Contrast-Enhanced Ultrasound Reveals Vulnerable Carotid Plaque in Acute Stroke: A Case Report

In this case report, a patient presented with acute stroke symptoms. Contrast-enhanced ultrasound (CEUS) was instrumental in revealing the underlying cause: a ruptured carotid artery plaque. The CEUS images clearly demonstrated neovascularization within the plaque, plaque ulceration, and the presence of a floating thrombus. This accurate and detailed visualization enabled clinicians to identify the stroke mechanism as carotid artery plaque rupture leading to thrombus formation. Based on these findings, the patient received timely and appropriate treatment, including antiplatelet therapy and stent placement. This intervention resulted in a favorable prognosis for the patient. This case underscores the importance of considering vulnerable carotid artery plaque rupture as a potential cause of acute stroke. Furthermore, it highlights the utility of contrast-enhanced ultrasound as a valuable diagnostic tool for identifying the underlying cause of stroke and guiding treatment decisions.
