Acute subdural hemorrhage is typically associated with a history of head trauma, and as such it is a finding with significant potential medicolegal consequences. In this article, 37 adult and post-infantile pediatric sudden death autopsy cases with small volume ("thin film" or "smear") acute subdural hemorrhage are presented-in which there is either no further evidence of head trauma or only features of minor head injury. The possible underlying pathophysiological mechanisms are explored, and it is concluded that a common thread in many of these cases is likely to have been cranial venous hypertension at around the time of death. These findings may have implications in instances where small volume subdural hemorrhage is identified in the absence of other evidence of significant head injury.
急性硬膜下出血通常与头部外伤史相关，因此这一发现具有重大潜在的法医学后果。本文报告了37例成人及婴儿期后儿童猝死尸检病例，这些病例存在少量（“薄膜状”或“涂片状”）急性硬膜下出血，其中要么没有进一步的头部外伤证据，要么仅有轻度头部损伤特征。探讨了可能的潜在病理生理机制，并得出结论，许多此类病例的一个共同线索可能是死亡前后的颅内静脉高压。这些发现可能对在无其他重大头部损伤证据的情况下发现少量硬膜下出血的情况具有启示意义。
