Patient
male, 73 year(s)
 
 
  • Figure 1
    Aortic and iliac aneurysms

    Coronal MIP CT images obtained in the early arterial phase show aortic fusiform infrarenal aneurysm and iliac bilateral saccular aneurysms. It also shows left external iliac vein with premature enhancement.

     
    Area of Interest: Arteries / Aorta; Veins / Vena cava; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
     
     
  • Figure 2
    Early venous opacification

    Axial CT images demonstrate early venous opacification (red arrow) and asymmetrical subcutaneous oedema (red asterisk).

     
    Area of Interest: Adrenals; Arteries / Aorta; Veins / Vena cava; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Fistula;
     
     
  • Figure 3
    Arteriovenous fistula

    Axial CT images obtained in the early arterial phase display fistulous track between a right common iliac artery aneurism and left common iliac vein.

     
    Area of Interest: Arteries / Aorta; Cardiovascular system; Veins / Vena cava; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Fistula;
     
     
  • Figure 4
    Fistulous track - MPR

    Sagital MPR CT images also reveal the fistulous track (red arrow) between right common iliac artery aneurysm and left common iliac vein.

     
    Area of Interest: Arteries / Aorta; Veins / Vena cava; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Aneurysms; Fistula;
     
     
  • Figure 5
    EVAR

    Coronal CT images show exclusion of the aortic and iliac aneurisms and arteriovenous fistula occlusion with endovascular stent grafting.

     
    Area of Interest: Arteries / Aorta; Interventional vascular; Veins / Vena cava; Imaging Technique: CT-Angiography; Procedure: Stents; Special Focus: Aneurysms; Fistula;
