A study was conducted from 1 July 1991 to 30 June 1994 to determine the incidence of blunt traumatic rupture of the thoracic aorta (RTA) in a defined area of inner-metropolitan Sydney. The study group consisted of 30 subjects with RTA following falls, rail or road accidents, who were taken by ambulance to the regional trauma centre or directly to forensic pathology. The incidence of RTA in the resident population of 330,000 was in the range 20-30/10(6)/year. There was one survivor in the series, with 24 scene deaths and five deaths en route to hospital. Road accidents were responsible for 57% of incidents. RTA was found in 36% of the fatalities that occurred as a result of car and motorbike accidents. This was 5 times more common than that observed in pedestrian deaths (P < 0.005). Twenty-seven subjects (90%) had at least one co-existent critical or lethal injury. Outcome may be improved by increasing awareness of the high prevalence of RTA in shocked car- and motor-bike-accident victims and stressing the importance of rapid transport of such cases to an appropriate hospital.
一项研究于1991年7月1日至1994年6月30日开展，以确定悉尼内城区特定区域胸主动脉钝性创伤破裂（RTA）的发病率。研究组由30名因跌倒、铁路或道路事故导致RTA的受试者组成，他们由救护车送往区域创伤中心或直接送往法医病理学部门。在33万常住人口中，RTA的发病率为每年20 - 30/10⁶。该系列中有1名幸存者，24人在现场死亡，5人在送往医院途中死亡。道路事故占事件的57%。在汽车和摩托车事故导致的死亡中，36%发现有RTA。这比在行人死亡中观察到的情况常见5倍（P < 0.005）。27名受试者（90%）至少有一种并存的严重或致命伤。提高对休克的汽车和摩托车事故受害者中RTA高患病率的认识，并强调将此类病例迅速转运至合适医院的重要性，可能会改善预后。
