Chapter 5 (Figure 5.1D, ±30 seconds after dye administration). This indicates a clear recognition of the cystic artery when positioned above liver parenchyma and the gallbladder if CW800‐CA is used. The TBR of the cystic duct versus liver parenchyma was respectively 3.2 for ICG (Figure 5.2B) and 2.3 for CW800‐CA (Figure 5.2D). Figure 5.1 Cystic artery imaging. Figures A and B are snap‐shots taken during ICG fluorescence laparoscopy experiments in pig 1: 70 A shows the anatomical view of the gallbladder and liver hilum. The associated ICG fluorescence image of the cystic artery is shown in B (cystic artery is indicated by the arrow, TBR = 0.5). Fluorescence angiography using CW800‐CA in pig 5 is presented in figures C and D: respectively the anatomical view and the associated fluorescence delineation of the cystic artery are presented (cystic artery is indicated by the arrow, TBR = 1.7). Complications No per‐ or postoperative complications regarding the extra‐hepatic bile ducts occurred. None of the pigs developed any adverse reactions to the injected ICG or CW800‐CA. No interference with intraoperative monitoring of Saturation of peripheral Oxygen (SpO2) was observed.
