NCT04216992

Brief Summary

Conventional epidurography (CE) is thought to have insufficient usefulness on percutaneous epidural adhesiolysis (PEA). The investigators aimed to evaluate the association between the outcome of PEA and three dimensional-rotational epidurography (3D-RE). The investigators performed 30 PEA in 26 patients, and evaluated their post-PEA image findings. Two independent clinicians categorized and recorded the occurrence of contrast at intra-canal ventral and extra-foraminal regions on CE; and contrast at dorsal canal (DC), ventral canal (VC), dorsal foramen (DF), and ventral foramen (VF) on 3D-RE. Reproducibility was assessed using intra-class correlation coefficients (ICCs). The symptom relief after one month for the patients receiving PEA and the contrast distribution patterns of CE and 3D-RE and were determined.

Outcome Measures

Primary Outcomes (3)

  • Symptoms change after PEA

    For the comparison of clinical outcomes according to the symptoms change, the participants' symptoms change was rated using a Likert scale to defined two groups by exhibiting \>= 50% symptoms change and \< 50% symptoms change.

    1 month

  • Reproducibility of CE and 3D-RE

    Inter-reader agreement was evaluated using the intra-class correlation coefficients (ICCs), calculated according to Landis and Koch, for the contrast distribution of CE and 3D-RE.

    1 month

  • Usefulness of 3D-RE for predicting the outcome of PEA

    Simple linear regression analysis was used to determine the prediction of the outcome of PEA by the contrast distribution of CE and 3D-RE.

    3 months

Secondary Outcomes (1)

  • Radiation exposure of PEA

    1 month

Study Arms (1)

Three dimensional-rotational epidurography (3D-RE)

3D-RE is obtained on a commercial digital bi-plane angiography system. Reconstruction time was 30 seconds. Detailed information regarding technical performance and reconstruction procedure has been reported. Postprocessing techniques provided by the software included real-time 3D volume rendering and multiplanar reformatting. Real-time 3D volume rendering creates a 3D model of the examined object. The software allows emphasizing bony structures or soft tissue by changing intensity, brightness, and opacity of different X-ray structures. Additionally, rotation of the 3D object in all directions is possible, as is a virtual stereoscopic view provided by the software in combination with special glasses. The multiplanar reformatting modus generates virtual sections according to the three main axes and free defined axes. The section planes can be freely chosen, and curved sectioning is also possible.

Device: Cone beam computed tomography

Interventions

The contrast agent (Omnipaque, GE Healthcare, Ireland) was instilled to confirm the epidural space. With use of a calibrated angiographic C-arm system and a postprocessing workstation, we acquired volume data sets from two dimensional digital projection images obtained to reconstruct the 3D-RE during a C-arm rotation around the patient axis.

Eligibility Criteria

AgeUp to 20 Years
Sexall
Age GroupsChild (0-17), Adult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Patients who had FBSS or SS with unilateral radiculopathy underwent PEA.

You may qualify if:

  • FBSS or SS with unilateral radiculopathy.
  • History of discogenic or radicular symptoms refractory to conservative treatments and epidural steroid injection for a minimum of 6 weeks.
  • The PEA was standardized to all patients receiving the procedure.
  • Each patient received an epidural injection, and if the symptoms persisted or the relief was insufficient, the patient received PEA \>6-week interval between the epidural steroid injection.
  • Positive provocative test during PEA was used to confirm the affected spinal level.
  • All patients underwent CE before and after PEA; and 3D-RE after PEA.

You may not qualify if:

  • History of spinal surgery and those with cauda equina syndrome
  • Bleeding diathesis
  • Associated somatic or psychiatric disease
  • Vertebral fractures
  • Pregnancy
  • Tumors
  • Other underlying systemic diseases that could significantly influence the procedural outcomes were excluded.
  • Bilateral symptoms
  • Did not react to the provocation during PEA
