Unilateral and Bilateral DIEP Reconstruction
For the sake of symmetry, the DIEP flap is taken from across the abdomen, whether or not the tissue will be used to reconstruct one or both of your breasts. If you are having a bilateral reconstruction, the abdominal tissue will be divided between the two breasts. If you have a unilateral reconstruction, any leftover tissue will be discarded after the procedure.
Once you have had DIEP surgery, you cannot have it again. If you have one breast reconstructed with a DIEP flap and later need or desire reconstruction of the other breast, you will have to use tissue from a different area of your body, or use an implant.
