Question

Neck vessel doppler in posterior circulation stroke

Answer 1

Posterior circulation stroke accounts for 20-25% (range 17-40%) of ischaemic strokes

Posterior circulation transient ischaemic attacks may include brief or minor brainstem symptoms and are more difficult to diagnose than anterior circulation ischaemia

Specialist assessment and administration of intravenous tissue plasminogen activator are delayed in posterior circulation stroke compared with anterior circulation stroke

The risk of recurrent stroke after posterior circulation stroke is at least as high as for anterior circulation stroke, and vertebrobasilar stenosis increases the risk threefold
