Transcranial Doppler: preventing stroke during carotid endarterectomy.
Carotid endarterectomy (CEA) is more effective at preventing strokes than medical therapy alone in those patients with severe symptomatic stenosis of the internal carotid artery and this benefit persists despite a perioperative stroke/death rate of approximately 5%. Thromboembolism has been established as the underlying cause of the majority of perioperative strokes, but this could not be detec...
متن کاملTranscranial Doppler and rCBF compared in carotid endarterectomy.
In eight patients undergoing carotid endarterectomy, the mean velocity and an index of pulse amplitude in the middle cerebral artery were monitored continuously by transcranial doppler ultrasound. rCBF was measured by intracarotid injection of 133 Xenon shortly before and at the time of the carotid artery occlusion, and again a few minutes after carotid flow was reestablished. Comparison of the...
متن کاملTranscranial Doppler detected cerebral microembolism following carotid endarterectomy.
Cerebral ischaemia, the most frequent serious complication of carotid endarterectomy (CEA), usually occurs in the early postoperative period and is often the result of thromboembolism. We hypothesized that the early postoperative detection of microembolic ultrasonic signals (MES) with transcranial Doppler ultrasound (TCD) may be of value in identifying patients at risk of postoperative cerebral...
متن کاملCerebral monitoring during carotid endarterectomy by transcranial Doppler ultrasonography
PURPOSE To evaluate the efficacy and safety of cerebral monitoring by transcranial Doppler ultrasonography (TCD) for the detection of cerebral ischemia during carotid endarterectomy (CEA). METHODS From August 2004 to December 2013, 159 CEAs were performed in a tertiary hospital. All procedures were performed under general anesthesia. Intraoperative TCD was routinely used to detect cerebral is...
متن کاملDetection of middle cerebral artery emboli during carotid endarterectomy using transcranial Doppler ultrasonography.
The purpose of our study was to define the signal characteristics and clinical circumstances associated with emboli detected in the middle cerebral artery using 2-MHz pulsed transcranial Doppler ultrasound in patients undergoing carotid endarterectomy. Signals designating emboli were transients displaying harmonic qualities the signatures of which were clearly different from those of mechanical...
