Superficial femoral artery recanalization with self-expanding nitinol stents: long-term follow-up results.

PURPOSE: Since long-term patency and device integrity of nitinol stents in SFA lesions are not well studied, we examined clinical outcome, patency and device integrity after stenting long lesions using a standardized implantation technique. METHODS: Between 2001 and 2006, 59 patients (74 lesions) were treated with the same nitinol self-expandable stent (Zilver, Cook, USA) and technique for SFA recanalization. Clinical charts and imaging were retrospectively reviewed for patency (primary and assisted-primary), and device integrity. RESULTS: Patients were 74.5 (10.9) years old (range 49 to 93), 64% male, 42% diabetic, 62% hypertensive and 67% current or former smokers. Lesions were 23% TASC B, 16% TASC C, or 61% TASC D. Mean recanalization length was 19 cm (range 3 to 53). Mean number of stents per patient was 2.8 (total 210). Mean follow-up time was 2.4 years (range 3 days to 4.8 years). Kaplan-Meier estimates for primary patency rates were 90%, 78%, 74%, 69%, and 69% at 1, 2, 3, 4 and 4.8 years, respectively. Ten restenoses at a mean of 500 (388) days (1-1251 days) were successfully recanalized. The assisted primary patency rates were 96%, 90%, 90%, 90% and 90% at 1, 2, 3, 4 and 5 years, respectively. Six complete occlusions could not be reverted by a second recanalization procedure, and were treated by surgical bypass (1 case), amputation (3 cases), or medical management (2 cases). One (1.04%) Class II stent fracture was noted. CONCLUSIONS: SFA recanalization with a standardized implantation technique and nitinol stents provides good long-term primary and assisted-primary patency.     

股浅动脉首期置入自膨式支架与球囊扩张成形的疗效比较

Objective To compare the mid-term clinical results of primary implantation of a selfexpanding nitinol stent and primary percutaneous transluminal angioplasty (PTA) for long range arteriosclerosis obliterans of the superficial femoral artery. Methods From December 2005 to February 2007,109 patients who had moderate-severe claudication or chronic limb ischemia (CLI)due to stenosis or occlusion of the superficial femoral artery were treated by endovascular technology. 53 patients (73 limbs) were treated by primary stenting and 56 patients (76 limbs)by PTA. We compared the clinical data of stenting group and PTA group at 6,12 and 24 months. Results The mean length of the treated segment was (16± 8)cm in the stenting group and(15±7)cm in the PTA group. At 6 months, the rate of restenosis on duplex ultrasonography was 13.7% in stenting group and 30.2% in PTA group (X2=4.09, P<0.05);at 12 months the restenosis rates were 25.5% in stenting group and 46.9% in PTA group(X2=4.75, P<0.05);at 24 months the restenosis rates on duplex ultrasonography were 38.1% in stenting group and 65.9% in PTA group(X2=6.66, P<0.01). Rutherford stages in stenting group were significantly better than those in PTA group. Conclusion In the mid-term, primary implantation of a self-expanding nitinol stent yielded results that were superior to those with PTA for arteriosclerosis obliterans or long range stenosis of the superficial femoral artery.
