Flap Reconstruction Without Abdominal Tissue: PAP and LAP
You wanted reconstruction with your own tissue, and then you were told you don't have enough abdominal fat, or a prior tummy tuck took the DIEP flap off the table. That is not the end of natural tissue reconstruction. It is where the alternatives begin.
What if I'm not a candidate for a DIEP flap?
The DIEP flap, which uses tissue from the lower abdomen, is the most widely performed autologous reconstruction and the gold standard for natural tissue reconstruction. It offers reliable volume, favorable scarring, and a low complication rate.
But not every woman is a candidate. Some do not have enough abdominal tissue to match their breast volume. Others have had prior abdominal surgery, such as a tummy tuck, that compromises the blood vessels the flap requires. For these women, alternative donor sites can achieve excellent results. We consider the PAP flap and the LAP flap the two best alternatives. Drs. Weichman and Thanik have extensive experience with both, and have been involved in advancing PAP flap surgery since its earliest cases.
What is a PAP flap?
The PAP flap (profunda artery perforator) uses tissue from the posterior thigh. First described around 2010, it is particularly well suited to thinner women seeking smaller-volume reconstruction. The donor site scar sits in the natural crease below the buttock or along the inner thigh, where it is well concealed, and long-term outcomes are consistently good.
What is a LAP flap?
The LAP flap (lumbar artery perforator) is a newer option using tissue from the lower back and "love handle" area. It typically provides more volume than the PAP flap, making it a strong choice for women who need larger reconstructions or who lack sufficient tissue at other donor sites.
We will be direct about the tradeoffs: LAP flap surgery is more technically demanding than other autologous procedures. It requires vascular grafts, typically harvested from the abdomen, which adds complexity. Recovery is longer and the overall complication rate is slightly higher than with DIEP or PAP flaps. It is best suited to well-informed, motivated women committed to reconstruction without implants who have discussed the tradeoffs in detail with their surgeon.
Choosing the right donor site
The decision weighs your anatomy, the volume you need, your surgical history, and your priorities. These flaps also matter in conversion from implants and in repairing a failed reconstruction, where the abdomen has often already been used or lost. Being told once that you were not a flap candidate is a data point, not a verdict; donor site options have expanded, and so has what is possible.
FAQ
Yes. A tummy tuck usually rules out the DIEP flap because the necessary abdominal blood vessels have been divided, but the thigh (PAP) and lower back (LAP) remain fully available donor sites.
Often, yes. Women who are thin for a DIEP frequently have adequate posterior thigh tissue for a PAP flap, and the LAP flap can recruit volume from the lower back. Candidacy is assessed per donor site, not once for all of them.
The PAP uses posterior thigh tissue, suits smaller-volume reconstruction, and has a well-concealed scar. The LAP uses lower back tissue, provides more volume, and is more technically complex with a longer recovery.
In appropriately selected women, yes. Each donor site has its own scar pattern, volume, and recovery profile, and matching the flap to the woman is what determines the outcome.

our philosophy
After years in clinical practice, we have watched patients complete treatment, receive a clean bill of health, and still feel like strangers in their own bodies. Fragmented care, time-pressured appointments, and a healthcare system focused on disease management rather than whole-person recovery leaves too many people stranded between surviving and truly living.
