[A case of new stenosis in the distal portion following transaortic patch angioplasty for the left main coronary stenosis].
A 75-year-old man who had unstable angina underwent transaortic vein patch angioplasty for isolated 60% stenosis of the left main coronary artery. About four months after the operation, he developed effort angina and angiographycally new stenosis was detected in the distal portion of patch dilatation. So he underwent emergency aorto coronary bypass grafting. Transaortic patch angioplasty is attractive technique because of restoration of the original antegrade coronary flow, but this direct surgical approach may induce the stimulation of intima, and may injure the intima. It is important to bear this technique in the mind for selected patients with left main coronary lesions.
