Review of Donor Site Complications Among Different Intra-Abdominal Vascularized Lymph Node Free Flaps: Future Tendency of Application Based on Anatomical Considerations

Transfer of lymph node flap (LNF) has become popular in surgical management of lymphedema as a means of providing physiologic lymph drainage. A variety of donor site options have been reported, and their effects are still under investigation, but a consensus is to minimize the donor site complications.
