A patient who had previously undergone retrosternal gastric tube reconstruction for esophageal cancer presented with an aortic arch aneurysm. The patient was treated with endovascular stent-graft placement without median sternotomy, followed by revascularization of the brachiocephalic trunk using percutaneous in situ graft fenestration. A 9-month follow-up examination revealed marked regression of the aneurysm with patency of the stent-graft, without any complications. This in situ fenestration technique may extend the limits of thoracic endovascular therapy for patients who are unsuitable for sternotomy or aortic side-clamping.
一位因食管癌而行胸骨后胃管重建的患者出现主动脉弓动脉瘤。该患者接受了血管内支架置入术治疗，未行正中胸骨切开术，随后采用经皮原位移植开窗术对头臂干进行血运重建。9 个月的随访检查显示，动脉瘤明显缩小，支架通畅，无任何并发症。这种原位开窗技术可能为不适合正中开胸或主动脉侧壁钳夹的患者扩展了胸主动脉腔内治疗的适应证。
