Long-term Patency and Clinical Outcome of the Viabahn Stent-Graft for Femoropopliteal Artery Obstructions

Outcomes following treatment of femoropopliteal in‐stent restenosis: A single center experience

“…This pattern of restenosis, in which the main body of the graft is free of restenosis and the edges restenose, appears to be characteristic of stent grafts [14][15][16]. Saxon et al [15], over a 4-year period of follow-up, reported that edge restenosis was present in up to 13.6% of 87 limbs treated with the Viabahn (W.L. Gore, Flagstaff, AZ).…”

“…Gore, Flagstaff, AZ). Edge restenosis may predispose stent grafts to stent thrombosis and stent-graft failure [15,17,18].…”

Primary Stenting in Femoropopliteal Occlusive Disease – What Is the Appropriate Role? –

“…The authors therefore suggested that the Viabahn was not suitable in situations where the landing zone was smaller than 4.5 mm in diameter. 24 Saxon et al later reported a multicenter randomized study comparing PTA with PTA followed by Viabahn placement. symptomatic femoral occlusive disease in 2005, several improvements in the stent design have been made.…”

Current treatment methods for long occlusions of the femoropopliteal segment in patients with intermittent claudication: Minireview

“…Advantages of a stentgraft include its ability to act against negative remodelation and minimize fractures and mechanical failure. A sufficient stentgraft diameter, the absence of massive calcifications in the artery, antiaggregation treatment and at least one patent lower leg artery are necessary to maintain patency 27,28 . Results of stentgraft implantation by Saxon after 4 years showed a 55% primary patency and 79% secondary patency; the results were not significantly affected by the length of the occlusion but by the diameter of the intervened artery 28 .…”

In cases of long occlusions longer than 15 cm where SIR was combined with stentgraft, primary patency was 75% after one year as compared to 28% in patients with SIR alone 29 .…”
