Thermocoagulation
Heat Probe Treatment of the Dorsal Root Ganglion
Selective Percutaneous Thermocoagulation of the Dorsal Root Ganglion
Thermocoagulation is precise treatment of affected dorsal root ganglions under local
anesthesia. After inserting the heat probe the physician verifies via computer whether
the probe is positioned exactly at the ganglion. Local anesthesia is again injected,
this time at the ganglion. The probe is then heated and the ganglion is cauterized.
Indications
- therapy-resistant radiating pain (for example arm or leg pain)
- failure of at least three periradicular therapies (treatment near the nerve roots)
- progressive vertebral joint arthrosis
- spinal stenosis (narrowing of the spinal canal)
- foramen stenosis (narrowing of the intervertebral foramen)
Value
Percutaneous thermocoagulation is precise treatment of specific nerves, a big advantage
over broad-action pharmacological therapy. The effects of percutaneous thermocoagulation
last for years in comparison to those of cryotherapy (freezing of nerves), which only last
a few months.
Advantage
This is a minimal invasive procedure, available on an out-patient basis. Surgical procedures
such as foraminotomy (widening of the intervertebral foramen) or hemilaminectomy
(partial removal of vertebral lamina) can be avoided using this procedure. Movement can be
regained shortly after treatment. Medical follow-up can also begin shortly thereafter.
Follow-Up
A program of physical therapy stressing isometric strength training and correct movement can
begin directly following treatment. This can be also be combined with electrical therapy,
bath therapy, heat applications and massage.
Work
The procedure does not greatly impede physical function. Light physical activity such as office
work is possible immediately after treatment.
Sport
Sports can be resumed relatively soon after treatment.
Results
Success rates of over 80% are reported in the national and international literature.
