Laser Decompression Cervical Spine PLDD Surgery
Laser For PLDD(Percutaneous Laser Disc Decompression)
PLDD was first introduced in the 1980s and the concept is based on
the fact that a small reduction in volume of the nucleus pulposus
results in a significant reduction in intradiscal pressure. This is
achieved by introducing an optical fiber into the intervertebral
disc under image-guidance and local anesthesia and laser energy is
released, vaporizing a small volume of the nucleus pulposus.
Treatment of the first patient with PLLD took place in 1985 and
from then until 2011, more than 30,000 patients have been treated
with this procedure. US Food and Drug Administration (FDA) approved
PLDD in 1991.
Percutaneous laser disc decompression procedure
Percutaneous laser disc decompression procedure A CT was performed
in order to locate the level of the affected disc, to guide needle
placement exactly within the nucleus pulposus and to visualize
Cherylas 30W 980nm diode laser, portable, operated in pulsed. Laser
energy was transmitted through a contact optical fiber (400 m),
sterile and flexible. After disinfection of the area, local
anesthetic with lidocaine was injected under CT guidance at the
entry point of the needle a through the deep fascia and muscle
layers, under CT guidance, a fine hollow 18G needle was then placed
centrally in the nucleus pulposus of the intervertebral disc, The
needle was removed and, once verified, a 400 m sterile optical
fiber with a proximal mark to prevent penetration of the tip more
than 1 cm beyond the end of the needle was inserted into the
needle.15 W of laser energy were delivered in 0.5---1 s pulses with
4---5 s pauses to allow heat dissipation and avoid or minimize the
pain caused by the heat. Careful monitoring of patient discomfort
is absolutely necessary, and the pulse rate should be increased if
the patient experiences discomfort.The laser energy delivered
ranged between 1000 and2000 J, depending on the level of the
herniated disc,and the formation of vaporized gas within the disc
was also valuated.
