Oncoplastic reconstruction of a large chest wall defect using dual fasciocutaneous flaps: A case report

Large chest wall defects in the context of breast cancer or its sequelae can be challenging to address. Oncoplastic techniques have been demonstrated to be safe and feasible options for immediate reconstruction. We describe the use of dual fasciocutaneous flaps for coverage following resection of a large chest wall mass in an area with a remote history of radiation therapy.

A 67-year-old woman with a distant history of bilateral mastectomies and adjuvant chemoradiation for Stage IIB triple negative invasive ductal carcinoma presented with an enlarging left chest wall mass and chronic wound. The mass was excised with adequate margins, and the resulting defect was reconstructed with two locoregional fasciocutaneous flaps. Pathology returned negative for malignancy and follow-up demonstrated viable flaps that were healing well.

Fasciocutaneous flaps are one of many techniques for breast reconstruction and offer advantages of a relatively superficial dissection, shorter operative time, and decreased risk of functional impairment. They are consequently an attractive option for patients with multiple comorbidities and high risk of perioperative complications. Historically used for immediate reconstruction at the time of oncologic resection, we present its successful use decades after the index cancer operation to manage a chest wall defect secondary to radiation injury.

Oncoplastic reconstruction with dual fasciocutaneous flaps is a feasible option for a large chest wall defect in the setting of previous radiation.
