[A case report of bilateral free internal mammary artery bypass grafting reoperation--spontaneous resolution of stenotic LAD graft one year after revascularization].
We experienced a coronary artery bypass reoperation utilizing bilateral free internal mammary artery (IMA) grafts for a 68 year old male with unstable angina due to graft occlusion. Although post-operative early graftgraphy showed LAD graft stenosis, it resolved completely at the second graftgraphy one year after the operation. Recently in situ IMA grafting has become a standard method for coronary artery revascularization because of its long term high patency rate. On the other hand, free IMA grafting has been rarely tried in our country. Though there has been a few reports of the growth and enlargement of in situ IMA graft, similar events in free IMA graft are rare and not found in the literature. We feel our case of spontaneous resolution of free IMA graft stenosis is unique and worth reporting.
