    3D Volume Rendering reconstruction, on posterior view, demonstrates legs’ vascularization with the obstruction of the right popliteal artery and the presence of collateral vessels

     
    Area of Interest: unknown; Imaging Technique: Popliteal artery entrapment syndrome: multislice CTA vs DSA;

    1mm thin slice 3D reconstruction allows to evaluate the fine vascular anatomy of the knee

    Thick MPR sagittal recontruction

    Sagittal thick MPR image, using a soft tissue reconstruction algorithm allows an excellent demonstration of a small fibrous band linking the medial head of the gastrocnemius muscle to the lateral condyle of the femur,...

    Post-procedure CTA

    Post-procedure CTA shows residual intimal thickening of the right popliteal artery even if the vessel patency is obtained.

Sagittal thick MPR image, using a soft tissue reconstruction algorithm allows an excellent demonstration of a small fibrous band linking the medial head of the gastrocnemius muscle to the lateral condyle of the femur, crossing behind the popliteal artery producing occlusive compression of the vessel during stress.
