Arterial Base Fluorescence Segmental Positive Staining

The patients with single HCC which is planned to received laparoscopic hepatectomy were involved. Procedures were performed in conventional angiography room. The celiac trunk was catheterized and a microcatheter was advanced into segmental hepatic artery branches which supplied the HCC. The 5cc 0.125 mg/cc ICG was injected from super-selective hepatic artery in operative room. A Near-Infrared laparoscope was used to detect the fluorescent signal to assess the correspondence between arterial-based fluorescence demarcation and ultrasound-based surgical demarcation.
