Treatment of chest wall osteoradionecrosis with a contralateral breast Y-V flap: a case report

Abstract

Chest wall osteoradionecrosis, one of the most serious complications of radiation therapy for breast cancer treatment, is usually treated by wide debridement followed by coverage with a well-vascularized flap. However, the extent of radiation-induced injury and limits in performing wide resection of the injured bones often present challenges in treatment. Herein, we present our experience treating chest wall osteoradionecrosis with a contralateral breast Y-V flap in an 81-year-old woman. She was diagnosed with chest wall osteoradionecrosis and had grade 3 ptotic breasts. Redundant contralateral breast tissue was used for reconstruction to cover the wound. The flap was elevated in the subfascial plane after an inverted-T incision was made in the lower pole and inframammary fold of the contralateral breast, while preserving the perforators of the left lateral thoracic artery. The flap was spread using the Y-V advancement fashion to cover the wound. The patient was discharged 2 weeks after surgery. At 19 months postoperation, there were no complications or recurrence. The patient was satisfied with the short recovery time and surgical results. The contralateral breast Y-V flap allows simple and quick reconstruction, potentially expanding the available treatment options and therefore increasing flexibility in choosing a treatment plan for patients.
