肝动脉瘤是一种罕见疾病，本文报告４例肝动脉瘤，其中肝外动脉瘤１例，肝内动脉瘤３例。腹部平片显示上腹部环形钙化，钡餐检查十二指肠外压变形，Ｂ超、ＣＴ和ＭＲ扫描显示胰头上方有肿块，都应考虑本病，血管造影可确定诊断。作者认为肝外动脉瘤可采用动脉瘤切除或瘤体近远端动脉结扎，不需血管重建。肝内动脉瘤治疗方法很多，其最好治疗方法是肝内动脉栓塞。 Hepatic aneurysm is a rare disease. This article reports 4 cases of hepatic aneurysms, including 1 extrahepatic aneurysm and 3 intrahepatic aneurysms. Abdominal plain film shows epiglottic circular calcification, barium meal examination duodenal external pressure deformation, B-ultrasonography, CT and MR scan showed a mass above the pancreatic head, should consider this disease, angiography can confirm the diagnosis. The authors believe that extrahepatic artery aneurysms can be resected by aneurysms or by ligation of the proximal and distal arteries of the tumor without revascularization. There are many methods for treatment of intrahepatic aneurysms. The best treatment is intrahepatic artery embolization.
