Description of the procedure

Cryoablation is a minimally invasive therapeutic procedure that provides a long-lasting pain relief effect for the patient by affecting the pain pathway at the level of sensory nerves by applying low temperatures. It is most commonly used in the treatment of lower back pain (intervertebral or facet joints, SI joint), but also for other indications. By applying low temperature, the sensory functions in certain peripheral nervous system structures are temporarily interrupted. The mechanism of action, in principle, is very similar to the effect of local anaesthetics, but the effect is much longer. This is achieved both because of the impact on the conductivity of the nerve fibres and because of the disruption of small blood vessels feeding the nerve tissue. Disrupting the external nervous structure does not damage the internal nerve fibres and cells, which maintain their ability to regenerate within a period of approximately 6 months after the procedure. After nerve regeneration, full recovery of nerve functions occurs, often without the existence of original painful syndromes. If the pain returns, the procedure can be repeated.

Benefits of the procedure

The outpatient procedure is performed under X-ray or ultrasound monitoring, under local anaesthesia, and it takes up to 10 minutes. The procedure is also suitable for patients with implanted pacemakers.

• high efficiency in pain relief
• no risk of secondary pain
• no risk of damage to vessels or development of scars
