Lumbar Artery Perforator Flaps in Autologous Breast Reconstruction

The lumbar artery perforator (LAP) flap should be considered for autologous breast reconstruction when a patient's abdomen is unavailable as a donor site. The LAP flap can be harvested with dimensions and volume of distribution that facilitate the restoration of a naturally shaped breast with a sloping upper pole and maximal projection in the lower one-third. Harvest of LAP flaps lifts the buttocks and narrows the waist and, consequently, aesthetic improvement in body contour is generally achieved with these procedures. Although technically challenging, the LAP flap is a valuable tool in the practice of autologous breast reconstruction.
