Vertebral Artery Dissection with Subsequent Medullary Hemorrhaging

Medial medullary syndrome due to vertebral artery dissection.

A 61 year old woman presented at the emergency ward with a 3 day history of fluctuating vertigo and lateropulsion to the right. Clinical examination showed slurred speech, conjugated right beating horizontal nystagmus in primary gaze that increased on gaze to the right, and a right sided tongue paresis (figure A). In addition, slight motor weakness, decreased joint position, and vibration sense...

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...

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 ...

Long-term observation of lateral medullary infarction due to vertebral artery dissection assessed with multimodal neuroimaging.

A 33-year-old man presented with a lateral medullary infarction, vertigo, and nausea. At the time of hospital admission, he had Wallenberg syndrome. Although initial magnetic resonance imaging showed no abnormalities, subsequent diffusion-weighted magnetic resonance imaging showed a high-intensity area in the right lateral medulla oblongata. The right vertebral artery was shown to be dilated on...
