Prospective assessment of nitinol self-expanding stent expansion in the superficial femoral artery with debulking and post-dilation strategies




Background


Maximal expansion of nitinol self-expanding stents (n-SES) implanted in the superficial femoral artery (SFA) could be influenced by pre-implant debulking or post-dilation strategies which may affect clinical outcomes.




Methods


We prospectively evaluated 32 n-SES, implanted in 16 limbs of 14 patients with symptoms classified as Rutherford category ≥2 and mean baseline ankle-brachial index (ABI) of 0.61±0.10 enrolled in the ongoing COBRA (PolarCath cryoplasty vs. conventional balloon post-dilation of nitinol stents for peripheral vascular interventions) trial with duplex ultrasound (US) immediately post-procedure.
