| Popis: | A 69-year-old man was admitted to our hospital complaining exertional chest pain for 1 month. He had undergone coronary bypass surgery 8 years ago. Two SVGs were implanted for left anterior descending coronary artery and left circumflex coronary artery (LCx). He has a history of percutaneous coronary intervention and stent implantation for the connection of the graft to LCx 1 year ago. Coronary multidetector computed tomography (MDCT) was performed using a 16-slice scanner (LightSpeed 16, GE Systems, USA). The 80 ml of contrast medium (Optiray 320; Tyco Healthcare Co., Ltd., Japan) was used for MDCT at 3.5 ml/s after test injection (15 ml). The slice thickness was 0.625 mm, pitch was 0.3:1, rotation time was 0.5 s, temporal resolution was 125 ms and the trigger point was 70–80% (R–R). Cross-sectional images of the coronary arteries were obtained by applying the curved multiplanar reformation technique and were analyzed with a plaque detecting system, Plaque Map [1]. MDCT demonstrated the severe stenosis in the middle portion of SVG for LCx (Fig. |
