Abstract
Blunt thoracic aortic injury (BTAI) is fatal and requires thoracic endovascular aortic repair (TEVAR) for its optimal management. Performing TEVAR requires multidisciplinary specialists and supportive facilities. We report a case of an 89-year-old man who presented to the emergency department with blunt trauma. Whole-body computed tomography (CT) revealed grade II aortic injury with disrupted blood flow to the left kidney. Sudden paralysis of the left lower extremity and distal progression of the aortic dissection occurred. However, TEVAR could not be performed immediately. Therefore, an external shunt from the right common femoral artery to the left lower extremity was created with angioplasty, superior mesenteric artery (SMA) stenting, and celiac artery (CA) balloon dilatation. The patient's condition stabilized, and he was transferred to a hospital where TEVAR was performed. Selective arterial catheterization (SAC) for treating intraperitoneal organ malperfusion caused by BTAI may be an effective bridging therapy for TEVAR.
