A hemodynamic as opposed to an embolic origin of vertebrobasilar ischemia may be suspected when symptoms are brief and triggered by changes in the position of the head or neck. It may be difficult, and not without risk, to reproduce the symptoms and to prove the short-lived hemodynamic changes during angiography. If transcranial Doppler sonography (TCD) could detect these changes, it would be useful as a noninvasive screening method to select patients for further diagnostic evaluation.
