Simultaneous Monitoring of the Middle Cerebral and Basilar Arteries to Detect Right-to-Left Shunts Using Transcranial Doppler by Agitated Saline Administration
Abstract:Transcranial Doppler (TCD) is an easy, non-invasive, and real-time monitoring device for detecting right-to-left shunts (RLS). Nonetheless, it has limited benefits in patients with poor temporal windows. Therefore, we aimed to investigate whether the basilar artery (BA) window was as effective as the middle cerebral artery (MCA) in detecting RLS during TCD monitoring. Overall, we enrolled 344 patients with stroke, transient ischemic attack, headache, or dizziness. MCA and BA were monitored using a modified hea… Show more
