Abstract
Managing chronic axillary seroma after breast cancer surgery is troublesome because of the challenges in obliterating the seroma pocket and the possible injury to the axillary neurovascular bundles during the procedure. Using the muscle sling technique, we successfully managed an axillary chronic seroma patient after mastectomy with a latissimus dorsi musculocutaneous (LDMC) flap. A 64-year-old woman with right breast cancer underwent radical mastectomy with axillary lymph node dissection 17 years ago. A mass of chronic seroma was observed in the right axilla 1 year postoperatively and gradually increased in size. The refractory seroma was excised. The LDMC flap was designed to obliterate the pocket, rotated counterclockwise, and fixed to the upper boundary of the pectoralis major in a U-shaped sling. In this way, the direct suture of the flap to the vessels-crossing axillary apex could be avoided, and the flap’s lymphatic-rich fat tissue promoted alternative lymphatic drainage that improved lymphedema.
