Internal carotid artery dissection is an increasingly recognized cause of
cerebrovascular events. The diagnosis is conventionally established on the
basis of characteristic clinical symptoms and arteriographic findings.
However, the presence of characteristic hemodynamic features detected by
ultrasound may already suggest the diagnosis, even in atypical cases. This
is demonstrated in 16 (76%) of 22 patients with internal carotid artery
dissection. An intense systolic low-frequency Doppler signal of alternating
flow direction accessible in the neck, either along the extent of a luminal
tapering stenosis or proximal to a severe obstruction at the skullbase,
indicated this diagnosis. Resolution or decreasing stenosis may similarly
be diagnosed noninvasively, as shown by results from subsequent
arteriograms in 14 patients (64%). This occurred suddenly during sequential
follow-up between 2 days and 30 weeks (mean, 6 weeks) after the diagnosis
was made.
