Resection of hepatocellular carcinoma in a patient with congenital anomaly of the portal system.
Hepatic resection in a patient with an anomalous portal vein system is presented. A 53-year-old man was referred to our hospital for hepatic resection. Preoperative computed tomography (CT) and angiography demonstrated that the umbilical portion of the portal vein gave off major branches to the right anterior segment, and the hepatic tumor was located on the dorsal side of one of the right anterior portal branches near the umbilical portion. Partial hepatic resection was performed using the indocyanine green staining technique under operative echo guidance. Limited hepatic resection was indicated due to the patient's poor hepatic reserve function. His postoperative course was uneventful. This case emphasizes the importance of delineating the hepatic vascular anatomy before and during operation, especially in the case of an anomalous portal vein system.
