Extracranial vertebral artery dissection

Vertebral artery dissection (VAD) is not uncommon in the young adult population. Owing to the various clinical manifestations; the diagnosis of VAD mainly depends on imaging examinations. Ultrasound has found an increasingly wide utilization in the diagnosis of VAD because of the continuous improvement in the resolution of ultrasonic instruments and accessibility.We retrospectively collected th...

Three cases of spontaneous extracranial vertebral artery dissection.

We describe three cases of extracranial vertebral artery dissection that are unusual in both their modes of presentation and their associations with other pathologic conditions. The first patient had Marfan's syndrome and migraine; his dissection was asymptomatic and was diagnosed by chance at the time of repeat angiography following a previous internal carotid artery dissection. The second pat...

Spontaneous dissection of the carotid and vertebral arteries.

The carotid color Doppler ultrasound is usually the first imaging modality employed for the assessment of patients with cerebrovascular symptoms. The recognition of the distal stenoocclusive flow pattern is key for the detection of spontaneous dissection of the internal carotid and vertebral arteries in young patients who present cerebral ischaemic signs. We present six cases of patients whose ...

Duplex scanning in extracranial vertebral artery dissection.

Ultrasonic (duplex scanning and continuous-wave Doppler) and angiographic findings in three patients with bilateral extracranial vertebral artery dissection are reported. A pattern of ultrasonic anomalies diagnostic of dissection is described, including association of a localized increase in diameter of the artery with hemodynamic signs of stenosis or occlusion at the same level and decreased p...
