Insights
Dissecting internal carotid arteries during necropsy of head trauma cases is recommended. Injuries to these vessels can clarify the cause of death, indicating cerebral hypoxia, not just blood loss.
Area of Science:
- Forensic Pathology
- Neuroanatomy
- Traumatology
Context:
- Craniocerebral trauma is a leading cause of death.
- The intraosseous course of the internal carotid arteries is rarely examined in fatal cases.
- Accurate determination of cause of death in head trauma is critical.
Purpose:
- To recommend the dissection of the intraosseous internal carotid arteries in necropsies of fatal craniocerebral trauma.
- To present suitable preparation techniques for this dissection.
- To provide a pathophysiological interpretation of findings.
Summary:
- Dissection of the intraosseous internal carotid arteries in fatal craniocerebral trauma cases is advised.
- Detected injuries to these vessels aid in determining the cause of death.
- Rupture of the intraosseous internal carotid artery leads to lethal cerebral hypoxia, not hemorrhagic shock.
Impact:
- Improved accuracy in forensic investigations of head trauma.
- Enhanced understanding of the mechanisms of death in craniocerebral injuries.
- Potential for refined medico-legal conclusions in trauma cases.
Abstract:
At necropsy of fatal cases due to craniocerebral trauma it is highly recommended that the intraosseous course of the internal carotid arteries are dissected, as detected injuries of these vessels may allow improved conclusions concerning the course of death. Suitable preparation techniques are presented. On the basis of the anatomical and physiological situation as well as pathophysiological considerations the acute lethal outcome of traumatic rupture of the intraosseous part of these arteries is not to be interpreted as death by hemorrhagic/hypovolemic shock but rather as lethal cerebral hypoxia subsequent to a rapidly developing insufficiency of the brain circulation.
