From: Laparoscopic ultrasound-guided superselective portal vein injection combined with real-time indocyanine green fluorescence imaging and navigation for accurate resection of localized intrahepatic bile duct dilatation: a case report

Fig. 2

a Portal vein branch of the target hepatic segment was super-selected and punctured with a 18G needle by intraoperative laparoscopic ultrasound guidance (black dotted line), then an injection of 0.05 mg indocyanine green was performed gently (0.025 mg/ml, red arrow); b Visualization of the lesion area by fluorescence imaging after the intraoperative portal vein injection of indocyanine green (white arrow); c Real-time indocyanine green fluorescence imaging (ICG-FI) enabled the visualization of overall structure of the lesion and intrahepatic surgical boundary during operation (white arrow)
