Brief 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.

Outcome Measures

Primary Outcomes (1)

  • The intensity of pain

    The intensity of pain measured by visual analogue score

    up to 3 months after the procedure

Secondary Outcomes (3)

  • The changes in analgesics consumption

    1 month, 2 month and 3 month post-procedure

  • The changes in mid-arm circumference

    1 month post- procedure

  • The changes in post-menopausal hot flashes if it was a pre-procedure complaint

    3 month post- procedure

Study Arms (2)

interventional group

EXPERIMENTAL

patients will receive Radiofrequency thoracic sympathectomy then will receive pregabalin ,tramadol,and tricyclic antidepressants

Procedure: radiofrequency thoracic sympathectomyDrug: pregabalin ,tramadol,and tricyclic antidepressants

control group

ACTIVE COMPARATOR

patients will receive pregabalin ,tramadol,and tricyclic antidepressants

Drug: pregabalin ,tramadol,and tricyclic antidepressants

Interventions

Under fluoroscopic guidance thoracic sympathectomy will be done as follow 1. antroposterior view of upper thoracic vertebrae ,cephalo-caudal adjustment of C - arm until aliment of endplates of T2 and T3 2. oblique view 20 degree under tunnel view RF 10cm 20G 1mm active tip needle is introduced intimately related to vertebral margin 3. the depth of the needle will be determined under lateral fluoroscopic view the needle is advanced step by step hugging the lateral vertebra l margin until the tip of the needle situated at the middle of the vertebral body . RF lesion 2min 80c will be done and needle is rotated 90 degree on both sides and another two lesions will be done at the end of the procedure 2ml of lidocaine and 20mg of triamcinolone will be injected at each level Post procedure analgesic protocol consisted of either increase or decrease, according to intensity of pain by 50 mg pregabalin and 50 mg tramadole and 25 mg tryptazole, individualized for each patient.

interventional group

patient will receive anti neuropathic medications
