[Comparison between angiographic and computed tomographic imaging of aortocoronary bypasses in 100 patients].
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.
