摘要目的：报道18例肝癌TAE后发生的少见并发症诸如：门静脉狭窄闭塞、肝段叶萎缩、肝内胆管扩张和囊肿样变等，分析其发生原因。 资料和方法：18例患者中男15例、女3例，平均年龄46.3岁(34-71岁)，平均TAE次数为2.7次(2?5)，中位生存期17.7个月(5-64月)；均经过SCT双期扫描。 结果：按照本组入选标准：18例中于TAE后发生肝内胆管扩张18例(18/18)和囊肿样变6例(6/18)，门静脉分支狭窄闭塞18例(18/18)，肝段叶萎缩15例(15/18)。结论：TAE后胆管小动脉受损是发生胆系损伤的重要因素；TAE后对门静脉分支的损伤是导致门静脉分支狭窄闭塞的主要原因；TAE后发生的肝段叶萎缩与上述因素非常密切。
