摘要
目的 探讨大动脉炎 (TA)临床特点及二维彩色多普勒超声 (2D CDFI)和X线数字减影血管造影 (DSA)对TA的诊断价值。方法 分析 5 8例TA患者 ,对其中同时采用 2D CDFI和DSA的 2 6例患者进行了比较。结果 ① 5 8例TA患者总共有 182支血管受累 ,其中狭窄、闭塞性改变者 176支 ,以头臂动脉受累几率最高 ,左侧受累居多。②与DSA相比 ,2D CDFI在显示大动脉主干血管狭窄和闭塞方面的阳性预测值为 10 0 % ,阴性预测值为 0 ,灵敏度为 88%。结论 2D CDFI具有安全、无创、价廉、便捷等特点 ,目前虽不能替代DSA作为诊断TA的“金标准” ,但它可显示动脉管壁增厚这一TA主要病理特征 。
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.
