CT discography is the most effective imaging method for selecting patients for percutaneous laser disc decompression (PLDD). This study found CT discography predicted successful PLDD outcomes in 100% of cases.

Area of Science:

  • Neurosurgery
  • Radiology
  • Minimally Invasive Procedures

Background:

  • Percutaneous laser disc decompression (PLDD) effectively treats contained lumbar herniated nucleus pulposis (HNP).
  • Preoperative imaging selection is crucial for successful PLDD outcomes.
  • Not all lumbar imaging modalities equally identify suitable HNP candidates for PLDD.

Purpose of the Study:

  • To evaluate the correlation between preoperative lumbar imaging results and successful outcomes in patients undergoing PLDD.
  • To determine which imaging modality best predicts success for PLDD candidates.

Main Methods:

  • Retrospective review of 90 patients who underwent PLDD.
  • Analysis of the correlation between abnormal findings on MRI, CT, myelography, and CT discography with treatment success (MacNab criteria improvement).

Main Results:

  • Overall success rate (MacNab criteria improvement) was 73.3%.
  • Abnormal CT discogram findings correlated with PLDD success in 100% of treated patients.
  • Abnormal MRI, CT, or myelography correlated with success in 75% or fewer patients.

Conclusions:

  • CT discography is superior to MRI, CT, and myelography in identifying patients who will benefit from PLDD.
  • A diagnostic decision scheme for prospective PLDD patients is proposed based on imaging modality effectiveness.
