The applications of indocyanine green dye angiography in plastic and reconstructive surgery continue to expand. LifeCell SPY-Elite (LifeCell Corp., Branchburg, N.J.) has allowed for the intraoperative assessment of blood flow within mastectomy skin flaps and burn wounds. Kanuri and colleagues recently performed a fiscal analysis of the intraoperative use of indocyanine green dye angiography for mastectomy reconstructive flaps in high-risk patients such as smokers, the obese, and diabetics, suggesting its utility for these patients. However, challenges remain in defining consistent and effective criteria for interpreting these measurements.
