MR) imaging revealed spinal cord infarct in the posterior spinal artery territory, demonstrating MR imaging

Area of Science:

  • Neurology
  • Vascular Surgery
  • Radiology

Background:

  • Spinal dural arteriovenous fistulas are treated via endovascular occlusion.
  • Accidental injection of embolic material into spinal arteries can cause ischemia.

Observation:

  • A patient developed acute medullary syndrome after inadvertent glue injection into the right posterior radiculomedullary artery during T-11 spinal dural arteriovenous fistula treatment.
  • Magnetic resonance (MR) imaging performed 40 days post-procedure showed signal alterations and contrast enhancement in the T10-T11 posterior and right lateral columns.
  • Follow-up MR imaging at 4 months revealed persistent, non-enhancing signal changes in the same spinal cord regions.

Findings:

  • The observed MR imaging findings were consistent with an infarct in the posterior spinal artery territory.

Related Experiment Videos

  • This case highlights the utility of MR imaging in detecting and monitoring spinal cord infarcts secondary to endovascular procedure complications.

    • Implications:

    • This case underscores the potential risks of inadvertent embolization during spinal vascular interventions.
    • It emphasizes the importance of meticulous technique and advanced imaging for diagnosing and managing complications.
    • Understanding the imaging characteristics of spinal cord infarcts is crucial for effective patient management.
