Abstract:
Objective To analyze the clinical features of Takayasu′s arteritis (TA) and to evaluate the usefulness of 2D color Doppler flow imaging (2D CDFI) and digital subtraction angiography (DSA) in diagnosing TA.Methods Fifty eight patients with TA were analyzed.In 26 cases,the 2D CDFI findings were compared with that of DSA.Results ① One hundred and eighty two peripheral arteries were involved in 58 patients including 176 arteries with stenosis or occlusion,mainly with aortic arch syndrome and left side involved.② Compared with DSA,2D CDFI had a higher sensitivity (88%) in diagnosing stenosis and occlusion of vessel cavity in aorta and its main branches,and had a positive predictive value of 100% and anegative predictive value of 0% respectively.Conclusion 2D CDFI has some outstaning features as non invading,safety,cheapness and so on in diagnosing TA,compared with DSA that is usually used as "the gold standard" for the definitive diagnosis of this disease.2D CDFI is able to depict vessel wall thickening,which is a major pathologic feature of the disease and it is suitable for long term repeated follow up.
