Insights
Traumatic arterial dissection can cause stroke in young adults. Prompt diagnosis and intensive care are crucial to prevent permanent neurological damage from these craniocervical injuries.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Cerebral artery dissection is a significant cause of stroke in patients under 45.
- Craniocervical trauma, particularly from motor vehicle accidents, can lead to arterial dissection.
- Symptoms like unilateral headache and cranial nerve palsy warrant consideration of arterial dissection.
Observation:
- Intramural hematoma and vessel morphologic changes (stenosis, pseudoaneurysm) are key diagnostic indicators.
- CT/CTA is used for acute phase diagnosis, while MRI/MRA is preferred for the subacute phase.
- Delayed cerebral infarction can occur secondary to traumatic arterial dissection.
Findings:
- Two cases of delayed cerebral infarction due to traumatic extra- and intradural arterial dissection after motor vehicle accidents are presented.
- Early diagnosis and management are critical for patient outcomes.
- Intensive care unit monitoring is recommended for these patients.
Implications:
- Timely diagnosis and intervention in traumatic arterial dissection can prevent long-term neurological deficits.
- Understanding the diagnostic modalities (CT/CTA, MRI/MRA) is essential for effective management.
- Anticoagulation or antiplatelet therapy is the standard acute treatment for arterial dissection.
Abstract:
Dissection of extra- and intradural arteries is a common cause of cerebral insult in younger patients (<45 years). In patients with corresponding craniocervical injury and symptoms (carotidynie, ipsilateral headache, partial Horner syndrome, cranial nerve palsy) arterial dissection is always to be considered. Essential in diagnosing arterial dissection is the verification of the intramural hematoma and morphologic changes in the vessel (stenosis, pseudoaneurysm) by means of CT/CTA (acute phase) or MRI/MRA (subacute phase). These patients need to be monitored in an intensive care unit setting. The acute therapy includes anticoagulation or inhibition of thrombocyte aggregation. We present two cases with delayed cerebral infarction due to traumatic extra- and intradural arterial dissection after a motor vehicle accident. To perform primary diagnostic quickly and adequately may avoid permanent neurological deficit in these patients.
