Indocyanine Green Fluorescence-guided Sentinel Node Biopsy in Breast Cancer Within a North African Population: a Retrospective Study

Under general anesthesia 5 ml at 2.5mg/ml of Infracyanine ® (Laboratoire SERB; France) were injected circumferentially around the areola. Two ml of patent blue-V dye (Laboratoire Guerbet, Aulney-Sous-Bois, France) were injected in combination in the cohort of patients undergoing the procedure after primary chemotherapy. This was followed by a breast massage to facilitate absorption into the lymph vessels, then the surgical lights were turned off and image were obtained under near-infrared light using a first generation Near Infra Red (NIR) device \[K\]. Course of subcutaneous lymphatic drainage pathway fluorescence was followed up to where it disappeared to enter to deeper axilla and an incision was performed at that place. Lymphatic duct identification using the NIR camera allowed localization and removal of the sentinel lymph node(s).
