Magnetic Resonance Angiography Source Images of Vertebral-artery Dissection

A 62-year-old man was admitted to our hospital with a brain infarction in the right medulla. On the first day, he was diagnosed with a vertebral artery dissection, based on the findings from conventional angiography, which showed an irregular stenosis associated with a pseudoaneurysm of the right vertebral artery (Picture 1).

Vertebral Artery Dissection

Background and Purpose: In this study we analyzed the value of ultrasound examination for diagnosis of vertebral artery dissection. Methods: The vertebrobasilar arterial system was assessed in 14 patients using transcranial and extracranial pulsed-wave Doppler and duplex sonography. Results: The dissections were verified by angiography (in 1 patient), magnetic resonance imaging (in 5), or both ...
