Abstract

Traumatic rupture of the thoracic aorta is the second most common cause of death from motor vehicle accidents after head injury. About 85% of these patients do not survive to reach the hospital. The most common mechanism for this is deceleration injury, as occurs in a high speed motor vehicle accident. The aortic isthmus is the site of disruption for about 95% of all blunt thoracic aortic injuries. Another mechanism is crush injury which causes compression of the aorta between the displaced sternal body or manubrium and the thoracic vertebral column. These forces tear the inner layer of the aortic wall at an unusual location. We report here on a case of aortic arch dissection where the injury clearly occurred due to a crush injury and not because of deceleration. The surgical repair was delayed for 10 days after administering intensive medical therapy. The ascending aorta and aortic arch were replaced with an artificial graft with the patient under circulatory arrest and cerebral protection.

흉부 대동맥의 외상성 파열은 두부 손상 다음으로 흔한 교통사고의 사망원인으로 약 85%의 환자가 병원 도착 전에 사망한다. 가장 흔한 기전은 고속의 차량이 충돌 등으로 인한 급작스런 감속에 의해 발생되며 대동맥 협부가 전체 대동맥 손상의 95%에 해당된다. 또 다른 기전으로는 흉부 압박 손상에 의해 골절되어 전위된 흉골병과 흉부 척추 사이에 대동맥이 끼이면서 나타날 수 있는데 이로 인해 흔하지 않은 위치의 대동맥벽의 내막이 파열된다. 저자들은 감속사고가 아닌 흉부 압박에 의해 대동맥궁이 파열되어 박리된 증례에 대해 집중적인 내과 치료 후에 지연 수술로 완전 순환정지 하에 뇌보호를 시행하면서 상행 대동맥의 일부와 대동맥궁을 인조혈관으로 치환하였기에 보고하는 바이다.
