An Alternative Approach to the Intraoperative Indocyanine Green Angiography (ICGA) in reconstructive surgery

Indocyanine Green (ICG) is a nontoxic, near- infrared fluorescent dye that has been used for imaging since the 1950s to evaluate liver perfusion and in cardiology.1 It has more recently gained traction in other key areas of reconstructive surgery such as sentinel node biopsy in breast and melanoma skin cancers, lymphangiography in the surgical management of lymphedema and in assessing flap viability in free tissue transfers.1,2
