title: A left hepatectomy and caudate lobectomy combined resection of the ventral segment of the right anterior sector for hilar cholangiocarcinoma--the efficacy of PVE (portal vein embolization) in identifying the hepatic subsegment: report of a case.
abstract: This report presents a case of a left hepatectomy and a caudate lobectomy combined resection of the ventral segment of the right anterior sector for hilar cholangiocarcinoma using percutaneous transhepatic portal vein embolization (PVE). The patient was a 44-year-old man admitted to a local hospital with obstructive jaundice. He was diagnosed to have hilar cholangiocarcinoma and was referred to the hospital for further treatment. Cholangiography revealed stenosis of the left hepatic duct and the hilar bile ducts. The dorsal branch of the right anterior sector joined the right posterior branch and the tumor did not invade to the confluence of these branches. Arteriography and portography reconstructed by multidetector-raw computed tomography revealed the ventral branches of the right anterior sector, which separately diverged from the other right anterior branches. It was therefore necessary to perform a left hepatectomy and caudate lobectomy combined resection of the ventral segment of the right anterior sector to completely remove the tumor. Portal vein embolization was thus performed on the left portal vein and the ventral branches of the right anterior sector. Intraoperatively, when the hepatic artery was temporally clamped, the demarcation between the ventral segment and the dorsal segment of the right anterior sector could be clearly visualized. The planned surgery was performed safely. This case demonstrates that the utilization of PVE is useful for a difficult and intricate hepatectomy, which requires an accurate identification of a hepatic subsegment.
