Axillary Reverse Mapping: Mapping and Preserving Arm Lymphatics May Be Important in Preventing Lymphedema During Sentinel Lymph Node Biopsy

Disruption of the blue ARM node because of proximity to the hot SLN may explain the surprisingly high rate of lymphedema seen after SLNB. Identifying and preserving the ARM blue nodes may translate into a lower incidence of lymphedema with SLNB and axillary lymph node dissection.
