Abstract:
Objective To evaluate the safety and efficacy of SilverHawk directional atherectomy device in the treatment of arterial stenoses/occlusions of the femoropopliteal regions.Methods From April 2011 to May 2012,36 patients (28 men,8 women,age range 60 - 84y) with 40 arteriosclerotic lesions of femoro-popliteal arteries (de novo lesions in 25 arteries,in-stent restenosis in 15 arteries; Rutherford score of 3 - 5 ) were included in the treatment by SilverHawk directional atherectomy device.All the patients were diagnosed via low-extremity artery CTA and arteriography.The mean ankle brachial index (ABI) of treated limbs was 0.53 ±0.12.Results The overall technical success rate was 100％ (40/40).The procedural success rate was 87.5％ (35/40).There was no perioperative mortality with three cases developing complications,vascular injury occurred in two cases.One was treated by stent-graft while the other was managed conservatively; Procedure-related arterial embolization occurred in one case and was treated by suction through catheter.Symptoms were relieved in all patients,ABI increased to 0.72 ± 0.18.All the patients were followed up for an average of (6.4 ± 1.2) months.Postoperative restenosis developed in one case and treated with balloon angioplasty and stent placement after six month.Conclusions SilverHawk directional atherectomy device is effective and safe in treament of arterial stenoses/occlusions of the femoropopliteal lesions,with satisfactory early results.
