Capacities of multidetector spiral computed tomography in the planning and postoperative examination of patients undergoing coronary artery bypass surgery

Summary:Multiple investigations show that multidetector spiral computed tomography (MSCT) bypass grafting becomes an alternative to invasive coronary angiography in detecting coronary graft stenoses and occlusions. The investigation retrospectively estimated the patency of aortocoronary and mammary coronary artery anastomoses by MSCT bypass grafting. Examinations were made in 85 (326 anastomoses) patients who had undergone aortocoronary and mammary coronary artery bypass surgery and had MSCT bypass grafting within 3 years after the surgery. In the first year following the surgery, 18 patients with graft stenotic changes, as evidenced by MSCT, underwent intervention coronary angiography, the sensitivity and specificity of which was 100%. The results of clinical and instrumental examinations were also compared with graft incompetence, as shown on MSCT that revealed that MSCT bypass grafting was the only noninvasive technique to evaluate early coronary graft closure both in the absence of clear signs of myocardial ischemia according to the data of exercise tests and in the presence of recurrent angina pectoris.
