The Effect of Additional Transforaminal Epidural Blocks in Percutaneous Epidural Neuroplasty

• Conditions: Lumbar Spinal Stenosis
• Interventions: Procedure: Transforaminal Block

• Registration Number: NCT03867630
• Lead Sponsor: Ajou University School of Medicine

Brief Summary

Percutaneous epidural neuroplasty (PEN) is an effective interventional treatment for radicular pain. But in some cases with wire catheter like Racz catheter, contrast runoffs were not shown to the foramen. This study will show that contrast runoff will affect the results of PEN and in cases which contrast runoff are not shown, additional transforaminal epidural blocks will affect the results of PEN by reviewing medical record, retrospectively.

Detailed Description

Medical records will be investigated in cases of PEN with wire type catheter from May 2016 to August 2018. About one hundred cases will be enrolled. Analysis will be performed. It will be compared 1) Success rate of Runoff group and Nonrunoff group in lumbar spine, 2) Success rate of Runoff group and Nonrunoff-NonTransforaminal group in lumbar spine. 3) Success rate of Runoff group with nonrunoff-transforaminal group and Nonrunoff-NonTransforaminal group in lumbar spine. 4) Success rate of Nonrunoff-Transforaminal group and Nonrunoff-NonTransforaminal group in lumbar spine.

Arm && Interventions

Group	Intervention	Description
Nonrunoff-Transforaminal group	Transforaminal Block	Nonrunoff-Transforaminal group are the patients whose images are not shown root shadows by contrast media, so additional transforaminal blocks are done.

Primary Outcome Measures

Name	Time	Method
Success rate of three groups	1 month	Success rate of three groups(Runoff group, Nonrunoff-foraminal group, Nonrunoff-Nonforaminal group) will be compared each other. Success is defined as a 50% or greater reduction in pain score on the pre-procedural Visual Analogue Scale(VAS) score.
