Intraoperative carotid artery duplex scanning in a modern series of 650 consecutive primary endarterectomy procedures.
PURPOSE Thromboembolic complications after carotid endarterectomy are frequently associated with technical defects. We analyzed the effect of intraoperative duplex scanning in detection of significant but clinically unsuspected technical defects and residual common carotid artery (CCA) disease as a potential source of postoperative transitory ischemic attack (TIA) and stroke. METHODS From Apr...
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 کاملEarly haemodynamic changes in the ophthalmic artery, siphon and intracranial arteries after carotid endarterectomy estimated by transcranial Doppler and duplex scanning.
OBJECTIVES To study early haemodynamic changes in connection with carotid endarterectomy (CE). METHODS Sixty-three consecutive patients, average age 64, with symptomatic stenosis in the internal carotid artery (ICA) > or = 70% were examined clinically and by transcranial Doppler (TCD) 1 day before and within 48 h after CE. Duplex scanning of extracranial vessels was performed within 1 week af...
متن کاملEDITORIAL: Intraoperative Duplex Imaging of Carotid Endarterectomy
Improved outcome following carotid endarterectomy becoming the favoured technique for completion imis dependent upon low surgical morbidity and moraging, because it provides both anatomical and haemotality rates. Guidelines for performing carotid enddynamic information without increasing the risk of arterectomy recommend that surgeons should have a the procedure. documented complication rate of...
متن کاملDuplex scanning exploration of the ophthalmic artery for the detection of the hemodynamically significant ICA stenosis.
BACKGROUND AND PURPOSE The North American and the European Carotid Endarterectomy Trials demonstrated a significant benefit of surgery in preventing stroke for patients with symptomatic hemodynamically significant internal carotid artery (ICA) stenosis. Because the 3 angiographic methods of measuring carotid stenosis provide discrepant results, the indication for surgery depends on the method u...
