Transcranial Doppler detection of microemboli during percutaneous transluminal coronary angioplasty.
BACKGROUND AND PURPOSE The use of percutaneous transluminal coronary angioplasty (PTCA) to treat coronary artery disease is now commonplace. The occurrence of microemboli during invasive procedures such as cardiac angiography and bypass surgery is well documented, although neurological complications are relatively uncommon. To date, no investigation has been undertaken of the frequency or natur...

متن کاملOnline automatic discrimination between solid and gaseous cerebral microemboli with the first multifrequency transcranial Doppler.
BACKGROUND AND PURPOSE The aim of this study was to assess the first multifrequency transcranial Doppler system that was specially developed to automatically detect and discriminate between solid and gaseous cerebral microemboli. METHODS The multifrequency transcranial Doppler instrumentation insonates simultaneously with 2.5 and 2.0 MHz. Differentiation between solid and gaseous microemboli ...
متن کاملAbsence of microemboli on transcranial Doppler identifies low-risk patients with asymptomatic carotid stenosis.
BACKGROUND AND PURPOSE Carotid endarterectomy clearly benefits patients with symptomatic severe stenosis (SCS), but the risk of stroke is so low for asymptomatic patients (ACS) that the number needed to treat is very high. We studied transcranial Doppler (TCD) embolus detection as a method for identifying patients at higher risk who would have a lower number needed to treat. METHODS Patients ...
متن کاملIncidence of transcranial Doppler-detected cerebral microemboli in patients referred for echocardiography.
BACKGROUND AND PURPOSE Transcranial Doppler can detect cerebral microemboli. These emboli may be a risk factor for embolic stroke. We studied the prevalence of microemboli in patients referred for echocardiography. METHODS Forty-two patients were evaluated. Patients were studied with continuous monitoring over one middle cerebral artery for 30 minutes, and the number of microemboli was record...
