摘要
目的分析道路交通事故死亡案例中胸部主动脉损伤的特点,为法医学鉴定提供数据参考。方法从性别、年龄、交通方式、胸部主动脉损伤情况等方面对存在胸部主动脉损伤的27例交通事故死亡案例资料进行分析。结果交通事故主动脉损伤案例中,男性明显多于女性,31~70岁年龄段占74.1%;交通方式以摩托车多见,其次为电动车,多与货车发生交通事故;多伴有肋骨骨折以及肺损伤;胸部主动脉损伤好发于升主动脉处,其次为主动脉弓和胸主动脉。升主动脉损伤好发于距离主动脉瓣0~<1.6 cm内,而≥2.6 cm处较少见,主动脉瓣膜损伤好发位置依次为前半月瓣、右后半月瓣、左后半月瓣。63.0%的案例发生主动脉破裂,另外37.0%仅发生主动脉内膜、中膜裂伤。少数死者伴有主动脉病变。结论交通事故所形成的作用力较大,胸腹部损伤容易造成升主动脉近心端损伤。法医在对交通事故死亡案例进行法医学鉴定时应仔细查验主动脉损伤情况,根据损伤及主动脉病变情况、程度等综合判断伤病关系。
Objective To analyze the characteristics of thoracic aorta injury in road traffic accidents,to provide data reference for forensic identification.Methods The data of 27 traffic accident death cases with thoracic aorta injury were analyzed according to relevant parameters including sex,age,mode of transportation,and thoracic aorta injury.Results Aortic injury in traffic accidents was significantly more in males than females,and 74.1%cases were in the age range of 31-70 years.The most common mode of transportation was the motorcycle,followed by electric bike,most of which crashed with trucks.Most cases were accompanied by rib fractures and lung injuries.Thoracic aorta injury was the most common in ascending aorta,followed by aortic arch and thoracic aorta.Ascending aorta injury was most likely to occur in the range of 0-<1.6 cm from the aortic valve,while it was rare over 2.6 cm.Taking the aortic valve as the reference,the most common locations of injury were the anterior semilunar valve,followed by the right posterior semilunar valve and the left posterior semilunar valve.Thoracic aortic rupture occurred in 63.0%cases,and intima and media lacerations only occurred in 37.0%cases.A few deceased had aortic diseases.Conclusion The proximal part of the ascending aorta is prone to be injured because of the large external force of traffic accidents.The medical examiner should carefully examine the aortic injury in traffic accident deaths,and evaluate the relationship between the injury and the disease according to the condition and degree of aortic injury.
