| Abstract: | Axillary reverse lymphatic mapping (ARM) is a surgical technique that was first described in 2007 as a method for preserving the lymphatic drainage of the arm during sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) for breast cancer. We found that the ARM technique had several limitations that include a poor success rate for identification of arm lymph nodes (ARM nodes) and lymphatics. The occurrence of common lymphatic drainage pathways of the arm and the breast in a subset of patients also raises concerns regarding its oncological soundness. Furthermore, the effectiveness of the ARM procedure in reducing lymphedema risk in breast cancer patients that undergo a variety of treatments, has yet to be clearly defined. |
