BREAST RECONSTRUCTION FOLLOWING MASTECTOMY WITH FAT GRAFTING
With recent advances in fat grafting techniques, it is now possible to reconstruct a breast following mastectomy with your own fat tissue.
The procedure is performed by using a variety of procedures, including external expansion or BRAVA® which stretches the skin making space for the fat grafting. Tissue expansion can also be performed with saline injections prior to fat grafting.
Fat grafting is performed by harvesting fat in the same way that liposuction is performed. Fat is usually harvested from the abdomen, flanks or thighs, resulting in improved contour to the body.
The fat is specially prepared, removing oil that resulted from the fat grafting procedure. The fat is then mixed with PRP (platelet rich plasma) or PRF platelet rich fibrin. The platelet rich plasma is harvested from your own blood; the red cells are removed leaving the concentrated plasma which helps with fat graft survival. The result is that you retain your own tissue with sensation.
WHAT TO EXPECT
Usually two to three fat grafting sessions are required to achieve the desired result. Fortunately, most of these cases are covered by insurance.
The procedure can be initiated at the time of the mastectomy. Following mastectomy, fat can be injected into the underlying tissues and partially into the skin flap. Alternatively, a temporary adjustable implant can be placed at the time of the mastectomy. Subsequent fat grafting can then be performed, reducing the volume of the adjustable implant as fat replaces the volume. Finally, the adjustable implant can be removed.
Alternatively, following the initial fat grafting procedure, external expansion can be carried on for several weeks until the next fat grafting procedure is performed.
- If the patient has insufficient fat that can be harvested for the procedure.
- Smoking. Smoking increases the risk of bleeding, poor wound healing and poorer fat survival.
- Chemotherapy, particularly Herceptin interferes with revascularization of the fat grafts. Aspirin and other anticoagulant medications, including herbal supplements that are known to have anticoagulant effects such as fatty acids, ginkgo biloba and vitamin E.
- Patients who do not wish to have multiple procedures.
