Trauma to the cerebrovascular system
1Department of Radiology, University of Minnesota Hospital and Clinics, Minneapolis.
Insights
Head and neck trauma can cause cerebrovascular injuries, often missed in non-penetrating cases. Magnetic Resonance imaging offers a noninvasive method for diagnosing these vascular injuries and their neurological consequences.
Area of Science:
- Neurology
- Radiology
- Vascular Surgery
Background:
- Cerebrovascular trauma encompasses injuries like dissection, pseudoaneurysm, thrombosis, rupture, and arteriovenous fistula.
- Diagnosis of vascular injury is often considered in penetrating trauma but may be overlooked in non-penetrating trauma.
- Head and neck trauma necessitates consideration of vascular injury, particularly with neurological dysfunction.
Purpose of the Study:
- To highlight the importance of considering cerebrovascular injury in head and neck trauma.
- To discuss diagnostic modalities for cerebrovascular injuries.
- To evaluate the role of MR imaging and MR angiography in noninvasive diagnosis.
Main Methods:
- Review of diagnostic approaches for cerebrovascular injuries.
- Emphasis on the utility of Magnetic Resonance (MR) imaging and MR angiography.
- Comparison with traditional diagnostic methods like intra-arterial angiography.
Main Results:
- MR imaging and MR angiography can noninvasively diagnose cerebrovascular injuries.
- MR techniques readily detect intracranial complications such as cerebral infarction and hemorrhage.
- Intra-arterial angiography remains the gold standard but is invasive.
Conclusions:
- Cerebrovascular injury should be suspected in all head and neck trauma patients, especially those with neurological deficits.
- Noninvasive MR techniques offer a valuable alternative for diagnosing vascular injuries and their sequelae.
- Early and accurate diagnosis is crucial for managing patients with traumatic cerebrovascular injuries.
Abstract:
Trauma to the cerebrovascular system can result in vascular injuries, such as dissection, pseudoaneurysm, thrombosis, rupture, and arteriovenous fistula. Although the diagnosis of vascular injury is usually considered in all cases of penetrating trauma, it may be overlooked in patients with nonpenetrating trauma. The possibility of vascular injury should be considered in all patients with head and neck trauma, especially those patients with acute or delayed neurologic dysfunction. Although intra-arterial angiography remains the gold standard diagnostic tool, the combination of MR imaging and MR angiography may permit noninvasive diagnosis of vascular injury. Moreover, MR readily provides detection of intracranial sequelae, such as cerebral infarction and intracranial hemorrhage.
