From the Research
Complications of cervical percutaneous laser disc decompression (PLDD) are relatively low, with the most recent and highest quality study showing no complications in 14 cases, and the overall complication rate is relatively low compared to open surgical procedures. The potential complications of cervical PLDD include:
- Infection at the needle insertion site
- Bleeding
- Nerve root damage
- Discitis
- Temporary increased pain, numbness, or weakness following the procedure
- Spinal cord injury, dural puncture leading to cerebrospinal fluid leak, and thermal damage to surrounding tissues, although these are rare 1
- Procedural failure where symptoms don't improve or worsen, potentially requiring additional interventions
- Post-procedure disc herniation
- Allergic reactions to local anesthetics or contrast agents used during the procedure Most complications are temporary and resolve with appropriate management, including antibiotics for infections, analgesics for pain, and physical therapy for weakness. The overall complication rate for cervical PLDD is relatively low, which is why it's considered a minimally invasive alternative for treating cervical disc herniations, as shown in a study with 14 cases where no complications were reported 1. Proper patient selection, experienced operators, and careful technique significantly reduce the risk of these complications, and the use of ultrasound guidance with fluoroscopic validation can also minimize the risk of complications 1. It's essential to note that the risk of complications can be minimized with proper training and experience, as emphasized in a study that highlighted the importance of adequate training under close supervision of surgeons experienced in this procedure and in interventional US 1.
