作者报告310例中闻人的肝动脉解剖类型。本组材料发现89例(28.7％)肝动脉解剖变异。其中男性71例(27.1％),女性18例(37.5％)。异位自胃左动脉者46例(14.8％),异位自肠系膜上动脉者37例(11.9％),异位自腹主动脉者4例(1.3％),异位自右肾动脉者2例(0.6％)。各种变异在性别分布无显著性差异。从而建议根据肝动脉来源,将肝动脉解剖分为腹腔动脉供血型,肠系膜上动脉供血型和其它动脉供血型三类。对晚期肝癌肝动脉的解剖变异的临床意义进行了讨论。
The authors reported 310 cases of hepatic arterial anatomy. This group of materials found 89 cases (28.7%) anatomical variations of the hepatic artery. There were 71 males (27.1%) and 18 females (37.5%). There were 46 cases (14.8%) with ectopic left gastric artery, 37 cases (11.9%) with ectopic superior mesenteric artery, 4 cases (1.3%) with ectopic abdominal aorta, and 2 cases with ectopic right renal artery. (0.6%). There was no significant difference in the distribution of various variants in gender. Therefore, according to the source of hepatic artery, it is suggested that the hepatic artery dissection be divided into celiac artery blood supply type, superior mesenteric artery blood supply type and other arterial blood supply type. The clinical significance of the anatomical variation of hepatic artery in advanced hepatic cancer is discussed.
