Subarachnoid haemorrhage due to upper cervical trauma
Journal of Clinical Pathology
|December 1, 1983
Summary
Trauma to the upper cervical region can cause fatal subarachnoid hemorrhage. This may occur when a damaged vertebral artery tracks blood into the subarachnoid space, leading to rapid death.
Area of Science:
- Neurology
- Trauma Surgery
- Forensic Pathology
Background:
- Subarachnoid hemorrhage is a critical condition often associated with aneurysms or arteriovenous malformations.
- The role of direct cervical trauma in causing subarachnoid hemorrhage is less understood.
Observation:
- Seventeen cases of fatal subarachnoid hemorrhage linked to upper cervical region injury were analyzed.
- Most patients had alcohol intoxication and sustained injuries during altercations.
- Death was typically rapid, though not always immediate.
Findings:
- Upper cervical trauma is proposed as a cause of subarachnoid hemorrhage.
- A potential mechanism involves blood tracking into the subarachnoid space from a damaged vertebral artery or its branches.
Implications:
- This finding suggests a direct link between cervical spine trauma and subarachnoid hemorrhage.
- Understanding this mechanism is crucial for diagnosing and treating such injuries.
- Forensic investigations should consider cervical trauma in cases of unexplained rapid death.
