Digital subtraction angiography of Buerger’s disease

(a) Contrast media injection at the left common femoral artery reveals normal morphology (appropriate size and tapering) of the arteries of the proximal lower extremity. (b) Injection at the level of the above-knee popliteal artery shows occlusion of the popliteal artery with flow into collateral vessels (arrow). (c) Occlusion of all primary below knee runoff arteries with development of multiple “cork screw” collateral arteries (arrows).
