[Kinking of skeletonized internal thoracic artery graft].
A 66-year-old woman underwent coronary artery bypass grafting (CABG). Postoperative angiography on postoperative day (POD) 11 revealed that right internal thoracic artery (RITA) anastomosed to left anterior descending artery (LAD) had a kinking. The angiography performed 30 months after operation revealed no specific changes in the kinking of RITA and in the left ventricular function. Another case was a 74-year-old man with chronic renal failure under hemodialysis. He underwent CABG with left internal thoracic artery (LITA) to LAD. Post-operatively he had chest pain during hemodialysis. On POD 10, angiography revealed that LITA had a kinking with moderate stenosis and normal left ventricular function. The angiography performed 10 months after operation revealed no specific changes in the kinking of LITA. However, left ventriculography revealed akinesis in the antero-apical region. It suggested that the viability was lost due to the graft kinking of LITA and steal phenomenon on hemodialysis.
