Area of Science:

  • Neurosurgery
  • Pain Management
  • Radiology

Background:

  • Cordotomy techniques have advanced significantly since their inception.
  • Percutaneous radiofrequency cordotomy is now a key minimally invasive option.

Purpose of the Study:

  • To provide a comprehensive overview of CT-guided percutaneous radiofrequency cordotomy.
  • To detail the procedure for managing intractable somatic pain in malignancy.

Main Methods:

  • Review of spinal cord anatomy at C1-2.
  • Discussion of patient selection criteria.
  • Explanation of procedural setup and technique using CT guidance and intraoperative stimulation monitoring.

Main Results:

  • Highlights the evolution and current application of cordotomy.
  • Emphasizes the role of CT guidance and intraoperative monitoring in patient safety.

Conclusions:

  • CT-guided percutaneous radiofrequency cordotomy is a valuable palliative tool for specific cancer pain patients.
  • Careful patient selection and advanced techniques optimize outcomes and minimize adverse events.
