Purpose
Cryoneuroablation,
also known as cryoanalgesia or cryoneurolysis,
is a specialized technique of anesthesia and interventional radiology,
providing long-term pain relief (1).
Lloyd et al proposed that cryonalgesia was superior to other methods of peripheral nerve destruction,
including alcohol and phenol neurolysis or surgery (2).
The application of cold to nerve creates conduction blocks,
similar to the effect of local anesthetics (3,
4,
5).
Clinical applications of cryoanalgesia in oncology extend from its use in chest wall pain after thoracic metastases,
pathologic rib fractures; post-thoracotomy pain or pain due to percutaneous drainage tubes (6).Persistent chest wall pain is common after thoracotomy and is usually caused by recurence or progression of malignancy.
The purpose of this study was to prospectively determine the safety and effectiveness of percutaneous cryoneurolysis for pain reduction in patients with painful metastatic lesions involving chest wall and failure of third level opioid treatment.
