【摘要】 目的探讨螺旋CT血管三维成像检查多发性大动脉炎的诊断价值。方法回顾性分析56例大动脉炎患者的螺旋CT三维血管成像特点。结果56例大动脉炎病变血管清晰显像,共发现受累血管175支,其中累及最多的为锁骨下动脉(36.00%,63/175),且左锁骨下动脉所占比率较高(24.00%,42/175),其次是颈总动脉(29.71%,52/175),肾动脉(10.86%,19/175);受累动脉管壁不同程度地向心性或偏心性增厚,管腔狭窄或闭塞。结论多层螺旋CT三维血管成像可明确多发性大动脉炎的诊断及病变范围、程度和性质,值得临床推广应用。更多还原

【Abstract】 Objective To assess the application of spiral CT angiography in the diagnosis of Takayasu arteritis.Methods Vascular imaging features of three-dimensional CT angiography of 56 patients with Takayasu arteritis were analyzed retrospectively.Results The vascular imaging of all the patients were qualified for diagnosis.A total of 175 arteries were involved,including subclavian arteries(36.00%,63/175) with a high percentage of the left subclavian arteries(24.00%,42/175),common carotid arteries(29.71%,52/175) and renal arteries(10.86%,19/175).The affected artery wall had varying degrees of concentric or eccentric thickening,and stenosis or occlusion of lumen was observed.Conclusion Three-dimensional spiral CT angiography can make clear diagnosis of Takayasu arteritis,including the scope,extent and nature,and thus is worthy of clinical application.更多还原
