Comments, Opinions and Reviews Carotid Artery Noninvasive Testing is Being Overused
The most frequent tests done in the evaluation of patients with potential cerebrovascular disease are Oculoplethysmography (OPG) and Imaging procedures. These procedures are useful in the evaluation of asymptomatic carotid bruits and may be helpful in evaluating patients with nonhemispheric symptoms. However, there is no reasonable indication for the use of these noninvasive procedures on patie...
متن کاملLimitations of noninvasive testing in assessing the "occluded" carotid artery.
Over a 3 year period eight cases of atherosclerotic pseudoocclusion were detected by carotid angiography. The diagnosis was based on the detection of a thin, delayed antegrade trickle of contrast medium distal to an area of extreme stenosis. In six of these cases both direct and indirect noninvasive tests were interpreted as showing total occlusion. In one case these tests were thought to demon...
متن کاملPreoperative diagnosis of carotid artery stenosis: accuracy of noninvasive testing.
BACKGROUND AND PURPOSE Carotid endarterectomy has been shown to be beneficial in symptomatic patients with a severe stenosis (70% to 99%) of the internal carotid artery (ICA). Digital subtraction angiography (DSA) is the standard of reference in the diagnosis of carotid artery stenosis but has a relatively high complication rate. In a diagnostic study we investigated the accuracy of noninvasive...
متن کاملNoninvasive monitoring of internal carotid artery dissection.
BACKGROUND AND PURPOSE Internal carotid artery dissection has increasingly been reported as a cause of transient ischemic attack or stroke. However, scarce data exist on the natural history of the arterial lesions and the temporal profile of recanalization. METHODS We followed 48 patients with 50 angiographically confirmed internal carotid artery dissections by sequential duplex Doppler studi...
متن کاملNoninvasive testing for carotid artery stenosis: I. Prospective analysis of three methods.
Oculoplethysmography-carotid phonoangiography and periorbital directional Doppler sonography are two techniques widely used in the noninvasive evaluation of possible carotid artery disease. Recent advances with sonographic Doppler devices now permit measurement of blood velocities in the extracranial carotid arteries by direct scanning with a color coded Doppler imaging system. A prospective st...
