To determine the proper approach to asymptomatic carotid bifurcation ulcerated plaque (UP), 79 patients with 91 asymptomatic UPs were identified angiographically, and a 96% follow-up was obtained with a mean duration of three years. The cumulative stroke rate by life-table analysis was 1% at seven years. Sixty-three UPs in 55 patients were classified as(More)
In 79 patients with 91 asymptomatic ulcerating lesions of the carotid bifurcation who were followed an average of 54 months, there were two strokes, one of which was preceded by a warning transient ischemic attack. These data suggest that asymptomatic type A and type B carotid ulcerating lesions do not carry a significant early risk of stroke and do not(More)
Retrospectively, 51 patients who related two or more signs or symptoms of vertebrobasilar insufficiency and possessed concomitant carotid arterial disease were identified. The patient population was separated into two groups based on the presence or absence of an angiographically visualized posterior communicating artery during selective carotid artery(More)
The ability of a B-mode, real-time, high frequency ultrasonic imager to diagnose carotid arterial disease was evaluated in 81 carotid arteries. The imager was relatively sensitive in detecting the presence of significant stenosis but was relatively insensitive in its ability to quantitate the degree of stenosis. The imager was unable to detect the presence(More)
