Comment on “How to assess the volume of a DIEP flap using a free online calculator: the DIEP V (volume) method”

Razzano et al. developed a simple method to calculate the predicted volume of a DIEP flap for breast reconstruction.1 They hypothesized that the best representative shape for a DIEP flap was a truncated pyramid. They measured flap thickness using ultrasound (US), and used other variables including flap length and height to calculate the volume of a truncated pyramid-shaped flap. Great value must be given to this study because estimation of DIEP flap volume is crucial in surgical planning and execution for ultimately matching the volume of the breast being reconstructed, and it also can help decrease donor site complications.
