Indications and Technique of Thoracic(2) and Thoracic(3 )Neurolysis.

This article reviews the technique of thoracic (T)(2) and T(3) sympathetic ganglion block and neurolysis. Historic aspects of this technique are described. The concept of radiofrequency thermocoagulation (RFTC) of T(2) and T(3) is discussed and the technique is detailed. This procedure is useful for complex regional pain syndrome (CRPS), vascular compromise, and neuropathic pain syndromes of upper extremities. It is an alternative to stellate ganglion ablation and may be useful for patients with sympathetically maintained pain who have persistent pain after stellate ganglion procedures.
