Trauma-Induced Thoracic Stent Graft Migration and Dissecting Aneurysm Rupture.

Thoracic endovascular aortic repair (TEVAR) is widespread. We report a case of graft migration and dissecting aneurysm rupture after trauma. An 82-year-old man with a history of TEVARs for chronic type B aortic dissection had sudden dyspnea and hemoptysis after falling from a stationary bicycle. Enhanced computed tomography revealed graft migration, endoleak, and dissecting aneurysm rupture. TEVAR was repeated emergently, and he was discharged without complications. Blunt injury to the trunk of the body may cause graft migration and aortic rupture in the chronic phase after TEVAR. This report describes graft migration and rupture induced by trauma.
