Lower extremity arterial reconstructions based on duplex scanning without preoperative angiography

• Abstract The high accuracy of duplex scanning in the diagnosis of lower limb arterial insufficiency has prompted us to perform aortoiliac and infrainguinal reconstructions (n = 77) in a selected group of patients with atherosclerotic occlusive disease of the lower extremity as well as graft revisions. Duplex findings were in agreement with operative findings in all patients in regard to the selection of the proximal and distal sites of the bypass procedures. In conclusion, we recommend with caution that, in patients with satisfactory duplex examination, vascular surgical reconstructions for lower limb ischaemia can be safely performed without preoperative angiography.
