Summary
Contrast-enhanced MRI effectively identifies causes of Failed Back Surgery Syndrome (FBSS), guiding treatment. This imaging modality is crucial for postoperative spinal evaluation and patient management.
Area of Science:
- Radiology
- Neurosurgery
- Spinal Surgery
Background:
- Failed Back Surgery Syndrome (FBSS) encompasses diverse symptoms following spinal surgery.
- Treatment for FBSS is complex, ranging from conservative care to reoperation.
- Advanced imaging is vital for diagnosing FBSS causes and directing therapy.
Purpose of the Study:
- To assess the range of imaging findings in postoperative MRI for FBSS patients.
- To correlate MRI findings with clinical presentations in FBSS.
Main Methods:
- A cross-sectional study included 30 symptomatic FBSS patients.
- All patients underwent contrast-enhanced 1.5 Tesla MRI; NCCT was used for implant assessment.
- Exclusion criteria included MRI contraindications.
Main Results:
- MRI revealed recurrent/residual disc herniation (16), epidural scar tissue (6), and combined herniation/scar (3).
- Other findings included arachnoiditis (2), discitis (2), and implant malalignment (1).
- Eight patients required reoperation for recurrent disc herniation; one for implant malalignment.
Conclusions:
- Contrast-enhanced MRI is the preferred imaging modality for postoperative spine assessment.
- MRI accurately identifies causes of FBSS, informing appropriate treatment strategies.
