Abstract

The present invention relates to a method and a system for providing a perfusion based complication prediction, a clinical decision support system, and a computer program.The method comprises loading ICG perfusion image time series of a patient's organ receiving blood supply from the operated on blood vessel from times T1, T2 and T3 from a database, T1 denoting a time before clamping shut the blood vessel, T2 denoting a time after fully clamping shut the blood vessel and before repair of the blood vessel and T3 denoting a time after finishing the repair of the blood vessel and removing the clamp, normalizing the T1, T2 and T3 perfusion image time series to a common standard and extracting ICG fluorescence intensity time series for a plurality of regions of interest on an organ supplied by the vessel, taking a set of one or more collective characteristics of the fluorescence intensity time series at T1 and T2 as benchmarks for unobstructed and maximally obstructed blood supply, respectively, evaluating the same set of collective characteristics of the fluorescence intensity time series at T3 with respect to its collective proximity to those of the perfusion image time series at T1 and T2, respectively, the proximity to either being taken as an indicator for complication prediction, and outputting a complication prediction.
