What is PLDD Neurosurgery Laser Spine Surgery treatment?
Background and objective: Percutaneous laser disc decompression (PLDD) is a procedure in which herniated intervertebral discs are treated by reduction of intradiscal pressure through laser energy. This is introduced by a needle inserted into the nucleus pulposus under local anesthesia and fluoroscopic monitoring.
The laser is based on the transformation of light energy into thermal, its advantages are given by having a minimal penetration in tissues, limited heat diffusion, allows the cutting, vaporization and coagulation of small vessels as well as minimal damage to adjacent parenchyma. In some cases it can be performed via Neuroendoscope.
The Principle of PLDD
In the procedure of percutaneous laser disc decompression, laser energy is transmitted through a thin optical fiber into the disc. The aim of PLDD is to vaporize a small portion of the inner core. The ablation of a relatively small volume of the inner core results in an important reduction of intra-discal pressure, thus inducing reduction of disc herniation.
Advantages Of PLDD Laser Treatment 1. It's minimally invasive, hospitalization is unnecessary, patients get off the table with just a small adhesive bandage and return home for 24 hours of bed rest. Then patients begin progressive ambulation, walking up to a mile. Most return to work in four to five days. 2. Highly effective if correctly prescribed. 3. Processed under local, not general anesthesia. 4. Safe and fast surgical technique, No cutting, No scarring, Since only a tiny amount of disc is vaporized, there is no subsequent spinal instability. Different from open lumbar disc surgery, there is no damage to the back muscle, no bone removal or large skin incision. 5. It's applicable to patients who are at higher risk to open discectomy such as those with diabetes, heart disease, decreased liver and kidney functions etc.
