Surgical procedures and treatments:

The patient was in a supine position with the affected extremity spread. Then, routine disinfection was performed twice using iodophors. Sterile drapes and large drapes with holes were used and general anesthesia was satisfactory. A Fusiform incision was made at a position that is 3cm away from the margin of tumor, based on which the skin flap was separated from the inferior margin of clavicle to upper margin of costal arch, and from manubrium sterni to exterior margin of latissimus dorsi muscle. The separated skin flap was comparatively thin. The whole breast was excised, while pectoralis major/minor muscles were reserved. The pectoralis major muscle was raised by a large wire retractor and adipose tissues between pectoralis major muscle and pectoralis minor muscle were excised totally. Nervous pectoralis cranialis and blood vessels were reserved and no lymphadenectasis was seen. Peripheral lymph nodes of axillary vein were cut off using sharp incision, and adipose tissues were separated until reaching the apical axilla. No lymphadenectasis was observed. Thoracodorsal nerve, long thoracic nerve and vessels below the shoulder were reserved. Hemostasis was performed carefully and few hemorrhage volume was noticed. An elastic drainage tube (about 15cm) was inserted in the parasternal and anterior margin of latissimus dorsi muscle respectively, and vacuum aspiration was carried out. The skin was sutured and light tension was noted. On this basis, pressure dressing was conducted. The surgery was successful and general anesthesia was satisfactory. After the surgery, instruments were counted. The sample was submitted for pathological examination. The patient was transferred to the ward. Postoperative managements were performed such as fluid infusion and immune supporting therapy.
