In 100 consecutively operated patients with 167 aortocoronary bypass grafts (ACVB) routine catheterisation was performed three month postoperatively, as well as sequential, ECG-gated and dynamic computed tomography (CT) the day before angiography. The results showed a sensitivity of 92%, a specificity of 67% and an overall accuracy in 81% for CT. Serial (dynamic) CT provides for quantitative assessment of attenuation values of contrast medium enhancement in ACVB and aorta, which improves security of the CT-test in most patients with patent grafts. Therefore clinical contribution of CT will be greatest for routine screening post-operatively and for assessment of ACVB--patency in asymptomatic patients.
对100例连续接受手术且有167条主动脉冠状动脉搭桥术(ACVB)的患者,术后3个月进行了常规导管插入术,并在血管造影前一天进行了连续的、心电图门控的动态计算机断层扫描(CT)。结果显示,CT的敏感性为92%,特异性为67%,总体准确率为81%。连续(动态)CT可对ACVB和主动脉中造影剂增强的衰减值进行定量评估,这提高了大多数移植血管通畅患者CT检查的安全性。因此,CT对术后常规筛查以及无症状患者ACVB通畅性的评估具有最大的临床价值。
