The aim of the present study was to explore the prevalence of acute cerebrovascular symptoms temporally related to carotid Doppler examination (DEx), in order to increase the awareness and recording of such events and to discuss possible mechanisms. All adult patients who complained of acute onset neurologic symptoms during or shortly after a carotid DEx, between 01/2003 and 12/2011 in the University Hospital of Lausanne were prospectively collected. We identified four consecutive patients with acute onset neurologic symptoms during or shortly after a carotid DEx among approximately 13,500 patients who underwent carotid DEx in our facility during the nine-year period (0.015% of all examined carotids). Clinical data, imaging reports and CTA (CT angiography) or/and ultrasound images are presented for each patient. Ischemic cerebrovascular events during or immediately after cervical Doppler could be due to chance or to several physical factors. They should be promptly recognized by Doppler personnel and properly treated, but do not put into question the overwhelming benefits of Doppler in cerebrovascular patients.
