Percutaneous cryoanalgesia for pain palliation: Current status and future trends - 28/04/21
Highlights |
• | Cryoanalgesia is a safe procedure with minimal risk of complications when performed with percutaneous approaches under imaging guidance. |
• | Computed tomography can serve as an ideal guiding technique due to its specific characteristics, including precise anatomic delineation, high spatial resolution and good tissue contrast. |
• | Patients may undergo repeated cryoanalgesia sessions as necessary without increased risk, as it is a safe procedure. |
Abstract |
Cryoanalgesia, otherwise termed cryoneurolysis, refers to application of extreme cold upon peripheral nerves for palliation of pain associated to nerve lesions or biomechanical syndromes of neoplastic and non-neoplastic substrate. Application of cryoanalgesia initiates a cascade of pathophysiologic events interrupting nerve conduction of painful stimuli without irreversible nerve damage. Cryoanalgesia is considered a safe procedure with minimal risk of complications when performed with percutaneous approaches under imaging guidance. In the era of an opioid overdose crisis, cryoanalgesia can be proposed as an alternative aiming at controlling pain and improving life quality. Imaging guidance has substituted open surgical and nerve stimulation approaches in nerve identification, significantly contributing to the minimally invasive character of percutaneous approaches. Ultrasound or computed tomography can serve as low cost, ideal guiding techniques due to their abilities for precise anatomic delineation, high spatial resolution and good tissue contrast. The purpose of this review is to become familiar with the most common imaging guided percutaneous cryoanalgesia indications, to learn about different technical considerations during performance providing the current evidence. Controversies concerning products will be addressed.
