Purpose

Randomized study to evaluate the effect of adding a vein collar at the distal anastomosis to PTFE-grafts used for bypass to below knee arteries in patients with critical limb ischemia with respect to primary patency, secondary patency, and limb salvage

Condition	Intervention
Critical Limb Ischemia	Procedure: Vein collar at the distal anastomosis


Study Type:	Interventional
Study Design:	Allocation: Randomized Intervention Model: Parallel Assignment Masking: None (Open Label) Primary Purpose: Treatment
Official Title:	Scandinavian Miller Collar Study

Primary Outcome Measures:

Primary graft patency [ Time Frame: Up to five years ]
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 [ Time Frame: Up to five years ]
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.
