The concept of acute arterial pseudo-occlusion (PO) defines a flow artifact in CT angiography (CTA) or digital subtraction angiography (DSA) that gives the appearance of occlusion at a certain level when the vessel is, in fact, permeable and the occlusion is localized at a more distal segment.[1] This finding is associated with a slow flow of unopacified blood due to the lack of drainage pathways.[2]
PO has been described in recent years at the extracranial internal carotid artery (ICA) by thrombi located mainly in the intracranial segment, appearing in up to 46% of these patients.[3] However, there are no previous reports of arterial PO in the posterior circulation.
A 56-year-old woman presented with new-onset gait unsteadiness, vomits, and a decreased level of consciousness, requiring orotracheal intubation. Unenhanced brain CT revealed a proximal hyperdense basilar artery and CTA showed an unopacified left vertebral artery that is filled distally (V4 and V3 segments) in a retrograde manner, suggesting proximal occlusion [Figure 1a and b]...
