[Traumatic Disruption of the Aortic Root and the Ascending Aorta with Multisystem Trauma;Report of a Case].

We report a case of traumatic disruption of the aortic root with multisystem trauma. A 45-year-old male was suffered from multiple injuries including subarachnoid hemorrhage, lung contusion, retroperitoneal hematoma and femoral bone fracture caused by a traffic accident. He had a history of 3 cardiac surgeries including repair of atrioventricular septal defect and mitral valve replacement using a mechanical valve. Contrast-enhanced computed tomography (CT) revealed leakage of the contrast medium from the aortic root and a filling defect on the right coronary artery. Because of hemorrhagic complications, emergency operation was avoided. He was operated 2 days after the trauma. Laceration of the left-coronary sinus and the non-coronary sinus was observed. Bentall operation was performed and the right coronary artery( RCA) was bypassed with a saphenous vein graft. He was treated with open fixation of the right femur 14 days after the operation and was discharged 58 days after the 1st operation.
