Mastectomy skin flap necrosis (MSFN) is a major complication after skin- or nipple-sparing mastectomy with a prevalence of 11–24%. 1 Indocyanine green angiography (ICGA) has been used in the last ten years in breast reconstruction surgery. ICGA involves real-time fluorescence imaging utilising a near-infrared camera after intravenous administration of the fluorophore, indocyanine green. There has been evidence that it has greater sensitivity than just clinical assessment to identify skin flaps with reduced perfusion.
