BACKGROUND: Cervical carotid dissection is more common in extracranical vessel: internal carotid artery dissection (ICAD)is typical, vertebral artery dissection is uncommon, common carotid artery dissection (CCAD) is rare and even a morerare cause of ischemic stroke. Cervical artery dissections account up to 20-25% of ischemic strokes in young patients.Isolated and spontaneous common carotid artery dissection without aortic damage is unique. Indeed in the Literature 8cases were identified. MRI and CTA were the most commonly used for diagnosis and follow-up.
CASE REPORT: A 67-year-old came to our observation reporting burning pain in the right latero-cervical region in supineposition, irradiated in the temporal region and recurrent episodes of migraine with aura (scintillating scotoma), in thelast 3 months. The last Doppler Ultrasound control, performed after the onset of symptoms, showed an highlighted dis-section wall with double lumen at the origin of the bulb and the internal carotid artery on the right. Aortic arch arte-riography confirmed the diagnosis. The patient underwent surgery (longitudinal arteriotomy, removing four miointimalflaps, fastening the distal common carotid artery with 3 Kunlin’s points).
RESULTS: Any neurological or vascular problems after surgery were noticed.
DISCUSSION AND COMMENTS:The pathogenesis can be related to a combination of an intrinsic weakness in the arteri-al wall and an external trigger. The diagnosis of CAD is made with MRI (78.0%), conventional angiography (31.1%),CTA (14.7%), and ultrasound (11.3%).CONCLUSION: No evidence-based guidelines exists for treatment of CCAD. In our patient surgical CEA treatment wasthe optimal solution.
