We present 2 patients with biliary compression by hepatic artery aneurysms and, for the first time, a cholangiographic demonstration of this rare cause of extrahepatic obstruction. The clinical features of hepatic artery aneurysms and modalities available for their diagnosis are reviewed. The cholangiographic appearance of smooth, gradual tapering of the biliary tree, although nonspecific, is not typical of the more commonly encountered bile duct carcinoma and should alert the investigator to the possibility of this uncommon diagnosis. Angiography must still be considered the procedure of choice but is unlikely to be performed without the necessary index of suspicion, either on clinical or radiologic grounds.
我们报告了2例因肝动脉瘤导致胆管受压的患者，并首次通过胆管造影证实了这种罕见的肝外梗阻原因。本文回顾了肝动脉瘤的临床特征及可用的诊断方法。胆管造影显示胆管树呈平滑、逐渐变细的表现，虽然不具有特异性，但并非更常见的胆管癌的典型表现，应提醒研究者考虑这种罕见诊断的可能性。血管造影仍被认为是首选检查方法，但如果没有基于临床或影像学的必要怀疑指标，不太可能进行该项检查。
