Objectives: The diameters of the vertebral arteries (VAs) are very often unequal. Therefore, this study investigated if unequal VA flow contributes to the development of basilar artery (BA) curvature ...

A middle aged patient presented with acute ischemic stroke due to basilar artery occlusion. The patient clinically deteriorated despite intravenous thrombolysis and was referred for mechanical ...

Figure 4. Digital subtraction angiography with early and late phase demonstrating (A) left subclavian artery occlusion with (B) retrograde vertebral filling of proximal subclavian artery.

Proximal left subclavian arterial occlusion and retrograde flow in the LIMA graft and the left vertebral artery were convincing evidence of coronary-subclavian-vertebral steal syndrome. After coronary ...
