Duplex Sonography, Angiography and CT Findings in the Second Patient.

(A) Thrombosed popliteal arterial aneurysm with a diameter of 2.8 × 2.5 cm. (B) Computed tomography angiography confirmed the occlusion of the distal superficial femoral artery (blue arrow) with refilling at the level of the proximal crural arteries (red arrows). (C, D) Popliteal arterial aneurysm was confirmed (red arrows). (E, F) Occlusion of the distal superficial femoral artery with contrast refilling in the proximal anterior tibial artery. Two overlapping Viabahn endoprostheses were placed. Because of (G) remaining thrombus formations (red arrows), (H) thrombectomy was performed, resulting in (I to L) brisk flow. (M to O) Duplex sonography revealed exclusion of the popliteal arterial aneurysm with triphasic flow in the popliteal artery.
