Axillary Reverse Mapping
During axillary lymphadenectomy, the ARM technique will be incorporated. Prior to surgery, periareolar Tc99 injection will be performed to identify breast sentinel lymph nodes. Fifteen minutes before surgery, 2 mL of indocyanine green tracer will be injected subcutaneously in the medial intermuscular region of the ipsilateral upper limb, followed by gentle massage for 5 minutes. Standard axillary lymphadenectomy will then be performed, preserving ARM lymph nodes located below the axillary vein and lateral to the thoracodorsal pedicle.
