The role of radiology in percutaneous laser disc decompression

Diagnostic imaging has always played a key role in the evaluation of patients with suspected lumbar disc herniation. With the development of percutaneous laser disc decompression (PLDD), radiology is now equally important in its treatment. All physicians involved with the PLDD candidate must be familiar with the imaging techniques unique to this procedure to ensure a successful outcome. The following review is based on the cumulative experience gained in performing over 200 PLDD procedures. It discusses the function of diagnostic radiology in all facets of PLDD including patient selection, intraoperative imaging, postoperative evaluation, and analysis of complications. Fundamental radiologic concepts that apply to PLDD are explained and protocols suggested to optimize results and avoid complications.
