Use of Contrast-enhanced Carotid Ultrasonography in Preoperative Assessment for Carotid Artery Stenting
Objective: Contrast-enhanced carotid ultrasonography (CEUS) is a new technique for assessing carotid artery plaques. The present study attempted to demonstrate the association between the findings of CEUS performed prior to carotid artery stenting (CAS) and plaque debris caught during CAS. Methods: This study was conducted with 16 patients (15 men, 1 woman; mean age: 74.8 years) who had undergo...
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 کاملDetection of peripheral artery disease by duplex ultrasonography among hemodialysis patients.
BACKGROUND AND OBJECTIVES Peripheral arterial disease (PAD) is a known predictor of cardiovascular morbidity and mortality among hemodialysis patients. Although ankle-brachial BP index (ABI) is a simple and reliable test for PAD screening, its sensitivity has been suggested to decrease among dialysis patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed a cross-sectional outpat...
متن کاملDuplex sonography for carotid artery disease: an accurate technique.
Carotid arteriograms and combined real-time B-mode and Doppler sonograms were evaluated by independent observers of 101 carotid arteries in 51 consecutive patients. The results were correlated . For Duplex detection of hemodynamically significant stenosis, a specificity of 97% was obtained, sensitivity of 94%, and accuracy of 96% . The Duplex examination is an accurate method for evaluating car...
متن کاملPeripheral Artery Disease Extracranial Carotid Disease Revascularization
Extracranial carotid artery stenosis is a factor in 20% to 30% of all strokes.1,2 Revascularization strategies using surgical carotid endarterectomy (CEA) or carotid artery stenting (CAS) offer the possibility of stroke prevention by restoring flow and mitigating the risk for future plaqueassociated embolization. Numerous studies have assessed whether these procedures reduce the risk for stroke...
