研究目的:

评估药物涂层球囊在下肢动脉硬化闭塞症支架植入术后支架内再狭窄的有效性和安全性。  

Objectives of Study:

The aim of this study was to estimate the efficacy and safety of drug-coated balloon in the treatment of in-stent restenosis of lower extremity arteriosclerosis obliterans.

药物成份或治疗方案详述:

手术前所有患者均口服“双抗”(阿司匹林+氯吡格雷)至少三天,并根据患者影像学检查以及体格检查选择穿刺方法,多数采用健侧穿刺翻山患侧的方法,穿刺成功后,置入6F血管鞘(Cook公司,美国),造影再次确认患者为ISR,静脉注射肝素0.6-0.8mg/kg,随后按照10mg/h追加肝素量。以椎动脉导管或支撑导管配合0.035超滑导丝(Terumo公司,日本)或V18导丝(Boston Scientific公司,美国)开通支架内闭塞病变直至膝下动脉,选择普通球囊从小到大递增性对支架内病变进行预扩张,再次患肢动脉DSA造影了解开通情况,满意后选择合适口径(小于支架直径0.5-1mm)DCB (先瑞达公司,中国,直径3-5.5mm,长度120-300mm,涂层药物为紫杉醇,药物浓度是3μg/mm2。)进行扩张,扩张时间为180s,压力为8~10个大气压。扩张完成后,再次造影观察狭窄处回缩情况,若再次造影显示病变段血流通畅,且残余狭窄<30%即视为手术成功。若回缩>30%,则补入支架。术后所有患者均皮下注射低分子肝素钙3-5天,静脉滴注罂粟碱30mg,2次/天,直至出院。术后继续口服抗血小板药物氯吡格雷及阿司匹林6个月。
