(a) Duplex ultrasonography demonstrated the femoral bifurcation and a heterogeneous echogenic mass (red circle). (b) Doppler ultrasound analysis revealed severe stenosis of the SFA (peak systolic velocity: 429.7 cm/s). (c) Contrast-enhanced CT revealed stenosis and adjacent arterial calcification.

An initial survey with DUS revealed a heterogeneous echogenic mass in the proximal superficial femoral artery (SFA) that caused hemodynamically significant stenosis, which was indicated by high blood flow of more than 4 m/s (Figure 1(a) and (b)). SFA and was adjacent to arterial wall calcification (Figure 1(c)). Surgical re-intervention was required for the stenosis with clinical ischemic symptoms, high blood flow on DUS, and low ABI.
The incision in the femoral artery revealed the intra-arterial lumen with an artifact mass, granulation, and small blood clots.

An incision in the femoral artery revealed the intra-arterial lumen with an artifact mass, granulation, and small blood clots (Figure 2).
