Abstract
Three-dimensional ultrasonography is a significant novelty in neurosonology as it
offers the possibility of an even more successful evaluation of atherosclerotic stenoses of
the carotid trunk than previous ultrasonographic investigations. In 37 patients with
signs of transitory ischemic attack and in 5 patients with reversible ischemic neurologic
deficit we compared the findings of three-dimensional ultrasonography of carotid arteries
on the neck with those of three-dimensional CT angiography. In 20 of these patients
in which carotid thrombendarterectomy had been carried out, the findings of both diagnostic
methods were also compared with the angiographic and operative findings. In 2
out of the total of 42 compared findings of three-dimensional ultrasonography, three-dimensional
CT angiography and angiography of the carotid trunk, we assessed a difference
in the evaluation of the degree of carotid stenosis while all other findings were in
accordance as regards the evaluation of the degree of stenosis and plaque analysis. Of
20 operative findings, one showed insignificant deviations from the findings of both diagnostic
methods. It is our opinion that three-dimensional ultrasonography is a reliable
diagnostic method in evaluating atherosclerotic stenoses of carotid arteries. Every subtotal
stenosis or internal carotid artery occlusion established by three-dimensional ultrasonography
must be compared with three-dimensional CT angiography or classic
angiography due to the objective possibility of false ultrasonographic interpretation and
the significance of carotid thrombendarterectomy.
