  • Figure 1
    Axial CTA image
     

    Axial CTA image reveals the occluded left popliteal artery entrapped by a more hypertrophic medial head of the left gastrocnemius that is located more laterally.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Special Focus: Embolism / Thrombosis;

    Axial CTA image shows the entrapment and compression of the non-opacified left popliteal artery by the more laterally inserted medial head of the gastrocnemius muscle.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Special Focus: Embolism / Thrombosis;
     
     
  • Figure 2
    Digital subtraction angiography
     

    Digital subtraction angiography (DSA) shows the collateral vessels that supply the distal part of the popliteal artery.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Fluoroscopy; Procedure: Diagnostic procedure; Special Focus: Embolism / Thrombosis;

    Digital subtraction angiography (DSA) shows the collateral vessels that supply the distal part of the popliteal artery.

    3D Volume rendering reconstruction

    3D Volume rendering reconstruction, on posterior view, shows the abrupt interruption of the left femoral artery and the collateral vessels that supply the more distal part of the popliteal artery.
