The DIEP flap or deep inferior epigastric artery perforator flap allows the blood vessels that perfuse the skin and fat on the lower abdomen to be transferred to another part of the body. When the breast has been removed for cancer as in a mastectomy, the skin on the lower abdomen is an optimal choice to replace this missing tissue.
In athletic patients, it is helpful to preserve as much muscle as possible on the abdomen. However, it is important that the operation be done safely and to replace the missing tissue on the breast.
