 The patient was a 62-year-old female in whom angina pectoris was suspected in March, 2005, during hospitalization in the orthopedic department for diabetic gangrene of the patient's leg, and she was referred to our department. Coronary angiography detected 90% stenosis of #1, and TUNAMITM(2.5×15mm) and CypherTM(2.5×18mm) were implanted in distal and proximal regions of #1, respectively. On follow-up after 4 months, the CypherTM and TUNAMITM stents were 90% and 99% occluded. Intravascular ultrasonography detected that the CypherTM stent had migrated for 3mm toward the distal side from the ostium, which had caused severe proliferation of the intima in the uncovered ostial region. CypherTM(3.0×28mm) was implanted at a site 1-strut out of the ostium of the right coronary artery. Anginal attack occurred in January, 2006, and the patient visited our hospital. The #1 ostium was 99% occluded, and the CypherTM stent was fractured and dislocated into the aorta for 3-struts. The occlusion was reduced to 50% by balloon dilatation, but chest pain and severe atrioventricular block occurred on the same day. The patient transferred to another hospital for bypass surgery. The migration and fracture may have been closely associated with the first and second restenosis, respectively.
