Endovascular stent placement and coil embolization have become established options in the treatment of visceral arterial aneurysms. In this article we report the case of an 83-year-old presenting with gastrointestinal hemorrhage due to a recurrent hepatic arterial aneurysm occurring 12 years after treatment with an endovascular stent. The recurrent aneurysm had resulted from stent fracture and was successfully treated by coil embolization. To our knowledge, stent fracture complicating the endovascular treatment of a visceral artery aneurysm has not been described in the published literature. With the increasing use of metallic endoprostheses in interventional radiology, recognizing and reporting device failure are of critical importance.
血管内支架置入术和弹簧圈栓塞术已成为治疗内脏动脉瘤的既定选择。在本文中，我们报告了一例83岁患者的病例，该患者因12年前接受血管内支架治疗后复发的肝动脉瘤导致胃肠道出血。复发性动脉瘤是由支架断裂引起的，并通过弹簧圈栓塞术成功治疗。据我们所知，已发表的文献中尚未描述过内脏动脉瘤血管内治疗并发支架断裂的情况。随着金属内假体在介入放射学中的使用日益增加，识别和报告器械故障至关重要。
