外伤迟发性颅内出血死亡案例研究

通过对一例外伤迟发性颅内出血死亡案例分析,探讨了外伤迟发性颅内出血的临床表现、诊断依据、病理组织学特点及相关法医检验的应对要素。研究发现,外伤性迟发性颅内出血是外伤后早期未发生出血、经数日或数周突发出血,引发伤者出现颅内压升高症状及体征,经CT复查而发现的一种延迟性出血。其成因为外伤时外力作用致脑实质多发小软化灶,持续地损伤脑内血管,因诱因导致血压的突然升高或附近组织急剧变化的抵抗而发生出血。所以,对于外伤性迟发性颅内出血,需结合调查,全面分析其伤后医疗病历、CT检查回报以及尸检病理组织学所见等,综合判断。以避免引起伤者、致伤者、医院甚至办案单位等多方纠纷。

A Case Study on Delayed Traumatic Intracranial Hemorrhage Death

Through a case analysis of delayed traumatic intracranial hemorrhage death, this article discusses the clinical manifestations, diagnosis bases, histopathological features of intracranial hemorrhage and key factors of dealing with relevant forensic examinations. Studies show that delayed traumatic intracranial hemorrhage is a type of delayed intracranial bleeding that suddenly occurs in several days or weeks after the initial trauma. It can result in the signs and symptoms of increased intracranial pressure, which is often diagnosed by CT reexamination. Its attributing reason is that exogenic action makes brain parenchyma produce multiple small softened lesions, which continuously damage brain vessels, and ultimately lead to bleeding upon a surge in blood pressure or rapid changes of nearby tissue. Therefore, the delayed traumatic intracranial hemorrhage should be judged by investigations, comprehensive analyses of their post-injury medical records, results of CT examination and pathological histology of corps so as to avoid multi-party disputes among the injured, the people causing injury, hospitals and even the law-enforcement agencies themselves.
