Homonymous left hemianopia secondary to traumatic extracranial vertebral artery dissection

Extracranial vertebral artery dissection.

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...

Traumatic vertebral artery dissection presenting with incomplete congruous homonymous quadrantanopia

BACKGROUND To describe a rare presentation of vertebral artery dissection (VAD) as a small but congruous incomplete homonymous hemianopia demonstrating use of visual field testing in the diagnosis. CASE PRESENTATION A 30 year old woman had been unwell for 4 months with difficulty focusing, vertigo, dizziness and a feeling of falling to the right. A small but congruous right inferior homonymou...

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...

Post-traumatic vertebral artery dissection.

Correspondence: HG, e-mail: . Received 30 October 2009 and revised version accepted 15 July 2010. Competing interests: none declared. CT angiogram showed eccentric contrast in the left vertebral artery from just after its origin to the level of the C4 vertebral body suggestive of dissection (Figure 2). He was anticoagulated with enoxeparin. He walked independently when he l...
