Breast-conserving surgery, laparoscopic greater omentum harvest and vascular anastomosis was carried out orderly. The omentum was harvested laparoscopically, following breast-conserving surgery . Following the remove of resected omentum, the harvested greater omentum was poured by ice protection fluid from right gastric omentum artery. Besides, right arteriovenous vein of stomach omentum was dissected carefully under microscope. When operation started, front latissimus dorsi was separated from subaxillary incision, as well as the right thoracic dorsal artery and accompanying vein. Separated greater omentum was put on the subcutaneous deficient site of right breast incision and vascular pedicle was pulled through tunnel, reaching to the axillary incision. Under the help of microscope, vascular anastomosis between right stomach omentum arteriovenous and right thoracic dorsal arteriovenous was proceeded. Consequently, greater omentum was filled to shape the reconstructed breast. Finally, drainage tube and drainage strip were left at subcutaneous and subaxillary incision, respectively.
