[A case report of disappearance of free internal thoracic artery graft stenosis].
We have experienced an interesting case of spontaneous disappearance of stenosis of the injured free internal thoracic artery graft six months after coronary artery bypass grafting. A 61-year-old male underwent coronary bypass surgery with in situ left internal thoracic artery (LITA)-left anterior descending (LAD) and free right internal thoracic artery (RITA)-first diagonal branch (D1) bypass at our hospital. Postoperative angiogram showed the stenosis of the distal portion of the free RITA. We judged it was the injury by the electrocautery when dissecting the RITA. He was admitted to our hospital and received repeat angiography because of recurrence of angina six months after surgery. Repeat angiogram showed the good patency of LITA and complete disappearance of the stenosis of the free RITA. We consider that this case proved the free ITA can be a living graft.
