Pseudoaneurysm of the hepatic arteries is uncommon following liver transplantation and is usually iatrogenic. We describe a case of balloon angioplasty of a left hepatic artery stenosis complicated by an iatrogenic pseudoaneurysm. Resolution of the stenosis and the pseudoaneurysm was achieved through a combination of a bare stent and a balloon-expandable covered stent. The completion angiogram demonstrated excellent appearance of the patent hepatic arteries with exclusion of the pseudoaneurysm. No surgery was required. The graft and the patient did well for the following 6 months. Doppler ultrasound examination at 2 and 6 months postintervention revealed patent hepatic arteries and no evidence of the pseudoaneurysm.
肝动脉假性动脉瘤在肝移植后并不常见，通常是医源性的。我们描述了一例左肝动脉狭窄球囊血管成形术并发医源性假性动脉瘤的病例。通过裸支架和球囊扩张型覆膜支架联合使用，实现了狭窄和假性动脉瘤的消退。最终血管造影显示肝动脉通畅，假性动脉瘤被排除，外观良好。无需手术。在接下来的6个月里，移植物和患者情况良好。干预后2个月和6个月的多普勒超声检查显示肝动脉通畅，无假性动脉瘤迹象。
