Summary
Postmastectomy pain syndrome (PMPS) is a neuropathic pain that can follow surgical treatment
for breast cancer, The antineuropathic medications (antidepressants and anticonvulsants) are
disappointing and have low success rate. Continues Radiofrequency lesioning has been reported
as treatment for several chronic pain conditions.The concept that the clinical effect of RF
was caused by formation of heat had not been challenged. Thermocoagulation of nerve fibers
would interfere with the conduction of nociceptive stimuli and pain would be relived.
Thoracic sympathectomy has been done for many painful conditions that includes complex
regional pain syndrome .It offers the benefit over stellate ganglion block as it blocks the
Kuntz fibers that connect to the brachial plexus roots without passing through stellate
ganglion.
