[A surgically treated case of coronary rupture by Palmaz-Schatz stenting].

We report a very rare case of coronary rupture by Palmatz-Schatz stenting. The reported patient, 74-year-old woman, had the stenosis of the left coronary artery. When she received PTCA, and directional coronary atherectomy for the left coronary artery, coronary dissection was developed. Though the coronary stenting using two Palmza-Schatz stents for the dissection was attempted, extravasation of a contrast medium after post dilatation by a balloon was found. Since reupture of the left coronary artery was strongly suspected, the emergency operation was required. Hemostasis and the coronary artery bypass grafting using two saphenous veins were performed successfully. We thought that post dilatation by balloon caused the coronary rupture.
