Functional anatomical hepatectomy guided by indocyanine green fluorescence imaging in patients with localized cholestasis: Report of four cases

Figure 1 Imaging examinations of Case 1. A and B: Preoperative magnetic resonance imaging showed a tumor approximately 35 mm in diameter located at segment V/VIII; C and D: Preoperative 3-dimensional reconstruction of the hepatic vein and portal vein revealed the tumor located at segment V/VIII, invading the right anterior branch of the portal vein; E: Partial fluorescence of segment V; F: Intraoperative ultrasound examination showed that the vein was compressed by the tumor; G and H: Postoperative specimen confirmed that the Glissonian pedicle was invaded by the tumor. T: Tumor; LHV: Left hepatic vein; MHV: Middle hepatic vein; RHV: Right hepatic vein; LBPV: Left branch of portal vein; RPPV: Right posterior branch of portal vein; RAPV: Right anterior branch of portal vein.
