title: Late-term regression of stenosis at the kink site in the internal thoracic artery in two cases.
abstract: A kink in the internal thoracic artery (ITA) is a rare postoperative complication after coronary artery bypass surgery. The kink can be accompanied by significant stenosis and has been observed after the ITAs are harvested by the skeletonization method. In this report, we present two cases in which early postoperative angiography showed the kink accompanied by significant stenosis, and late angiography revealed regression of stenosis at the kink site. Immediate intervention is not always necessary even when the kink, accompanied by significant stenosis was observed on early postoperative angiography.
