A 69 year old patient who, 10 years previously, had undergone popliteal artery aneurysm exclusion with a distal superficial femoral (SFA) to below knee popliteal artery bypass using the great saphenous vein presented with a non-pulsatile mass in the lower thigh. Computed tomography angiography revealed a “contrast ring” or “O” shaped 6.5 cm pseudoaneurysm at the proximal anastomosis fed through a large collateral via the profunda, in the presence of SFA occlusion. Pressurization of this unique pseudoaneurysm was considered low and thus it was non-pulsatile, thereby obscuring clinical evaluation. The pseudoaneurysm was resected and a bypass from the proximal SFA to the previous venous conduit below the knee was performed.
