How to assess the volume of a DIEP flap using a free online calculator: the DIEP V (volume) method,,✰✰✰,✰✰✰✰

Among the few methods available, none is able to determine accurately the volume of a DIEP flap. Specimen weight is commonly used to assess the amount of flap needed to reconstruct a breast, but the density of breast is different from that of abdominal tissues; therefore, the volume should be used as a unique unit of measure. The purpose of this study was to provide a simple method to calculate the predicted volume of a DIEP flap in order to match the volume of the breast being reconstructed.
