摘要:
目的探讨机械式旋转血栓系统Rotarex治疗髂动脉和股腘动脉处支架内再狭窄的疗效。方法2018年6月~2019年6月我们对20例下肢动脉支架内再狭窄进行机械旋切处理，经造影明确髂动脉或股腘动脉支架内血栓形成，选择Rotarex机械血栓切除系统抽吸血栓。结果介入操作技术成功率为100%，4例存在残余狭窄病变，均行球囊扩张成形，其中2例植入覆膜支架。术前和术后踝肱指数(anklebrachial index，ABI)分别为0.38±0.24、0.91±0.31，差异有显著性(t=6.297，P=0.000)。并发症包括远端栓塞2例，穿刺点血肿2例，无肾功能不全、支架移位及断裂等并发症。20例平均随访13.1月(6~18个月)，1例因足趾坏疽合并感染行截趾术。术后6个月一期通畅率为80%(16/20)，免于靶血管血运重建率为85%(17/20)；术后12个月一期通畅率为75%(15/20)，免于靶血管血运重建率为85%(17/20)。结论Rotarex系统治疗下肢动脉支架内再狭窄的短期通畅率令人满意。
Abstract:
ObjectiveTo evaluate the therapeutic effect of Rotarex, a mechanical rotary thrombus system, on instent restenosis in iliac artery and femoral popliteal artery.MethodsA total of 20 patients with instent restenosis in lower extremity artery were treated by mechanical atherectomy from June 2018 to June 2019. The stent thrombosis in iliac artery or femoral popliteal artery was determined by angiography, and the Rotarex mechanical thrombectomy system was utilized for thrombus aspiration.ResultsThe success rate of the interventional procedure was 100%. Four patients had residual stenosis, and all of them underwent balloon dilatation, including 2 cases of coveredstent placement. The anklebrachial index of the 20 patients before and after operation was 0.38±0.24 and 0.91±0.31 (t=6.297, P=0.000), respectively. The complications included distal embolization in 2 cases and puncture site hematoma in 2 cases, respectively. There were no complications such as renal insufficiency, stent displacement or breakage. The 20 patients were followed up for an average of 13.1 months (range, 6-23 months). One patient underwent toe amputation due to gangrene complicated with infection. The primary patency rate at 6 months after surgery was 80% (16/20), and the nontarget vessel revascularization rate was 85% (17/20). The primary patency rate at 12 months after surgery was 75% (15/20), and the nontarget vessel revascularization rate was 85% (17/20).ConclusionThe Rotarex system can be used to treat instent restenosis in lower extremity artery, which gives a satisfactory shortterm patency rate.
