RESUMEN
Objective To observe the primary clinical results of Gore （R） Viabahn endoprosthesis for atherosclerotic stenosis or occlusion in superficial femoral artery (SFA).Methods From March 2013 to November 2013,45 consecutive patients (54 limbs) who had ischemic symptom due to stenosis or occlusion of superficial femoral artery were treated by endovascular deployment of Gore （R） Viabahn endoprosthesis.We observed patency rate,improvement of Rutherford classification and ankle-brachial index,limb salvage rate and survival rate after 1,3 and 6 months.Results 43 patients (52 limbs)were followed-up,among which 32 patients(38 limbs)belonged to TASC Ⅱ type C or type D lesion.The mean (± SD) length of treated segment in 52 limbs was(19 ±4)cm.The rate of postoperative patency on duplex ultrasonography:one month,3 months and 6 months were 96.15％ (50 limbs),92.31％ (48 limbs)and 90.38％ (47 limbs) ; Ankle-brachial index increased from(0.32 ±0.20)to(0.68 ±0.18) (t =3.180,P ＜ 0.005) after 6 months ; at 6 months limb salvage rate was 96.08 percent (49 limbs),and survival rate was 97.67％ (42 patients).Conclusions Implantation of Gore （R） Viabahn endoprosthesis in atherosclerotic stenotic or occluded superficial femoral artery safely achieves a definite primary clinical effectiveness.
