Overlapping hybrid stenting with a sirolimus-eluting stent and a bare metal stent

Randomized follow-up studies revealed that sirolimus-eluting stent (SES) has an effect on reducing in-stent restenosis resulting from inhibition of neointimal proliferation comparing with bare metal stent (BMS). These data were obtained from separate patients. However, the response against different kinds of these two stents in the same patient had not yet been described. The present case was planned overlapping hybrid stenting with a SES and a BMS in tandem lesions. Not only intravascular ultrasound but also coronary angioscopy at three months follow-up studies showed that neointimal proliferation had been inhibited both in the SES alone segment and in the overlapping segment comparing with BMS alone segment. Our images clearly demonstrated the different degree of neointimal proliferation between the SES and the BMS in the same patient.
