RESUMO
Objective:To investigate the clinical application value of ultrasound in the diagnosis and differential diagnosis of Takayasu arteritis (TA ). Methods: A total of 39 suspected TA patients were examined by ultrasonography,erythrocyte sedimentation rate (ESR),C reactive protein (CRP)and CT angiography (CTA), and the ultrasound examination results were compared and analyzed with the final chinical diagnosis results. Results:Of the 39 cases of suspected TA patients which had been examined by ultrasound,33 cases were diagnosed as TA,2 cases were diagnosed as atherosclerosis (AS),2 cases were diagnosed as fibromuscular dysplasia (FMD) and 2 cases were diagnosed as thromboangiitis obliterans (TAO).Compared with final chinical diagnosis results, 1 FMD patient was misdiagnosed as TA,and the rest of the diagnostic results were consistent with the final chinical diagnosis results.Conclusion:Ultrasound examination can provide objective and accurate basis for the diagnosis and differential diagnosis of TA,and it is an effective method of imaging examination.
