Evaluating carotid atherosclerotic plaques stability with contrast-enhanced ultrasonography
2008
Objective To evaluate the relationship between carotid atherosclerotic plaques stability and the clinical symptoms of carotid atherosclerosis by contrast-enhanced ultrasonography. Methods Fifty patients with carotid atherosclerotic plaques were examed with contrast-enhanced ultrasonography,the contrast agent visualization of the carotid atherosclerotic plques were analyzed and compared with their clinical symptoms. Results Twenty-three patients who suffered from obvious clinical symptom were entirely visualized. Twenty-weven patients had not apparent clinical symptom,of these patients,15 were sparse visualized,there was no visualization in other 12 patients. Conclusions Conlrast enhanced ultrasonography can real-time observe microcirculation in carotid atherosclerotic piques,and assess the stability of carotid atherosclerotic plaques.
