摘要
目的研究外伤后弥漫性脑萎缩的法医学特征,年龄与伤后脑萎缩发生间隔时间的关系,以及颅脑损伤程度与脑萎缩程度的关系。方法从性别、年龄、颅脑损伤特点、脑萎缩临床特征、脑萎缩影像学表现等方面,对25例颅脑外伤后弥漫性脑萎缩案件的法医学特征进行回顾性分析,并采用Pearson相关分析方法进行数据分析。结果外伤后弥漫性脑萎缩可发生在任何年龄段,以重型颅脑损伤为主。全部案例伤后脑萎缩发生间隔时间与年龄的相关系数(r)为0.442(P<0.05),50岁以上两者r为0.341(P>0.05),50岁以下两者r为0.904(P<0.05)。全部案例颅脑损伤程度与脑萎缩程度的r为0.579(P<0.05),重度颅脑损伤与脑萎缩程度的r为0.788(P<0.05)。结论颅脑损伤越重,脑萎缩程度越严重。重型颅脑损伤可发生不同程度弥漫性脑萎缩,轻、中型颅脑损伤后弥漫性脑萎缩以轻度、中度为主。在法医临床学鉴定实践中,遇到被鉴定人存在导致脑萎缩自身高危因素(如高血压、糖尿病等)时,需结合案件材料全面综合分析,必要时进行伤病关系分析。
Objective To study the forensic features of diffuse brain atrophy after trauma, the relationship between age and interval time of post-traumatic brain atrophy, and the relationship between the degree of craniocerebral injury and that of brain atrophy. Methods The forensic features of 25 cases of diffuse brain atrophy after craniocerebral trauma were retrospectively analyzed from aspects of gender, age, craniocerebral injury characteristics, and imaging characteristics of brain atrophy. Pearson correlation analysis was used for statistical analysis. Results Diffuse brain atrophy after trauma could occur in any age group, dominated by severe brain injury. The Pearson correlation coefficients (r) between the time interval of brain atrophy and age were 0.442 (P<0.05), 0.341 (P>0.05), and 0.904 (P<0.05) for the overall cases, the group over age 50, and the group under age 50, respectively. The correlation coefficient between the degree of brain injury and that of brain atrophy was 0.579 (P<0.05), and that between severe brain injury and brain atrophy was 0.788 (P<0.05). Conclusion The more serious the brain injury, the more severe the brain atrophy. Various degrees of diffuse brain atrophy can occur in severe craniocerebral injury, and diffuse brain atrophy is usually mild and moderate after mild and moderate craniocerebral injury. In the practice of forensic clinical identification, a comprehensive analysis should be conducted with the combination of case materials when the identified person has high risk factors leading to brain atrophy (e.g., hypertension, diabetes, etc.), plus injury and illness relationship analysis if necessary.
