Abstract:
Vascular injuries after spine surgery may result in acute life-threatening hemorrhage, chronic arteriovenous fistula, or pseudoaneurysm formation. The interval between injury and rupture may range from seconds to years, and accordingly, a high index of suspicion is needed to make the diagnosis. Although acute and delayed vascular injury caused by placement of posterior pedicle screw fixation has been reported, the potential for large vessel disruption during posterior pedicle screw removal has been rarely reported. This case report concerns a 50-year-old man who developed an descending thoracic aortic pseudoaneurysm after posterior pedicle screw removal, diagnosed by chest computed tomography(CT) scan and transesophageal echocardiography(TEE).
