256层螺旋CT在主动脉缩窄诊断中的价值

Clinical Siagnostic Value of 256-Slice Spiral CT in Coarcation of Aorta

目的探讨256层螺旋CT(MSCT)在先天性主动脉缩窄(CoA)诊断中的应用价值。方法对19例经手术或DSA证实的CoA影像学表现进行回顾性分析,探讨256层螺旋CT血管成像对其病理分型与合并畸形的诊断价值。结果 19例CoA术前CT均诊断正确,诊断准确率100%。对合并的畸形,如动脉导管未闭(PDA)、主动脉骑跨、大动脉转位、肺动脉狭窄、体肺侧枝循环术前CT均正确诊断。结论 256层螺旋CT作为一种无创性血管造影技术,对于CoA及其合并的其他畸形,具有重要的诊断价值,可作为患者检查的首选。

Objective To evaluate the clinicaldiagnostic value of 256 -slice spiral CT （MSCT） in Conjenital coarcation of aorta （COA）. Methods Ninteen cases of COA confirmed by surgery or DSA were retrospectively analyzed Results Ninteen patients with COA were diagnosed correetly by MSCT and proved by surgery or DSA.For the combined malformations,such as single ventricle。 patent ductus arteriosus（PDA）。 overriding aorta,transposition of conducting arteries,and collateral circulation were all correctly diagnosed,while. Conclusion As an excellent non—invasive diagnosis modality in diagnosing COA and combined malformations 256-slice spiral CT provides an objective reference for clinical approach,and can be used as a method first choice in its diagnosis.
