Contrast-Enhanced Ultrasound: A Powerful Tool for Detecting Carotid Artery Plaque Rupture and Stroke

Carotid artery plaque rupture leading to stroke is a frequently encountered emergency in neurology, typically diagnosed using CTA and DSA examinations. However, we present a case where contrast-enhanced ultrasound proved to be a valuable tool in identifying the cause of stroke as the rupture of a vulnerable plaque in the carotid artery, resulting in the formation of a floating thrombus. This rare application of contrast-enhanced ultrasound highlights its practicality in detecting carotid artery plaque rupture leading to stroke. Not only is contrast-enhanced ultrasound convenient and non-radiating, but it also offers the advantages of being non-nephrotoxic, providing real-time imaging, and can be performed at the patient's bedside.
