Long-term ambulatory monitoring for cerebral emboli using transcranial Doppler ultrasound.
BACKGROUND AND PURPOSE Transcranial Doppler (TCD) monitoring for asymptomatic cerebral emboli is currently limited to short recordings by equipment size, restricting its clinical usefulness. We have developed a first ambulatory TCD system, evaluated it in at-risk patient groups, and used it to study the pattern of embolization in patients with symptomatic carotid stenosis. METHODS The system ...
متن کاملTranscranial Doppler Detection of Circulating Cerebral Emboli
Background: The identification of gaseous emboli using Doppler ultrasound was described as early as the 1960s. Recently it has been demonstrated that this method can also detect solid emboli such as thrombi and platelet aggregates. This may make this technology useful in a large number of patients with, or at risk of, embolic stroke. Summary of Review: Emboli appear as short-duration, high-inte...

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...
