This study was designed to demonstrate the predictive ability of quantitative indocyanine green fluorescence angiography for the delayed graft function after kidney transplantation. The study of 128 kidney transplant recipients identified the parameter ICG Ingress as a predictor of delayed graft function with sensitivity of 78.3% and specificity of 80.8%. This prospective diagnostic study, conducted in two German transplantation centres from November 2015 to October 2018, included 128 consecutive kidney transplantations. Intraoperative assessment of the allograft micro perfusion was performed by near-infrared fluorescence angiography with ICG; a software was used for quantitative analysis.
Conclusion Fluorescence angiography with ICG allows intraoperative quantitative assessment of micro perfusion during kidney transplantation. The parameter ICG Ingress reflects recipient and procedure characteristics and is able to predict the incidence of DGF.
