CT冠状动脉造影与单纯冠状血管造影术的回顾性研究

目的探讨CT冠状动脉造影替代单纯常规冠状血管造影术的可行性。方法选取2007年6月16日-2008年6月17日在我院心内科行单纯CCA并最大狭窄处≤50%的患者共568例,其中1个月内曾在我院行CTCA检查的患者102人,对比CTCA与CCA的结果。结果80例为单纯CCA检查,19例为支架植入术后复查,3例为冠脉旁路移植术后复查;CTCA诊断8例偏差,诊断符合率为92.2%;其中19例支架植入术后复查患者,CTCA诊断3例偏差,诊断符合率为84.2%。结论CTCA可较准确的鉴别无需再血管化治疗的患者,包括支架植入术后复查的患者。

Replacement of simple common coronary angiography with CT coronary angiography: A retrospective study

Objective To study the feasibility to replace simple common coronary angiography（CCA）with computed tomography coronary angiography（CTCA）.Methods A total of 568 patients with their greatest coronary artery stricture≤50%,as shown at simple CCA in our department from June 16,2007 to June 17,2008,were enrolled in this study.Of the 568 patients,102 underwent CTCA within 1 month after admission.The findings at CTCA and CCA were compared.Results Eighty patients underwent simple CCA,19 patients were checked after stenting,and 3 patients were reexamined after coronary artery bypass grafting（CABG）.Diagnostic errors of CCA and CTCA were found in 8 and 19 patients with a diagnostic rate of 92.2%and 84.2%,respectively.Conclusion CTCA can accurately determine patients who do not need revascularization including those after stenting and is,therefore,of an important value in clinical practice.
