Outcome Measures

Primary Outcomes (1)

  • Incidence of primary patency of the venous bypass

    The incidence of patency of the venous bypasses will be analysed and compared. This is defined as freedom from occlusion of the venous bypass.

    2 years

Secondary Outcomes (3)

  • Incidence of procedure-related mortality

    2 years

  • Incidence of 30-day mortality

    30 days

  • Incidence of limb salvage after procedure

    2 years

Study Arms (2)

Conventional Autologous Bypass

ACTIVE COMPARATOR
Procedure: Conventional Autologous Bypass

FRAMED Infrainguinal Venous Bypass

ACTIVE COMPARATOR
Procedure: FRAMED Infrainguinal Venous Bypass

Interventions

The harvested vein graft will be covered with a mesh.

FRAMED Infrainguinal Venous Bypass

The harvested vein graft will be used without a mesh coating.
