Long-term results and predictors of postoperative outcomes in patients with cauda equina syndrome following degenerative lumbar spine disease.

UNLABELLED: Cauda equina syndrome (CES) associated with acute disc extrusion or spinal stenosis often requires emergency surgery. Analysis of the Pubmed, Medline and eLibrary databases revealed a few studies devoted to long-term postoperative outcomes in patients with CES caused by degenerative spine disease.

OBJECTIVE

To evaluate long-term postoperative results and predictors of clinical and neurological outcomes in patients with CES caused by degenerative lumbar spine disease.

MATERIAL AND METHODS. D: Ecompressive and decompressive-stabilizing procedures were performed in 211 patients with CES caused by degenerative lumbar spine disease between 2000 and 2020. Long-term clinical parameters were available in 174 patients with mean follow-up period of 7 years. Sixty-eight patients had unsatisfactory postoperative outcomes. We assessed postoperative clinical and neurological outcomes in patients with CES and predictors of these outcomes.

RESULTS

We identified the following predictors of clinical and neurological outcomes using binary logistic regression model: period between clinical manifestation and surgery >48 hours, preoperative neurological impairment, spinal canal diameter, surgical procedure, dimension of herniated disc, ASA score and long-term postoperative analgesia with narcotic analgesics.

CONCLUSION

Preoperative planning and possible correction of the above-mentioned risk factors will potentially improve postoperative outcomes in patients with CES caused by degenerative lumbar spine disease.
