摘要：

目的:分析胆管癌栓经皮肝穿刺胆管造影术(Percutaneous transhepatic cholangiography,PTC)的影像特点,以提高胆管癌栓的诊断水平。资料与方法:回顾性分析27例经病理或临床证实为胆管癌栓的PTC图像特点。患者年龄(49.81±7.27)岁。27例患者均在超声或DSA引导下选择单侧或双侧穿刺入路行PTC,留置内引流管或外引流管,引流3～5 d后复查PTC以观察影像变化情况。结果:27例胆管癌栓均于胆管腔内可见充盈缺损影,26例充盈缺损及相应水平胆管呈"膨胀性"改变。24例癌栓近端胆管呈软藤样扩张,3例呈枯树枝样改变,癌栓远端胆管均无扩张。9例充盈缺损的轮廓完全显示,其余18例部分显示。21例引流前后所见充盈缺损范围基本一致,6例引流后充盈缺损范围较前缩小。根据其累及范围分为3型:Ⅰ型2例,Ⅱ型22例,Ⅲ型3例。结论:胆管癌栓有特异性的PTC表现,PTC对胆管癌栓的诊断有重要价值。
