Pushing the limits forward: transradial superficial femoral artery stenting.

Percutaneous revascularization of superficial femoral artery (SFA) is increasingly carried out to treat patients with peripheral vascular disease and either intermittent claudication or critical limb ischemia. Transradial vascular access is increasingly adopted for invasive procedures due to reduced access-site complications and improved patient's comfort, compared with transfemoral. However, compared with coronary interventions, the adoption of transradial access in peripheral procedures is limited. Concerning SFA interventions, transradial access is usually prevented by the distance between the vascular access and the target lesion, which extends over the length of the currently available devices. Thanks to technical improvements, resulting in specifically dedicated low-profile equipment with adequate shaft length availability, transradial access is now feasible for the treatment of selected SFA lesions. We report the first two cases of SFA stenting performed by transradial access with a new specifically developed self-expanding nitinol stent with extended delivery system length. This report suggests that, with proper technique and specifically dedicated equipment, transradial SFA stenting is feasible. Treatment of SFA disease by transradial route, allowing for immediate post-procedure walking and simultaneous bilateral interventions, may represent an alternative for effective treatment of selected patients with SFA lesions.
