Endoluminal stents for iliac and infrainguinal arterial disease

The primary objective is to assess the effects of different types of endoluminal stents (for example, bare metal, covered, drug-eluting) against each other for restoration of patency in iliac, SFA, popliteal and infrapopliteal artery occlusions or stenoses.

The secondary objectives are to assess the effectiveness of different types of stents in a) different participants (that is participants with claudication compared with participants with critical limb ischaemia) and b) different types of lesions based on the Trans-Atlantic Inter-Society Consensus II for each anatomical region (iliac, SFA, popliteal and infrapopliteal) (Dormandy 2000; Jaff 2015). In the absence of TASC II classifications, we will perform subgroup analyses with the lesions stratified into short (≤ 10 cm) or long (> 10 cm) stenosis or occlusion.

This is a protocol.
