目的:探讨中、晚期肝癌变异、寄生性供血的产生机理。材料和方法:本研究收集TAE治疗资料完整的中、晚期肝癌340例,对其血管造影表现进行分析。结果:变异供血93例(占27.4％);寄生供血99例(占29.1％);变异合并寄生供血12例(占3.5％)。结论:肝癌寄生性动脉供血的发生与肿瘤的大小有关(P<0.01)。与肿瘤生长部位有关;变异供血因早期胚胎异常所致。
Objective: To investigate the mechanism of hepatoma variation and parasitic blood supply in middle and late stages. Materials and Methods: In this study, 340 patients with advanced hepatocellular carcinoma with TAE were collected and their angiographic findings were analyzed. Results: There were 93 patients (27.4%) with variable blood supply, 99 patients (29.1%) with parasitic blood supply, and 12 patients (3.5%) with variable parasitic blood supply. Conclusion: The incidence of hepatic artery parasitic arterial blood supply is related to the size of the tumor (P<0.01). It is related to the site of tumor growth; variations in blood supply are due to early embryonic abnormalities.
