Utilizing Indocyanine Green Dye Angiography to Detect Simulated Flap Venous Congestion in a Novel Experimental Rat Model

Abstract

ICG angiography can detect venous congestion in a rat lower extremity model reliably at occlusion rates ≥ 85%. This method may offer surgeons an intraoperative diagnostic tool to identify venous congestion at extremely early time points, allowing for immediate intervention. Further investigation and characterization is warranted in a larger animal model before clinical adaptation.
