Abstract
Purpose
To evaluate the technical efficacy, safety, and reproducibility of automated percutaneous lumbar discectomy (APLD) under CT and fluoroscopic guidance, for treating radiculopathy caused by lumbar disc herniation in patients impervious to conservative treatment.
Methods
A total of 77 patients with symptomatic lumbar disc herniation were treated with APLD in a prospective multicentric study performed in four centers across three countries. Magnetic resonance imaging and/or computed tomography was used to evaluate the disc herniation before and after the procedure. Only local anesthesia was used during these procedures. Clinical outcomes were measured with the visual analog scale (VAS) for pain at one and 6 months after the procedure.
Results
Technical success rate was 100% with a mean intervention duration of 30 min (15–45 min). No complications occurred during the procedure. Post-lumbar puncture syndrome occurred in three patients who were successfully treated with blood patches. VAS decreased from a mean of 8 before the intervention to 3 1 month after (p value = 0.001). The requirement for analgesia decreased from 100 to 27%. No statistically significant differences in outcomes were found between the centers.
Conclusion
APLD with dual imaging guidance under local anesthesia is a safe, feasible, and reproducible technique to treat symptomatic lumbar disc herniation.
