[Coronary artery bypass grafting to left anterior descending coronary artery diagnosed by multidetector-row computed tomography].

: A 64-year-old male received coronary angiography because of chest pain. Although coronary angiography showed total occlusion of right coronary artery (RCA) # 2 and left anterior descending branch (LAD) #6, and a significant stenosis of left circumflex (LCx) #11, it could not visualize LAD distal to LAD # 6. Since coronary multidetector-row computed tomography (MD CT) could visualize the distal LAD, coronary artery bypass grafting (CABG) was indicated for this patient. Left internal thoracic artery (LITA) was anastomosed to LAD and saphenous vein graft (SVG) was used for distal anastomoses to obtuse marginal branch (OM) and 4-posterior descending branch (# 4 PD). Postoperative course was uneventful. LITA anastomosed to LAD and SVG to OM and # 4 PD were visualized by postoperative coronary angiography. MD CT in addition to coronary angiography was demonstrated useful to assess precise lesions of the coronary artery disease in this case.
