肝动脉瘤的诊断和治疗四例报告

Diagnosis and treatment of hepatic artery aneurysm report of four cases and areview of the literatures

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 artery aneurysm is a rare disease.Four cases including one extrahepatic artery aneurysm and three intrahepatic artery aneurysms are reported by the authors;Since the clinical features of hepatic artery aneurysm are non-specific,the clinical diagnosis of aneurysm is difficult.Plain abdominal x-ray film reveals a ring shape calcification in the upper abdomen.Barium GI series may show a deformed duodenum,as a result of compression,ultra-sound scan,CT scan and MR scan often reveal a mass above the head of pancrease,These are suggestive to the disease.The diagnosis of hepatic artery aneurysm can be confirmed by angiography。The authors proposed that extrahepatic artery aneurysm could be excised or be treated by ligating proximal and distal arter of the aneurysm body.Vascular reconstruction is unnecessory.There are many methods in the treatment of intrahepatic artery aneurysm,but the best one is intrahepatic arterial embolization.
