The Lymphedematous Limb as a Donor Site for Breast Fat Grafting

Breast cancer–related lymphedema results in chronic upper limb swelling with subcutaneous deposition of fluid and fibroadipose tissue. Morbidity includes psychosocial distress, infection, and difficulty using the extremity. Operative management includes excisional procedures such as suction-assisted lipectomy to reduce abnormal subcutaneous fibroadipose tissue to improve limb volume. Patients who have had postmastectomy breast reconstruction often benefit from fat grafting. This report introduces the concept of fat grafting the breast using the lymphedematous arm as a donor site. This technique improves the volume of the limb by removing the excess subcutaneous adipose, and at the same time reconstructs the breast without adding a donor site not related to the breast cancer–related lymphedema.
