title: Three-dimensional computed tomography angiography for the preoperative evaluation of coronary artery disease in lung cancer patients.
abstract: BACKGROUND
  The number of elderly patients undergoing surgery for lung cancer is increasing. In this study, we assessed the usefulness of three-dimensional computed tomographicangiography (3D-CTA) for the detection of coronary disease in the elderly before surgical intervention for lung cancer.
  
  
  METHODS
  One hundred twenty patients admitted to our institution for lung cancer resection were enrolled in the study. 3D-CTA was performed in all 120 patients.
  
  
  RESULTS
  Seventy-one patients had normal findings, and forty-nine patients showed coronary stenosis on 3D-CTA examination. Among the latter 49 patients, 24 with slight stenosis underwent lung tumor resection, 23 had coronary angiography for severe stenosis before lung surgery and 2 were not eligible for lung resection because of very severe coronary stenosis. The diagnostic value of 3D-CTA was better than conventional CT.
  
  
  CONCLUSIONS
  This study suggests the usefulness of 3D-CTA for the preoperative diagnosis of coronary ischemic disease in elderly lung cancer patients.
