['To assess if Doppler microembolic signals (MES) associated with > or = 60% symptomatic extracranial carotid stenosis may predict ischemic recurrences before endarterectomy or angioplasty.', 'All patients with > or = 60% carotid stenosis with symptoms in the preceding 2 months were prospectively considered. MES were identified using current criteria. All patients were followed-up until endarterectomy or angioplasty.', 'We studied 50 patients, at a median of 7 days from their last symptom. Twenty patients showed MES (40.0%); median embolus rate was 4/h. During a median follow-up of 19 days 7 patients had recurrences (transient monocular blindness = 2; TIAs=4; stroke=1); 6 of them had shown MES. The association between recurrences and MES was significant (P=0.012).'] Do doppler microembolic signals predict ischemic recurrences in symptomatic carotid stenosis?
