Duplex scanning in extracranial vertebral artery dissection.
Ultrasonic (duplex scanning and continuous-wave Doppler) and angiographic findings in three patients with bilateral extracranial vertebral artery dissection are reported. A pattern of ultrasonic anomalies diagnostic of dissection is described, including association of a localized increase in diameter of the artery with hemodynamic signs of stenosis or occlusion at the same level and decreased p...
متن کاملValue of the Non-Invasive Cerebrovascular Laboratory in Diagnosis of Extracranial Carotid Artery Disease
Non-invasive vascular testing has proven to be an effective means of identifying patients with significant extracranial carotid artery disease. Such tests can yield valuable physiologic data in patients with TIAs and can identify patients with soft signs who may have significant carotid artery disease and who may be candidates for angiography. It may be an effective means of reducing the number...
متن کاملUltrasound evaluation of extracranial carotid artery lesions in Parkinsonian patients.
The purpose of this investigation was to determine the atherosclerotic changes in patients with vascular parkinsonism and in patients with idiopathic Parkinson's disease, in order to evaluate the possible influence of the extracranial pathology of carotid arteries in developing lacunar cerebral infarcts. Degree of stenosis and plaque morphology of the extracranial part of carotids in both group...
متن کاملUltrasonic duplex scanning for disease of the carotid artery.
The duplex ultrasonic scanner combines real-time B-mode imaging with a single-gate, variable-range pulsed Doppler. The detection and categorization of the severity of carotid artery atherosclerosis is achieved by performing spectral analysis of the pulsed Doppler velocity signal obtained from vessels of interest. Using this technique, 750 patients with suspected extracranial carotid artery dise...
متن کاملExtracranial carotid artery stenosis.
BACKGROUND Carotid endarterectomy is the most common surgical procedure used to treat stenosis of the extracranial precerebral carotid artery. Data from several randomized controlled trials are available to help guide its use in specific patient subgroups. Carotid angioplasty with stenting is also being performed, and clinical trials comparing this procedure with carotid endarterectomy are in p...
