Abstract

Percutaneous epidural balloon neuroplasty (PEBN) can be used to perform balloon decompression combined with percutaneous epidural neuroplasty (PEN), leading to significant pain relief and functional improvement in patients with lumbar spinal stenosis. Several studies have demonstrated the effectiveness of PEBN and supported its relatively long-term outcomes (at least 6 months, sustained for up to 12 months). Balloon neuroplasty appears to be superior to conventional PEN. Moreover, it has been shown to be effective in patients unresponsive to conventional PEN or in those with post lumbar surgery syndrome. In addition, balloon neuroplasty achieved successful outcomes regardless of the approach used, such as retrodiscal, transforaminal, contralateral interlaminar, or caudal. Chronic lumbar radicular pain without back pain, neurogenic claudication, and minimal neuropathic component were favorable predictors of successful PEBN from a symptomatic perspective. A short duration of pain after lumbar surgery, lumbar foraminal stenosis caused primarily by degenerative disc, mild foraminal stenosis, and perineural adhesion by degenerative discs were associated with successful outcomes of PEBN from pathological aspects. Ballooning ≥ 50% of the target sites and complete contrast dispersion after ballooning seemed to be crucial for successful outcomes from a technical perspective. In addition, PEBN was effective regardless of the accompanying redundant nerve roots or a mild degree of spondylolisthesis. Studies on balloon neuroplasty have reported occasional minor and self-limiting complications; however, no PEBN-related significant complications have been reported. Given the present evidence, balloon neuroplasty appears to be a safe and effective procedure with minimal complications for the treatment of lumbar spinal stenosis.
