摘要 目的探讨多层螺旋CT动态增强扫描对肝细胞癌合并肝动脉-门静脉瘘的诊断价值。方法 52例肝细胞癌患者均进行肝脏3期动态增强扫描,延迟时间分别为27s、60s、90s。结果 52例肝细胞癌中,发现18例合并肝动脉-门静脉瘘,占34.6%(18/52),其中,中央型6例,周围型12例。中央型6例均发现门静脉主干和(或)1级分支内癌栓形成,周围型12例中,8例CT血管成像表现为门静脉2级以下分支连续性中断,呈"截断"征,4例CT血管成像表现为门静脉分支与肝动脉分支伴行,呈"双轨"征。本组病例中,肝动脉-门静脉瘘的检出率为34.6%,与文献报道偏低。结论多层螺旋CT动态增强扫描及血管重建对肝细胞癌合并肝动脉-门静脉瘘具有较高的诊断价值。
