Breast-conserving treatment (BCT) leads to a progressive and deteriorating breast deformity. Fatgrafting is ideal for breast reconstruction after BCT. The most frequently utilized technique for fat processing is centrifugation. The PureGraft device (Cytori Therapeutics, USA) is a new method that involves washing and filtering the fat to prepare the graft. The investigators compared the subjective and objective outcomes of two fat-processing methods, centrifugation and PureGraft filtration.
