原发性肝癌的供血动脉解剖分析

Analysis of supply arterial anatomy of primary liver cancer

目的：探讨供血动脉分型与肝癌的生物学特性的关系及其对临床治疗选择的意义。方法：分析和统计了419例巨块型原发性肝癌（＞10m）患者的动脉造影资料及临床资料。结果：根据供血动脉的数量的多少及形态，把原发性肝癌的供血动脉分为中央型、外周型、混合型和少供血型四种。前三型为多供血型，占71．84％，少供血型占28．历叽。中央型根据血管的分枝形态分为穿透型，树枝型，团状型三种亚型，分别占中央型的40．63％、52．60％、6．77％。外周型根据供血动脉的数量分为单枝型和多技型两种亚型，分别占外周型的30．43％和69．57％。外周型肝癌患者的1年和2年生存率较中央型和混合型高，而少供血型肝癌较多供血型低。结论：肝癌的供血动脉分型对肿瘤生物学特性的了解、临床治疗的选择及预后的判断具有重要的意义。

Objective:To study the relationship between the arterial supply types of primary liver cancer(PLC) and its biologic features and its clinical therapeutic selections.Methods:The arterial hepatic angiography and the clinic data were analysed and summed up in 419 cases with huge primary live cancer(PLC>10cm).Results:According to the mumber and shape of supply artery,the supply artery of PLC was divided four types:centr,periphery,mix and less blood supply types.The formerly three types were more blood supply types with 71.84%.The last type made up 28.16%.The center type was divided three subtypes:penetration,branch and ball which accounted for 40.63%,50.60% and 6.77% respectively according to the shape of supply arterial branch and the periphery type did two supbypes:single-branch and poly-branch which constituted 30.43% and 69.57% respectively according to the numbe of supply arterial branch.One0year and two-year survival rate in the periphery type were higher than the center type and the mix type.The less blood supply type lower than the more blood supply type.Conclusion:The arterial supply types of PLC were of great significance for leraning the biologic features,selecting the clinical therapies and judging the prognosis.
