[Digital subtraction angiography and large-film angiography of the pelvic and leg arteries]

Abstract

The diagnostic information and image quality of 1153 DSA studies of pelvic and lower limb arteries and of 104 conventional large film angiograms have been analysed. Using intra-arterial contrast, all large film angiograms and all DSA studies of the iliac, femoral, popliteal and upper calf arteries were satisfactory. For demonstrating the distal calf vessels and vessels in the foot, intra-arterial DSA was superior to large film angiography. Using intravenous DSA, 98% of the iliac, femoral and popliteal arteries were adequately demonstrated, although image quality was reduced.
