摘　　要：目的探讨Rotarex机械血栓切除联合药物涂层球囊(drug-coated balloon,DCB)扩张治疗股腘动脉硬化闭塞症支架内再狭窄(in-stent restenosis,ISR)的有效性和安全性。方法回顾性分析2020年3月~2022年3月53例下肢动脉硬化闭塞支架植入后再狭窄资料。覆膜支架9例,裸支架44例。均行Rotarex机械血栓切除联合DCB扩张治疗。术后予抗血小板及抗凝治疗。结果53例均下肢动脉再通成功。Rotarex机械血栓切除联合DCB扩张治疗后造影,3例支架内残余血栓,留置溶栓导管溶栓,复查造影显示血流恢复;5例膝下动脉栓塞,其中胫腓干动脉开口处3例,经6F外周血栓抽吸导管吸栓后血流通畅,胫后动脉近段闭塞2例,经球囊扩张后血流通畅。3例残余狭窄>30%,置入补救性支架。术后未出现穿刺点相关并发症,无心脑血管意外或死亡。术前踝肱指数(ankle brachial index,ABI)0.33±0.06,术后出院时0.84±0.07(t=-39.443,P<0.001)。53例均完成3个月随访,52例完成6个月随访,49例完成12个月随访。一期通畅率术后3个月100%(53/53),6个月92%(48/52),12个月84%(41/49)。2例再次出现下肢缺血症状,分别于术后9、10个月行DCB扩张。12个月免于临床驱动的靶血管再干预率为95.9%(47/49)。死亡4例(1例消化道出血,2例新冠肺炎,1例不详),踝关节以远截肢3例。结论Rotarex机械血栓切除系统联合DCB治疗股腘动脉ISR安全有效,通畅率和再干预率满意。Objective To investigate the efficacy and safety of Rotarex mechanical thrombectomy combined with drug-coated balloon(DCB)dilatation for the treatment of in-stent restenosis(ISR)in femoropopliteal atherosclerotic occlusive disease.MethodsA total of 53 patients with in-stent restenosis after stent implantation(9 covered stents and 44 bare stents)from March 2020 to March 2022 were retrospectively analyzed.All the cases were treated with Rotarex mechanical thrombectomy combined with DCB dilatation.Antiplatelet and anticoagulant therapy were used after operation.Results All the 53 patients had successful recanalization of the lower limb arteries.Imaging after Rotarex mechanical thrombectomy combined with DCB dilatation showed 3 cases of residual thrombus in the stent treated with indwelling thrombolytic catheters for thrombolysis,with follow-up angiography showing blood flow recovery,and 5 cases of embolism of the below-knee arteries intraoperatively,including 3 cases at the opening of the tibiofibular trunk artery,which were opened with 6F peripheral thrombus aspiration catheter until unobstructed blood flow,and 2 cases of proximal occlusion of the posterior tibial artery,which were opened with balloon dilatation.Three cases of residual stenosis>30%were treated with remedial stents placement.There were no postoperative complications related to the puncture point,cardiovascular or cerebrovascular accidents,or deaths.The ankle brachial index(ABI)was 0.33±0.06 preoperatively and 0.84±0.07 postoperatively at the time of discharge(t=-39.443,P<0.001).All the 53 cases completed 3-month follow-ups,52 cases completed 6-month follow-ups,and 49 cases completed 12-month follow-ups.The phaseⅠpatency rates were 100%(53/53)at 3 months,92%(48/52)at 6 months,and 84%(41/49)at 12 months,postoperatively.Recurrence of lower limb ischemic symptoms happened in 2 cases,which were given DCB dilatation at 9 and 10 months postoperatively,respectively.The 12-month freedom from clinically-driven target vessel reintervention was 95.9%(47/49)
