Hybrid approach for removal of an errant intra-vascular pedicle spinal fixation screw in the thoracic aorta
Late presentation of aortic injuries secondary to internal fixation hardware is uncommon and generally associated with pseudoaneurysm formation. We herein present a case of transmural migration of a pedicle screw into the descending thoracic aorta, which was revealed incidentally by computed tomography scan after almost 4 years of hardware implantation. Approximately 75% of the pedicle screw was exposed to the bloodstream, and was successfully removed using endovascular segmental exclusion to avoid aortic cross-clamping and an open approach via left thoracotomy. This case illustrates the successful repair of an iatrogenic aortic injury using a hybrid technique.
