To retrospectively examine the technical feasibility and safety of directional atherectomy for treatment of subacute infrainguinal arterial vessel occlusions.
Five patients (one woman, four men, age range 51-81 years) with peripheral arterial disease who experienced sudden worsening of their peripheral arterial disease-related symptoms during the last 2-6 weeks underwent digital subtraction angiography, which revealed vessel occlusion in native popliteal artery (n = 4) and in-stent occlusion of the superficial femoral artery (n = 1). Subsequently, all patients were treated by atherectomy with the SilverHawk (ev3 Endovascular, USA) device.
The mean diameter of treated vessels was 5.1 ± 1.0 mm. The length of the occlusion ranged 2-14 cm. The primary technical success rate was 100%. One patient experienced a reocclusion during hospitalization due to heparin-induced thrombocytopenia. There were no further periprocedural complications, in particular no peripheral embolizations, until hospital discharge or during the follow-up period of 1 year.
The recanalization of infrainguinal arterial vessel occlusions by atherectomy with the SilverHawk device is technically feasible and safe. In our limited retrospective study, it was associated with a high technical success rate and a low procedure-related complication rate.
回顾性研究定向动脉切除术治疗亚急性下肢动脉血管闭塞的技术可行性和安全性。
5 名（1 女，4 男，年龄 51-81 岁）患有外周动脉疾病的患者，在过去 2-6 周内经历了外周动脉疾病相关症状的突然恶化，进行了数字减影血管造影，结果显示在原生腘动脉（n=4）和股浅动脉支架内闭塞（n=1）处存在血管闭塞。随后，所有患者均采用 SilverHawk（ev3 血管内，美国）装置进行动脉旋切术治疗。
治疗血管的平均直径为 5.1±1.0mm。闭塞长度为 2-14cm。主要技术成功率为 100%。1 名患者因肝素诱导的血小板减少症而在住院期间再次发生闭塞。在住院期间或 1 年的随访期间，没有发生进一步的围手术期并发症，特别是没有发生外周栓塞。
采用 SilverHawk 装置的动脉旋切术对下肢动脉血管闭塞进行再通是可行且安全的。在我们有限的回顾性研究中，它与高的技术成功率和低的手术相关并发症发生率相关。
