Recurrent Ischemic Events in Two Patients with Painless Vertebral Artery Dissection Stroke 24:598-602, McCormick,G.F.&Halbach,V.V., 1993 See this aricle in Pubmed Article Abstract Two patients were admitted with repeated transient ischemic attacks and strokes over 11 months and 1 month,respectively.Neither had a history of trauma,cervical pain,or headache.Magnetic resonance angiography failed to visualize vertebral artery dissections that were later revealed by conventional angiography.One patient's events were stopped by balloon occlusion of the vertebral artery proximal to the posterior inferior cerebellar artery branch.Magnetic resonance angiography is not yet sensitive enough to always visualize vertebral artery dissection.Vertebral artery dissection is a life-threatening condition that requires aggressive evaluation and treatment.
