The diagnostic value of 3D-DSA,TCD and carotid ultrasonography in transient ischemic attack in carotid artery system

Objective To evaluate the value of three dimensional digital subtraction angiography(3D-DSA),transcranial doppler sonography(TCD)and carotid ultrasonography in diagnosis of transient ischemic attack(TIA)in carotid artery system.Methods 3D-DSA,TCD and carotid ultrasonography examinations were performed in 63 patients with carotid disease,and then the abnormality of carotid artery system was analyzed.Results 3D-DSA abnormality of carotid artery was 18 cases(28.6%),cerebral artery abnormality was 48 cases(76.2%),and 12 cases were abnormal in both,while most of them showed mild-severe carotid artery stenosis;the abnormality of TCD was 45 cases(71.4%);and the abnormality of carotid ultrasonography was 24 cases(38.1%),in which 18 cases were carotid artery 3D-DSA abnormal.Conclusion United application of 3D-DSA,TCD and carotid ultrasonography can perform objective evaluation on the etiology and diagnosis of carotid disease.As the gold standard for the diagnosis and treatment of cerebral or carotid artery stenosis as well as selection of therapeutic regimen,DSA plays an impotant role in the further interventions of ischemic cerebrovascular disease.
