根据肿瘤所在的肝的区段不同,可将其分为中央型和周围型肝肿瘤。中央型肝癌是指与门静脉分叉部、三支主肝静脉同下腔静脉汇合部及肝后下腔静脉主干的距离在1cm范围以内的肝脏肿瘤。目前,中央型肝癌的治疗方法主要有三种:介入治疗、射频消融治疗和传统外科手术治疗。手术切除是中央型肝癌的首选方法。但由于中央型肝癌紧邻肝脏的大血管和总胆管,既往传统手术危险性大、难度高、切
According to the segment of the liver where the tumor is located, it can be divided into central and peripheral liver tumors. Central liver cancer refers to a liver tumor whose distance from the portal vein bifurcation, the three main hepatic veins with the inferior vena cava junction, and the posterior inferior vena cava trunk is within 1 cm. At present, there are three main treatments for central liver cancer: interventional therapy, radiofrequency ablation therapy and traditional surgical treatment. Surgical removal is the preferred method for central liver cancer. However, due to the central hepatocellular carcinoma adjacent to the large blood vessels and the common bile ducts of the liver, the previous traditional surgery has a high risk and is difficult to cut.
