Pectoralis major interposition flap: A new technique for treatment of severe peri-ductal mastitis

Abstract

Background Peri-ductal mastitis is an uncommon benign disorder of the major lactiferous ductal system of the female breast. It can be a very difficult problem to treat and may cause significant patient morbidity. We describe a new technique, involving use of the pectoralis major muscle flap, for treating recurrent sub-areolar abscess refractory to standard surgical treatment. Method Three patients who underwent this new technique for severe refractory peri-ductal mastitis at Calvary Hospital, Canberra are presented. Results These patients who had recurrent peri-ductal mastitis with abscess and fistula formation on a monthly basis despite numerous courses of antibiotics and surgical procedures experienced no further recurrences following pectoralis major interposition flap surgery at 42, 32 and 22 months follow-up respectively. Conclusion This new technique may provide an opportunity to control these otherwise difficult to treat cases of severe recurrent peri-ductal mastitis where standard surgical methods have failed.
