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.
