PTA versus Palmaz Stent Placement in Femoropopliteal Artery Obstructions: A Multicenter Prospective Randomized Study

The influence of composition and location on the toughness of human atherosclerotic femoral plaque tissue

“…This is achieved by the stent acting as a permanent implant therefore supporting the tissue. However, it does not substantially improve primary patency [15][16][17] due to exaggerated neointimal hyperplasia that leads to instent restenosis in 20-40% of patients at 2 years [18,19]. Drug eluting stents have been employed in the femoral arteries to address the issue of in-stent restenosis by delivering an anti-restenotic drug to the treated area.…”

Endovascular Techniques in Limb Salvage: Stents

“…10 The initial reports evaluated the use of balloon-expandable stents compared with angioplasty alone. 11 Those reports found that there is no difference in 1-and 2-year angiographically determined patency rates between these groups. Since then, use of nitinol stents has expanded with somewhat conflicting results, although there is evidence of the beneficial effect of these stents, especially in long lesions.…”

Current Trends and outcomes: Endovascular Management in Arteriosclerosis Obliterans (ASO) of Lower Limb Vessels

“…In general, we can say that short lesions, less than 10 cm, preferably with stenosis, are the most suitable for endovascular treatment. [40,41,42,43] In longer lesions, the use of expanded polytetrafluoroethylene coated stents seems to provide advantages over the other methods, though randomized studies with a greater follow-up are required. [44] In surgery plus combined with adjuvant medical treatment, prior to open or endovascular surgery an indefinite program of anti-aggregation is necessary.…”
