An aortic arch pseudoaneurysm distal to the left common carotid artery (LCCA) was repaired endovascularly with an atrial septal defect occluder. Aortography showed complete closure of the pseudoaneurysm but delayed blood flow in the LCCA. A chimney stent was then placed into the LCCA to salvage it. Completion angiography suggested free flow in the LCCA and a minor perioccluder leak, which disappeared at 1-month follow-up. The patient was free from any symptoms related to the pseudoaneurysm at 1-year follow-up, with the atrial septal defect occluder in a satisfactory position, absence of leaking, and complete thrombosis in the pseudoaneurysm cavity.
升主动脉弓部假性动脉瘤位于左颈总动脉（LCCA）远端，采用房间隔缺损封堵器进行了血管内修复。主动脉造影显示假性动脉瘤完全封闭，但 LCCA 血流延迟。随后在 LCCA 内放置了烟囱支架以进行挽救。完成血管造影提示 LCCA 血流自由，且封堵器周围有小漏，1 个月随访时漏消失。1 年后患者无任何与假性动脉瘤相关的症状，房间隔缺损封堵器位置满意，无漏，假性动脉瘤腔内完全血栓形成。
