The Effect of Additional Transforaminal Epidural Blocks in Percutaneous Epidural Neuroplasty
The Effect of Additional Transforaminal Epidural Blocks in Percutaneous Epidural Neuroplasty
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.
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.
