Abstract:

BACKGROUND: Stent implantation has become the main treatment method of Trans-Atlantic Inter-Society Consensus II (TASCII) C and D’s femoropopliteal lesions, but the lesions are always too long that we have to implant mixed stents to overlap the arteries.
OBJECTIVE: To evaluate the up to mid term safety and efficacy of different self-expending metal stents for treatment of femoropopliteal arteriosclerosis obliterans.
METHODS: Thirty patients with long-segmental femoropopliteal arteriosclerosis obliterans (40 affected limbs) were enrolled, including 34 males and 5 females, aged 44-87 years old. Each affected limb was implanted with one LifeStent with another one or two different kinds of stents. After 39 months of follow-up, the successful stenting rate, post-implantation biocompatibility, limb salvage rate, primary and secondary patency rate were evaluated.
RESULTS AND CONCLUSION: Totally 93 stents were implanted in the 40 affected limbs, including 27 affected limbs with 2 stents and 13 affected limbs with 3 stents. There were 40 LifeStent stents, 45 Luminexx stents, 1 Smart stent, 2 Aurora stents, 2 Pulsar18 stents, and 3 Invatec stents, with a successful stenting rate of 92%. The limb salvage rate at 12 months was 95%. A 24 months after surgery, the primary and secondary patency rates were (42.0±0.1)% and (59.0±3.7)%, respectively. There was no severe complication and inhospital mortality. These findings suggest that the mixed implantation of self-expending stent implantation (LifeStent mixed with other kinds of stents) for femoropopliteal arteriosclerosis obliterans appears to be safe and efficient during the up to mid term.
