冠状动脉造影正常患者64排CT冠状动脉成像结果分析

摘要

Objective To study the 64-detcctor computed tomography angiography( CTA) findings in patients with normal conventional coronary angiography results. Methods 52 cases with normal coronary angiography results underwent 64-detector CT angiography. CTA results were analyzed retrospectively. Results CT angiography showed 29 cases (n=29, 55. 77％ ) with vessel wall local thickening,23 cases without lumen stenosis, 6 cases with mild stenosis( mean 8％) ,8 cases(n=8,15. 38％ ) with diffuse vessel wall thickening,1 case without lumen stenosis,7 cases with mild stenosis(mean 11 ％ ) , 3 cases(n=3, 5. 77％) with pure vessel wall calcification, without vessel stenosis obviously. Conclusion 64-detector CT angiography is suitable in diagnosing coronarv heart discase as first choice.%目的 分析介入性冠状动脉造影正常患者64排CT冠状动脉成像的检查结果和影像特点.方法 对介入性冠状动脉造影结果为阴性的52例患者在1月内行64排CT冠状动脉成像检查,对阳性病例进行回顾性分析.结果 64排CT冠脉成像显示52例中,冠状动脉局限性管壁增厚29例(55.77%),管腔无狭窄23处,轻度狭窄6处,平均狭窄程度8%;弥漫性管壁增厚8例(15.38%),管腔无狭窄1例,轻度狭窄7例,平均狭窄程度为11%;单纯内膜钙化或管壁内钙化3例(5.77%),管腔未见明显狭窄.结论 64排CT冠状动脉成像更适宜作为冠心病诊断的首选影像检查方法.
