Artery-to-Artery cerebral emboli detection with transcranial doppler: Analysis of eight cases.
We present eight cases in which intracranial arterial emboli were detected with transcranial Doppler (TCD). In all patients, the putative arterial source of emboli was demonstrated by angiography. The presumed lesion representing the source of emboli was atherosclerosis (three), radiation-induced atherosclerosis/dissection (one), fibromuscular dysplasia (one), and traumatic dissection (three). TCD was effective in detecting microemboli, localizing the potential source of emboli, and monitoring the effectiveness of treatment.
