Clinical value of contrast-enhanced ultrasound and conventional ultrasound in the diagnosis of carotid artery stenosis

Objective To investigate the value of ultrasonography and conventional ultrasound in the diagnosis and treatment of carotid stenosis. Methods A total of 50 patients with carotid artery stenosis confirmed by digital subtraction angiography (DSA) in hospital from October 2015 to October 2017 were selected. All the patients were examined by CEUS and conventional ultrasound, and these two diagnostic methods were evaluated. The DSA examination was taken as the gold standard, the diagnostic accuracy, sensitivity, specificity of two methods were assessed. Results Compared with conventional ultrasound, the diagnostic results of CEUS and DSA were more similar; The DSA diagnosis was taken as the gold standard, the accuracy of CEUS in the diagnosis of carotid artery stenosis was higher than that of conventional ultrasound (P<0.05). Conclusions Ultrasonography has high accuracy in carotid stenosis and can effectively evaluate the degree of stenosis, and provid an important basis for clinical treatment.
