In some women the superficial vessels in the abdominal fatty tissue provide the dominant source of blood flow to this region. In those cases the SIEA (superficial inferior epigastric artery) may be chosen as the source of blood supply for the borrowed tissue necessary to reconstruct the breast. The procedure is otherwise the same as the DIEP procedure and represents a second choice for women whose superficial vessels are more dominant than the deep inferior epigastric perforators (DIEP’s).
Perforator flaps represent the state of the art in breast reconstruction. Replacing the skin and soft tissue removed at mastectomy with soft, warm, living tissue is accomplished by borrowing skin and fatty tissue from the abdomen or hip. This is accomplished without sacrificing muscles and strength as compared to less sophisticated techniques.
