背景：椎弓根螺钉器械手术可导致主动脉假性动脉瘤的发展，这是一种罕见但潜在的严重并发症；因此，这项工作的目的是描述手术后椎弓根螺钉严重迁移引起的胸主动脉假性动脉瘤的情况。
方法：我们在此报告一名患者，该患者在胸椎固定手术后接受了降主动脉假性动脉瘤的血管内修复术。最初通过右股动脉插入28-80毫米覆膜支架，术中主动脉造影显示造影剂少量外渗。随后，再植入28-140mm覆膜支架.患者在8年随访期间恢复良好。
结论：脊柱手术引起的血管并发症严重且罕见，需要早期诊断和干预。
BACKGROUND: Pedicle screw instrument surgeries can result in the development of aortic pseudoaneurysm, which is a rare yet potentially severe complication; therefore, the purpose of this work is to describe the case of pseudoaneurysm of the thoracic aorta caused by the severe migration of a pedicle screw after surgery.
METHODS: We herein report a patient who underwent endovascular repair for the pseudoaneurysm of the descending thoracic aorta following thoracic vertebral fixation surgery. A 28-80 mm covered stent was initially inserted through the right femoral artery, and intraoperative aortography revealed a minor extravasation of contrast material. Subsequently, an additional 28-140 mm covered stent was implanted. The patient recovered well during the 8-year follow-up period.
CONCLUSIONS: Vascular complications resulting from spinal surgery are severe and rare, necessitating early diagnosis and intervention.
