title: Systolic segmental disappearance of internal mammary artery graft. Correlation with prolonged spasm of the graft.
abstract: Vasospasm of the saphenous vein and internal mammary grafts may develop spontaneously under several conditions. We present for the first time spasm of a left internal mammary artery bypass graft during coronary arteriography. A patient who underwent coronary artery bypass operation 4 years ago was recatheterized because he developed chest pain. Selective catheterization of the left internal mammary artery graft showed disappearance of its lumen at its distal part during systole, whereas the patient developed angina. These phenomena disappeared after intravenous nitroglycerin administration.
