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

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

Background: Carotid artery plaque rupture leading to stroke is a common neurological emergency, often diagnosed using CTA and DSA. We present a rare case where contrast-enhanced ultrasound (CEUS) effectively identified the cause of stroke as the rupture of a vulnerable carotid artery plaque, forming a floating thrombus.

Case Presentation: A patient presented with acute stroke symptoms. CEUS clearly visualized the ruptured carotid artery plaque and the resulting floating thrombus, providing immediate diagnostic information.

Discussion: This case underscores the practicality and effectiveness of CEUS in diagnosing carotid artery plaque rupture as a cause of stroke. CEUS offers several benefits over traditional imaging modalities:

• Convenience and Speed: CEUS is readily available and provides rapid results, facilitating timely treatment decisions. * Safety: As a non-invasive procedure, CEUS eliminates radiation exposure and the risk of nephrotoxicity associated with contrast agents used in CTA and DSA.* Real-Time Imaging: CEUS allows for real-time visualization of blood flow and plaque morphology, aiding in accurate diagnosis.* Bedside Examination: CEUS can be performed at the bedside, minimizing patient discomfort and transport risks.

Conclusion: This case highlights the potential of contrast-enhanced ultrasound as a valuable tool in diagnosing carotid artery plaque rupture leading to stroke. Its advantages in safety, speed, and real-time imaging capabilities make it a practical and efficient diagnostic option.
