[Value of triad operation in multilevel occlusion].

A triad procedure, i.e., aorto iliac inflow repair + profundaplasty + lumbar sympathectomy, offers a simple and effective approach for revascularisation in patients with multilevel arterial occlusive disease. Approximately 85% of the affected limbs at stage III-IV may return to a stage I or II. Only 10% require an additional distal bypass. Indications, technical aspects and late results are presented.
