PLDD is a minimally invasive procedure that does not require general anesthesia. The laser is delivered through a needle inserted into the disc and guided by computed tomography (CT) and fluoroscopy.
CT fluoroscopy involves creating images with X-rays that are further enhanced by contrast dye. This allows physicians to see precisely where to place the needle used in PLDD.
Unlike conventional discectomy, the protruding piece of disc compressing nerve roots is not surgically removed. Instead, once the needle is in place, laser energy is delivered through the needle and into the disc.
This energy–in the form of heat–reduces the pressure inside the disc. The protruding piece of disc is therefore sucked back through the outer layer of the disc, relieving pressure on the nerve roots.
Laser disc decompression is an outpatient procedure, meaning the patient may leave the hospital or surgery center within 24 hours of surgery. General anesthesia is not used so the patient is never unconscious during the surgery. The area around the disc to be decompressed is numbed with local anesthesia.
