Abstract (original English)

Postmastectomy chronic pain describes chronic pain in the anterior aspect of the thorax, axilla, and/or upper half of the arm present after surgical treatment of breast cancer and persistent for more than 3 months. The most common cause of this syndrome is damage to the intercostal brachial nerve. Current methods of treatment include medications, physical therapy, and peripheral nerve blocks. The literature lacks data regarding surgical interventions for intercostal brachial nerve pain in the postmastectomy and axillary dissection breast cancer patient. We discuss a case of a 47-year-old woman with left breast cancer status post-nipple-sparing mastectomy and sentinel lymph node biopsy complicated by refractory dysesthesias in the intercostal brachial nerve distribution. Axillary exploration demonstrated a surgical clip with an associated neuroma of a branch of the intercostal brachial nerve. Excision and repair resulted in immediate pain relief in the postoperative period. We propose a comprehensive treatment algorithm to address postmastectomy pain attributed to intercostal brachial nerve pathology.
