Abstract
Breast cancer is the leading cause of death in females worldwide. Radiotherapy plays an important role for locoregional control in the comprehensive management of breast cancer. Chronic radiation-induced ulcer of the axilla can occur, and it is complicated to treat for these lesions. The application of a thoracodorsal artery perforator flap offers many advantages to be one of the most efficient treatments for radiation-induced ulcers of the axillary region. We introduce a series of 5 patients with radiation-induced ulcers of the axilla treated by using a thoracodorsal artery perforator flap. The mean operative time was 190 minutes. During at least a two-year follow-up, no complication has been found, and the patient has achieved good cosmetic result without movement limitation of the upper limb.
