肝动脉与肝外 collateral 之间或肝外 collateral 之间的吻合：血管造影观察。 （注：原文中“collateral”此处可能有误，推测可能是“collateral vessel”即“侧支血管”，但按照要求未做修改）

Transcatheter arterial chemoembolisation for hepatocellular carcinoma is widely carried out not only through the hepatic artery but also through the extrahepatic collateral pathways. Anatomically, there are many anastomoses between the hepatic artery and the extrahepatic collateral as well as among the extrahepatic collaterals. However, these anastomoses may not be shown on angiography because the anastomosing branches are too small. These anastomoses may not only interfere with effective control of hepatocellular carcinoma by transcatheter arterial chemoembolisation but also cause unexpected procedure-related complications. Therefore, radiologists should have sufficient knowledge of these underlying anastomoses. In this report, we present our angiographic images.
经导管动脉化疗栓塞术治疗肝细胞癌不仅广泛通过肝动脉进行，也通过肝外 collateral 途径进行。从解剖学角度来看，肝动脉与肝外 collateral 之间以及肝外 collateral 之间存在许多吻合支。然而，这些吻合支在血管造影中可能无法显示，因为吻合分支太小。这些吻合支不仅可能干扰经导管动脉化疗栓塞术对肝细胞癌的有效控制，还可能导致意想不到的与手术相关的并发症。因此，放射科医生应该对这些潜在的吻合支有足够的了解。在本报告中，我们展示了我们血管造影的图像。 （注：原文中“extrahepatic collateral pathways”中的“collateral”未明确其准确含义，暂直译为“collateral”，可能影响译文准确性，建议根据准确医学术语进一步调整完善）
