Endovascular treatment of iatrogenic aortic injury after spinal surgery.

A 59-year-old female presented to our institution with paraparesis caused by medullar compression secondary to multiple myeloma. Spinal cord decompression and transpedicular spine fixation were performed. A month later, the patient complained of sudden pain in her middle back. A CT scan revealed screw impingement on the aortic wall at T8 level. A thoracic stent-graft was deployed before removing the fixation. The patient had an uneventful postoperative course, without complications during the four-year follow-up. In this case report, stent-graft placement proved to be safe and effective in avoiding bleeding during screw removal.
