About this trial

Carotid artery stenting (CAS) prevents stroke but carries risks of perioperative cerebral embolism. Transcranial Doppler (TCD) ultrasound can detect microemboli during CAS and may offer therapeutic benefits through ultrasound-enhanced thrombolysis. Trials like SONOBUSTER and SONOBIRDIE suggest TCD reduces new brain infarctions during carotid procedures. The TCD-ICAS trial will investigate whether TCD application during and after CAS reduces perioperative cerebral emboli and improves outcomes.
