Study Description

Brief Summary:

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 or disease	Intervention/treatment	Phase
Critical Limb Ischemia	Procedure: Vein collar at the distal anastomosis	Not Applicable

Study Design


Study Type :	Interventional (Clinical Trial)
Actual Enrollment :	352 participants
Allocation:	Randomized
Intervention Model:	Parallel Assignment
Masking:	None (Open Label)
Primary Purpose:	Treatment
Official Title:	Scandinavian Miller Collar Study
Study Start Date :	January 1995
Actual Primary Completion Date :	June 1998
Actual Study Completion Date :	June 1998

Arms and Interventions

Arm	Intervention/treatment
Experimental: Vein collar at distal anastomosis Vein collar at the distal anastomosis	Procedure: Vein collar at the distal anastomosis Vein collar interposed at the distal anastomosis or No vein collar interposed at the distal anastomosis
Experimental: No vein collar at the distal anastomosis No vein collar at the distal anastomosis	Procedure: Vein collar at the distal anastomosis Vein collar interposed at the distal anastomosis or No vein collar interposed at the distal anastomosis

Outcome Measures

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.
