摘要目的应用C臂CT肝动脉成像(C臂CTHA)研究肝镰状动脉(HFA)和萨佩氏上动脉(SSA)的出现率、解剖和分布。方法在此回顾性研究中共纳入220例病人,均自2011年1月—2012年12月因肝细胞肝癌初次通过C臂CTHA接受动脉介入治疗。HFA和SSA的出现率和起源通过C臂CTHA的横断面影像进行评估。HFA的5分量表和SSA的4分量表用来定义影像上两动脉的显示情况。结果总体HFA和SSA的出现率分别为95%(209例)和22%(49例),而在影像上两者明显显示的比例分别为62%(137例)和10%
Abstract Objective To study the incidence, anatomy and distribution of hepatic falx artery (HFA) and sappel artery (SSA) using C-arm CT angiography (C-arm CTHA) Methods In this retrospective study, 220 patients were enrolled in this retrospective study. All of them received arterial intervention for the first time through C-arm CTHA for hepatocellular carcinoma from January 2011 to December 2012. The incidence and origin of HFA and SSA were assessed by C-arm CTHA cross-sectional images. The 5-point scale of the HFA and the 4-point scale of the SSA are used to define the appearance of the two arteries on the image. Results The overall incidences of HFA and SSA were 95% (209 cases) and 22% (49 cases), respectively, whereas the apparent percentages of the two cases were 62% (137 cases) and 10%
