摘要
背景:再狭窄复发可发生于药物洗脱支架置入治疗裸金属支架(BMS)支架内再狭窄(ISR)后,尤其好发于药物洗脱支架间隙区域。方法:为研究ISR经西罗莫司洗脱支架(SES)置入治疗后新生内膜进展和管腔狭窄的详细信息,纳入65例发生ISR的患者。
Background: Recurrent restenosis may occur after drug-eluting stent implantation for in-stent restenosis(ISR) of bare metal stents(BMSs), especially in areas involving drug-eluting stent gaps. Methods: To investigate the details of neointimal progression and luminal narrowing after the treatment of ISR using sirolimus-eluting stents(SESs), serial intravascular ultrasound analysis was performed in 65 patients with ISR at postintervention and at 6-month follow-up. The total stented segment was categorized int...
