Multiple collaterals within the popliteal fossa were visualized (Figure 1).
CTA demonstrating complete occlusion of the proximal right popliteal artery (blue arrow) with reconstitution of flow distally from robust collateral vessels (red arrow).

CT angiography (CTA) of the lower extremities showed complete occlusion of the proximal right popliteal artery with significant reconstitution of flow distally from robust collateral vessels (Figure 2).
A band of soft tissue density (white arrow) is seen anterior to the right popliteal artery just distal to the occlusion.

fig3
A band of soft tissue density was visualized anterior to the right popliteal artery just distal to the occlusion, suggestive of a fibrous band contributing to the occlusion (Figure 3).
3D volume reconstruction obtained from axial source CTA images demonstrating occlusion of the right popliteal artery (blue arrow) with multiple adjacent collaterals.

A 3D volume reconstruction obtained from axial source CTA images showed occlusion of the right popliteal artery with adjacent collaterals (Figure 4).
