Portal vein puncture of segmentⅧ staining guided by laparoscopic ultrasound combined with 3DVT. A: 3D visualization reconstruction of liver; B: 3D visualization showing portal vein branches of segmentⅧ; C: 3D visualization showing segmentⅧ portal vein branches watershed (green area); D: laparoscopic ultrasound combined with 3DVT to guide ventral portal vein branch puncture of segmentⅧ (arrow); E: ICG fluorescence staining after successful puncture of ventral portal vein branch of segmentⅧ; F: Laparoscopic ultrasound combined with 3DVT to guide dorsal portal vein branch puncture of segmentⅧ (arrow); G: ICG fluorescence staining after successful puncture of dorsal portal vein branch of segmentⅧ; H: Resection line is labeled along the boundary of the segmentⅧ with indocyanine green fluorescence staining.
