About this trial
This is an interventional treatment trial for Critical Limb Ischemia focused on measuring Graft patency, Limb salvage

Outcomes
Primary Outcome Measures
Primary graft patency
Follow-up at 1, 3, 6, and 12. Thereafter at most 5 years or until death of patient or amputation of limb. Primary graft patency = patent graft without any intervention to open up or prevent a graft ocklusion. Methods used for verification of patency: angiography, duplex, an improved ankle-brachial index was mantained, palpable pulse, or bi- or triphasic Doppler signal over the graft.
Secondary Outcome Measures
Secondary Patency
Secondary patency = patent graft after one or several interventions to open up or prevent a graft occlusion. Methods used for verification of secondary patency: angiography, duplex, an improved ankle-brachial index was mantained, palpable pulse, or bi- or triphasic Doppler signal over the graft.
