Each boy's initial MRA was not interpreted as delineating occlusive lesions to explain the posterior circulation infarcts visualized on computed tomography and magnetic resonance imaging scans. However, subsequent MRAs were suspicious for vertebral artery dissection, which was confirmed by TFA. Both ...
Because of the difficulty in physical examination and CFD in diagnosing vertebral arterial injuries, CTA and MRA will be the diagnostic modalities that identify the majority of abnormalities. Both imaging techniques allow visualization of all segments of the vertebral artery without obstructed shadowing fr...
Women have a 3 times greater risk of verterbral artery dissection than men. Whereas gradual narrowing and a sudden blockage with a clot (artherothrombotic) is the main cause of strokes in the elderly, vertebral artery dissection is the main reason for people under 45 years of age with an a...
